Salmon protamine peptides

Salmon protamine peptides are primarily found in salmon testes (milt) and are basic proteins/peptides rich in arginine. In fish sperm, DNA binds with protamine to form a nucleoprotein structure. Research indicates that protamines from fish milt are particularly rich in arginine and lysine.

When salmon protamine undergoes enzymatic hydrolysis (e.g., using trypsin):

Salmon milt → Protamine extraction → Enzymatic hydrolysis → Salmon protamine peptides

The resulting product is a protamine hydrolysate composed of multiple small peptides, rather than a single compound.

      Current research focuses on several key areas:① Antioxidant activity—currently the most well-established area of ​​research
② Anti-inflammatory potential③ ACE inhibition—potential value for cardiovascular health
