Egg Peptides From American Shad Extend Lifespan and Healthspan in Caenorhabditis elegans via Lipid Metabolism Remodeling and Antioxidant Defense

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
A novel shad egg peptide (EP) significantly extends Caenorhabditis elegans lifespan through a dual antiaging mechanism. EP systematically remodels lipid metabolism to reinforce cell membranes by promoting beneficial fatty acid biosynthesis and suppressing degradation. Simultaneously, its potent antioxidant activity alleviates oxidative damage, shifting

Comprehensive Peptide Profiling Reveals the Influence of Streptococcus Thermophilus, Lactobacillus Delbrueckii Subsp. bulgaricus, and Endogenous Milk Proteases on the Hydrolysis of Milk Proteins During Early‐Stage Lactic Acid Fermentation

ChemFoodChem, Volume 2, Issue 3, September 2026.
Untargeted peptide profiling investigates how S. thermophilus, Lb. bulgaricus, and endogenous milk enzymes impact proteolysis during early‐stage milk fermentation. ≥ 3000 identified peptides show the strongest influence of LB on the peptide profile and number of bioactive peptides. Shorter peptides are mostly formed by LB and hydrolyzed by ST.
