Abstract
Glutamine, the most abundant amino acid in the body, plays a critical role in preserving immune function, nitrogen balance, intestinal integrity, and resistance to infection. However, its limited solubility and instability present challenges for its use a functional nutrient. Consequently, there is a preference for utilizing glutamine-derived peptides as an alternative to achieve enhanced functionality. This article aims to review the applications of glutamine monomers in clinical, sports, and enteral nutrition. It compares the functional effectiveness of monomers and glutamine-derived peptides and provides a comprehensive assessment of glutamine-derived peptides in terms of their classification, preparation, mechanism of absorption, and biological activity. Furthermore, this study explores the potential integration of artificial intelligence (AI)-based peptidomics and synthetic biology in the de novo design and large-scale production of these peptides. The findings reveal that glutamine-derived peptides possess significant structure-related bioactivities, with the smaller molecular weight fraction serving as the primary active ingredient. These peptides possess the ability to promote intestinal homeostasis, exert hypotensive and hypoglycemic effects, and display antioxidant properties. However, our understanding of the structure-function relationships of glutamine-derived peptides remains largely exploratory at current stage. The combination of AI based peptidomics and synthetic biology presents an opportunity to explore the untapped resources of glutamine-derived peptides as functional food ingredients. Additionally, the utilization and bioavailability of these peptides can be enhanced through the use of delivery systems in vivo. This review serves as a valuable reference for future investigations of and developments in the discovery, functional validation, and biomanufacturing of glutamine-derived peptides in food science.

Effect of acute ammonia toxicity on inflammation, oxidative stress and apoptosis in head kidney macrophage of Pelteobagrus fulvidraco and the alleviation of curcumin. Comp Biochem Physiol C Toxicol Pharmacol 2021; 248:109098. [PMID: 34139380 DOI: 10.1016/j.cbpc.2021.109098] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 05/23/2021] [Accepted: 05/31/2021] [Indexed: 12/18/2022]
Abstract
Ammonia is one of the most major pollutant and stress factors of aquaculture systems, and has seriously endangered fish health. However, few studies have been performed on mechanisms of the detrimental impact of ammonia stress and mitigation in fish. A study was carried out to investigate the response of genes involved in inflammation, antioxidation, polarization and apoptosis in head kidney macrophages to acute ammonia toxicity, and the alleviation effect of curcumin. The cells were divided into six groups, as follows: The control group composed of untreated macrophages (CON), the experimental groups, consisting of macrophages treated with 0.23 mg L-1 ammonia (AM), 45 μmol L-1 curcumin (CUR), 0.23 mg L-1 ammonia and 5 μmol L-1 curcumin (5A), 0.23 mg L-1 ammonia and 25 μmol L-1 curcumin (25A), 0.23 mg L-1 ammonia and 45 μmol L-1 curcumin (45A). The cells were pretreated with different concentrations of curcumin for 1 h and then incubated with ammonia for 24 h. The results showed that ammonia poisoning could increase ROS levels, up-regulate the expression of antioxidant enzymes (SOD and GPx), inflammatory cytokines (IL-1, IL-6 and TNF-α) and inflammatory mediators (NF-κB p65 and COX-2), decrease cell viability, down-regulate the expression of M2 marker (Arg-1) and anti-apoptosis (Bcl-2), but curcumin could alleviate the adverse effect of ammonia toxicity. Overall, these results have important implications for understanding of the mechanism of ammonia toxicity and the mitigating effect of curcumin in fish.

Abstract
To understand the toxic mechanism of ammonia and identify effective biomarkers on the oxidative stress for the fish Carassius auratus red var., acute and chronic toxicity tests were conducted. The 96-h LC50 of total ammonia nitrogen (TAN) for C. auratus was 135.4 mg L-1, the corresponding unionized ammonia (NH3) concentration was 1.5 mg L-1. The activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), glutathione-peroxidase (GSH-Px) and glutathione (GSH) showed an increase with a subsequent falling, while the malondialdehyde (MDA) increased during the chronic test. The SOD, MDA, and GSH could be effective biomarkers to evaluate the TAN oxidative stress, the maximum acceptable toxicant concentration (MATC) was 11.3 mg L-1 for TAN. To our knowledge, this is the first study to propose biomarkers to evaluate potential environmental risk and establish a risk threshold for TAN in C. auratus.
