Hydrolyzed collagen peptides — molecular-weight distribution, source identity, and the analytical characterization research labs document.
Hydrolyzed collagen peptides are a heterogeneous mixture of low-molecular-weight peptides produced by enzymatic or acid hydrolysis of collagen. Research-grade reference lots are characterized by source species, average molecular weight, and amino-acid composition.
Key characterization parameters
- Average molecular weight (typically 2–5 kDa for low-MW research lots)
- Source species (bovine, marine, porcine)
- Amino-acid composition with hydroxyproline content
- Solubility profile in aqueous buffers
