Collagen protein in its endogenous state is composed of three polypeptide amino acid chains (approximately 1000 amino acids per chain), connected in a fibrous triple helix structure by simple hydrogen bonds. This is great within the organism, its attributes lend to its amazing structural activity and capacity, it is the most abundant protein in your body for these very reasons. Yet to be able to boost your internal supply of collagen by taking a collagen supplement you must first extract the collagen protein from animal sources. Extraction via hydrolysis, creating "hydrolyzed collagen." To extract collagen protein you break down the hydrogen bonds of the triple helix structure and further you break down the long polypeptide chains into short peptide chains. Hydrolyzed collagen is the most broken down, shortest peptide chains derived from collagen protein that can be found in dietary supplements. Hydrolyzed collagen is synonymous with collagen peptides, and collagen hydrolysate.
Digestion of proteins, polypeptide chains, and peptide chains must break every covalent bond holding the amino acids together. Exposing the individual amino acids that can then be absorbed into the bloodstream. Consequently, ingesting shorter peptides containing fewer amino acids per chain makes the digestive process faster and more efficient. This is the reason for hydrolyzed collagen; fast and efficient bioavailability fit into capsules and tablets. To hydrolyzed collagen you also put the proteins through a series of purification steps to ensure integrity and quality of the partially broken down collagen.
