Bioactive Peptide
Bioactive Peptide — A peptide fragment that exerts a measurable biological effect beyond basic nutritional value, often released during enzymatic digestion of proteins.
What Is a Bioactive Peptide?
A bioactive peptide is a peptide sequence that produces a measurable biological effect in a living system. The term distinguishes functionally active peptides from inert sequence fragments. Bioactivity can range from receptor binding and signaling to antimicrobial activity, enzyme inhibition, or antioxidant effects.
Sources of Bioactive Peptides
