Abstract
To understand the influence of β-glucans structure on the emulsifying properties of protein-polysaccharide conjugates, sodium caseinate (NaCas) was utilized to form glycosylation conjugates with varying degrees of glycosylation (10.68-17.50%) using three β-glucans from bacteria, yeast, and oats. This process induced alterations in the secondary structure of protein. The nanoemulsions prepared with the glycosylated conjugates exhibited superior stability compared to those formulated solely with NaCas, particularly under conditions of drastic pH fluctuations and extended storage periods. The nanoemulsion prepared with the NaCas-Salecan conjugate demonstrated exceptional stability at pH 4 and 6, or storage for 20 days. Additionally, it significantly attenuated the oxidation of unsaturated fatty acids and exhibited the lowest levels of aggregation, flocculation, and free fatty acid release rate during in vitro digestion. This study suggested the potential of the NaCas-Salecan conjugates in enhancing the stability of nanoemulsions and facilitating the colorectal-targeted delivery of sea buckthorn fruit oil.

Abstract
Celiac disease and other types of gluten intolerance significantly affect the life quality of patients making them restrict the diet removing all food produced from wheat, rye, oat, and barley flour, and some other products. These disorders arise from protease resistance of poorly soluble proteins prolamins, contained in gluten. Enhanced proteolytic digestion of gliadins might be considered as a prospective approach for the treatment of celiac disease and other types of gluten intolerance. Herein, we tested a range of sulfated polymers (kappa-carrageenan, dextran sulfate and different polysaccharides from brown seaweeds, and a synthetic polystyrene sulfonate) for the ability to activate gliadin digestion by human digestive proteases, pepsin and trypsin. Sulfated polysaccharide from Fucus evanescens enhanced proteolytic digestion of gliadins from wheat flour and reduced its cytotoxicity on intestinal epithelial Caco-2 cell culture. Regarding the non-toxic nature of fucoidans, the results provide a basis for polymer-based drugs or additives for the symptomatic treatment of gluten intolerance.

Abstract
Interaction of proteins with charged macromolecules is involved in many processes in cells. Firstly, there are many naturally occurred charged polymers such as DNA and RNA, polyphosphates, sulfated glycosaminoglycans, etc., as well as pronouncedly charged proteins such as histones or actin. Electrostatic interactions are also important for "generic" proteins, which are not generally considered as polyanions or polycations. Finally, protein behavior can be altered due to post-translational modifications such as phosphorylation, sulfation, and glycation, which change a local charge of the protein region. Herein we review molecular modeling for the investigation of such interactions, from model polyanions and polycations to unfolded proteins. We will show that electrostatic interactions are ubiquitous, and molecular dynamics simulations provide an outstanding opportunity to look inside binding and reveal the contribution of electrostatic interactions. Since a molecular dynamics simulation is only a model, we will comprehensively consider its relationship with the experimental data.
