The creation of bioactive peptides (BPs) from dietary proteins holds considerable promise for the expansion of functional foods and nutraceuticals. BPs have a variety of important roles in the living body, including antioxidative, antimicrobial, immunomodulatory, hypocholesterolaemic, antidiabetic, and antihypertensive properties. To preserve the quality and microbiological safety of food items, BPs have been used as food additives. Additionally, peptides may be employed as functional components in the treatment or prevention of chronic and lifestyle-related disorders. This article's main goal is to draw attention to the functional, dietary, and health advantages of using BPs in food items. Therefore, it examines the mechanisms of action and medicinal uses of BPs. This review also focuses on various uses of bioactive protein hydrolysates for enhancing food items' quality and shelf life as well as for bioactive packaging. Researchers interested in physiology, microbiology, biochemistry, and nanotechnology, as well as members of the food business, are advised to read this article.

Diabetic cognitive dysfunction is one of the important comorbidities and complications of diabetes, which is mainly manifested by loss of learning ability and memory, behavioural disorders, and may even develop into dementia. While traditional anti-diabetic medications are effective in improving cognition and memory, long-term use of these medications can be accompanied by undesirable side effects. Therefore, there is an urgent need to find safe and effective alternative therapies.

The COVID-19 pandemic drove a uniquely fervent pursuit to explore the potential of peptide, antibody, protein, and small-molecule based antiviral agents against severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). The interaction between the SARS-CoV2 spike protein with the angiotensin-converting enzyme 2 (ACE2) receptor that mediates viral cell entry was a particularly interesting target given its well described protein-protein interaction (PPI). This PPI is mediated by an α-helical portion of ACE2 binding to the receptor binding domain (RBD) of the spike protein and thought to be susceptible to blockade through molecular mimicry.

Diabetic wounds are characterized by chronic inflammation, reduced angiogenesis, and insufficient collagen deposition, leading to impaired healing. Extracellular vesicles (EVs) derived from adipose-derived mesenchymal stem cells (ADSC) offer a promising cell-free therapeutic strategy, yet their efficacy and immunomodulation can be enhanced through bioactivation. In this study, we developed calcium silicate (CS)-stimulated ADSC-derived EVs (CSEV) incorporated into collagen hydrogels to create a sustained-release system for promoting diabetic wound healing.

The bioactive peptides in Jinhua ham could be released into the broth during cooking. After comparing peptide antibacterial activity from Jinhua ham broth with varying cooking durations, the cooking-2-h broths were selected for further analysis using cation-exchange and reverse-phase-liquid chromatography. The purified peptide sequences were subsequently synthesized and tested for their antibacterial activity.

This study identified the amino acid sequences of peptides generated from the enzymatic hydrolysis of goat milk proteins from two different sources and annotated their functional activities. Peptidomics and molecular docking approaches were used to investigate the antioxidant and ACE inhibitory properties of the unique peptides, revealing the molecular mechanisms underlying their bioactivity. In vitro experiments showed that the IC50 values for ACE inhibition of the four peptides (LSMTDTR, QEALELIR, NIPVGILR, and QAQNVQHY) were 2.
