Biochim Biophys Acta Gen Subj 2023; 1867:130254. [PMID: 36243203 DOI: 10.1016/j.bbagen.2022.130254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 09/08/2022] [Accepted: 10/10/2022] [Indexed: 11/13/2022]
Abstract
BACKGROUND In this study we investigated hydrogen bonding interactions in hydrated and frozen solutions of different cryoprotective agents (CPAs) including dimethyl sulfoxide, glycerol, ethylene glycol, propylene glycol, and trehalose. We also investigated the effect of CPAs on ice crystal growth during storage and correlated this with storage stability of liposomes. METHODS FTIR spectroscopy was used to study hydrogen bonding interactions in CPA solutions in H2O and D2O, and their thermal response was analyzed using van 't Hoff analysis. The effect of CPAs on ice crystal growth during storage was investigated by microscopy and correlated with storage stability of liposomes encapsulated with a fluorescent dye. RESULTS Principal component analyses demonstrated that different CPAs can be recognized based on the shape of the OD band region only. Chemically similar molecules such as glycerol and ethylene glycol closely group together in a principal component score plot, whereas trehalose and DMSO appear as condensed separated clusters. The OH/OD band of CPA solutions exhibits an overall shift to higher wavenumbers with increasing temperature and changed fractions of weak and strong hydrogen interactions. CPAs diminish ice crystal formation in frozen samples during storage and minimize liposome leakage during freezing but cannot prevent leakage during frozen storage. CONCLUSIONS CPAs can be distinguished from one another based on the hydrogen bonding network that is formed in solution. DMSO-water mixtures behave anomalous compared to other CPAs that have OH groups. CPAs modulate ice crystal formation during frozen storage but cannot prevent liposome leakage during frozen storage.

Abstract
Glycine, the most fundamental amino acid, albeit studied for many decades, has kept researchers captivated with interesting structural variations relevant to important biological, astrophysical and technological applications. We report here a noticeable effect of deuteration on the three dimensional hydrogen bonding network of α-glycine using low temperature infrared absorption studies in a wide spectral range, corroborated with Raman scattering studies. These systematic studies in the range 300-4.2 K have demonstrated a relatively compact assembly of glycine molecules in the three dimensional bilayered structure of hydrogenated glycine (gly-h) at low temperatures. This is inferred from a remarkable temperature effect in the weak intra-bilayer hydrogen bond ~ along the b-axis, which strengthens upon cooling. A pronounced increase in the intensity of NH3 torsional and NH stretching modes has been observed. This is accompanied with a large rate of stiffening and softening respectively of these modes upon cooling and a change in slope across 210 K and 80 K. In contrast, the D---O hydrogen bond lengths in fully deuterated isotope (gly-d), as estimated using empirical correlation, show that the weak intra-bilayer hydrogen bond is not strengthened upon cooling down to 180 K, whereas the stronger intra-layer hydrogen bonds in the ac-plane become further strong. The ND3 torsional vibrations show no temperature effect. This implies a relatively stable two dimensional layered structure formed by strongly hydrogen bonded glycine sheets in the ac-plane. Below 180 K, similar qualitative trends have been obtained for the hydrogen bond lengths in the two isotopes. In addition, temperature induced variation of the characteristic "indicator" band of zwitterionic gly-h and gly-d has also been reported.

The intrinsically disordered protein LEA7 from Arabidopsis thaliana protects the isolated enzyme lactate dehydrogenase and enzymes in a soluble leaf proteome during freezing and drying. BIOCHIMICA ET BIOPHYSICA ACTA-PROTEINS AND PROTEOMICS 2015; 1854:1517-25.

Abstract
The accumulation of Late Embryogenesis Abundant (LEA) proteins in plants is associated with tolerance against stresses such as freezing and desiccation. Two main functions have been attributed to LEA proteins: membrane stabilization and enzyme protection. We have hypothesized previously that LEA7 from Arabidopsis thaliana may stabilize membranes because it interacts with liposomes in the dry state. Here we show that LEA7, contrary to this expectation, did not stabilize liposomes during drying and rehydration. Instead, it partially preserved the activity of the enzyme lactate dehydrogenase (LDH) during drying and freezing. Fourier-transform infrared (FTIR) spectroscopy showed no evidence of aggregation of LDH in the dry or rehydrated state under conditions that lead to complete loss of activity. To approximate the complex influence of intracellular conditions on the protective effects of a LEA protein in a convenient in-vitro assay, we measured the activity of two Arabidopsis enzymes (glucose-6-P dehydrogenase and ADP-glucose pyrophosphorylase) in total soluble leaf protein extract (Arabidopsis soluble proteome, ASP) after drying and rehydration or freezing and thawing. LEA7 partially preserved the activity of both enzymes under these conditions, suggesting its role as an enzyme protectant in vivo. Further FTIR analyses indicated the partial reversibility of protein aggregation in the dry ASP during rehydration. Similarly, aggregation in the dry ASP was strongly reduced by LEA7. In addition, mixtures of LEA7 with sucrose or verbascose reduced aggregation more than the single additives, presumably through the effects of the protein on the H-bonding network of the sugar glasses.

Abstract
Previous THz spectroscopy of the TNT explosive precursor, 2,4-dinitrotoluene (DNT), has been restricted to room temperature (apart from one set of data at 11 K). Here, for the first time, we investigate the spectrum as the temperature is systematically varied, from 7 to 245 K. Many new features appear in the spectrum on cooling below room temperature. As well as the five absorption lines observed previously, we observe five additional lines. In addition, a new room-temperature line at 8.52 THz (281 cm(-1)) is observed. Six of the lines red-shift with temperature and four of them blue-shift. The blue shift is explained by interplay between intramolecular and intermolecular hydrogen bonds. The variation in line width and line intensity with temperature is not systematic, although a conspicuous decrease in line intensity with temperature is observed in all cases. Modeling with hybrid PBE0 and TPSSh functionals helps identify absorption modes.

Abstract
The effect of the addition of non-reducing sugars or methylcellulose on the matrix physical properties and rate of non-enzymatic browning (NBR) between exogenous glucose+lysine in a starch-based glassy matrix were studied, using the methods of luminescence and FTIR. Amorphous starch-based matrices were formulated by rapidly dehydrating potato starch gel mixed with additives at weight ratios of 7:93 (additive:starch). Data on the phosphorescence emission energy and lifetime from erythrosin B dispersed in the matrices indicated that sugars decreased starch matrix mobility in a Tg-dependent manner, except for trehalose that interacted with starch in a unique mode, while methylcellulose, the additive with the highest Tg, increased the molecular mobility. Using FTIR, we found that methylcellulose decreased the strength of hydrogen bond network and sugars enhanced the hydrogen bond strength in the order: trehalose>maltitol>sucrose. Comparing those changes with the rate of NBR between exogenous glucose+lysine, we suggest that NBR rates are primarily influenced by matrix mobility, which is modulated by the hydrogen bond network, and interactions among components.

Abstract
Fourier-transform infrared spectroscopy (FTIR) was used to study the hydrogen-bonding interactions that take place in vitrified carbohydrates of different chain lengths. The band position of the OH stretching band (vOH) and the shift in band position as a function of temperature were determined from the FTIR spectra as indicators for the length and strength of intermolecular hydrogen bonds, respectively. Differential scanning calorimetry (DSC) was used to corroborate the FTIR studies and to measure the change in heat capacity (delta C(p)) that is associated with the glass transition. We found that with increasing T(g), the band position of vOH increases, the wavenumber-temperature coefficient of vOH in the glassy state, WTC(g), increases, whereas (delta C(p) decreases. The positive correlation that was found between vOH and the glass transition temperature, T(g), indicates that the length of the hydrogen bonds increases with increasing T(g). The increase in WTC(g) with increasing T(g) indicates that the average strength of hydrogen bonding decreases with increasing T(g). This implies that oligo- and polysaccharides (high T(g)) have a greater degree of freedom to rearrange hydrogen bonds during temperature changes than monosaccharides (low T(g)). Interestingly, WTC(g) and delta C(p) showed a negative linear correlation, indicating that the change in heat capacity during the glass transition is associated with the strength of the hydrogen-bonding network in the glassy state. Furthermore, we report that introduction of poly-L-lysine in glassy sugar matrices decreases the average length of hydrogen bonds, irrespective of the size of the carbohydrate. Palmitoyl-oleoyl-phosphatidylcholine (POPC) vesicles were found to only interact with small sugars and not with dextran.

Abstract
Few tissues or organisms can survive the removal of nearly all their intra and extracellular water. These few have developed specialized adaptations to protect their cellular components from the damage caused by desiccation and rehydration. One mechanism, common to almost all such organisms, is the accumulation of disaccharides within cells and tissues at the onset of dehydration. This adaptation has been extensively studied and will not be considered in this review. It has become increasingly clear that true desiccation tolerance is likely to involve several mechanisms working in concert; thus, we will highlight several other important and complimentary adaptations found especially in the dehydration-resistant tissues of higher plants. These include the scavenging of reactive oxygen species, the down-regulation of metabolism, and the accumulation of certain amphiphilic solutes, proteins, and polysaccharides.

Abstract
The title compound, PrCl3.C6H12O6.9 H2O crystallized in the monoclinic space group P2(1)/n with cell dimensions a = 15.8293(3), b = 8.67750(10), c = 16.2292(3) A, beta = 107.0788(8) degrees, V = 2130.92(6) A3 and Z = 4. Each Pr ion is coordinated to nine oxygen atoms, two from the inositol and seven from water molecules, with Pr-O distances from 2.4729 to 2.6899 A; the other two water molecules are hydrogen-bonded. No direct contacts exist between Pr and Cl. There is an extensive network of hydrogen bonds formed by hydroxyl groups, water molecules, and chloride ions. The IR spectra of Pr-, Nd-, and Sm-inositol complexes are similar, which shows that the three metal ions have the same coordination mode. The IR results are consistent with the crystal structure.

Abstract
Infrared spectra in the range 400-4000 cm(-1) of three pentitols--ribitol, xylitol, D-arabinitol, and of three pyranosides--methyl alpha-D-manno-, methyl alpha-D-gluco- and methyl beta-D-galactopyranoside, as polycrystalline solids of both the pure OH and > 90% isotopically substituted OD compounds, were recorded at 20-300 K. In the low temperature spectra of the OH substances, at least three isolated narrow bands in the stretching mode and about ten narrow bands in the out-of-plane-bending mode range (< 1000 cm(-1)) are affected by cooling. Almost all have counterparts in the respective OD spectra with frequency ratios of 1.30-1.40. On this basis, they are assigned to OH groups bonded in H-bonds of different strengths (from 10 to 50 kJ mol(-1)). The average number of the OH...O hydrogen bonds is found to be two to three times larger than indicated by the stretching mode only or by structural data. The newly measured peak frequencies of the very narrow decoupled stretching mode bands show a correlation between the red shift (delta nu) and the H-bond length. As previously found for tetritols, the presence of weak H-bonds (bond energy < 14 kJ mol(-1)) is related to the different water sorption capabilities of the pentitols.
