Enwere ike kewaa collagen n'ime: nnukwu molecule collagen na obere molecule collagen peptides.
Achịcha dị n'ime nri anyị na-erikarị nwere nnukwu protein ụmụ irighiri ihe dị arọ 300,000 dalton ma ọ bụ karịa, bụ nke a na-adịghị etinye ya ozugbo a richara ya, mana a na-agbajikwa ya n'ime amino acid n'ime usoro nri nri, na-eche ka a hazie ya. Amabeghị ma ha mechaa mebere collagen, nke nwere ọnụ ọgụgụ nnabata dị ala.
Ndị mmadụ ejikwala collagen nwere ibu ihe ruru 6000 dalton site na usoro acid-base na enzymatic cleavage usoro wee kpọọ ya collagen peptide. A peptide bụ ihe dị n'etiti amino acids na protein macromolecular. Amino acid abụọ ma ọ bụ karịa na-agbaze ma kpokọta ya ka ha mepụta ọtụtụ peptide bond iji mepụta peptide, na ọtụtụ peptides na-apịaji n'ọtụtụ ọkwa iji mepụta protein molecule. Peptides bụ iberibe protein ndị dị na ya nwere ụmụ irighiri ihe dị nha nanometer, bụ́ ndị afọ, eriri afọ, arịa ọbara na akpụkpọ ahụ na-amịkọrọ ngwa ngwa, ọnụ ọgụgụ mmịnye ha dịkwa elu karịa nke nnukwu protein molecule.
A na-ekewa peptides collagen nwere ihe dị arọ 6000 dalton ma ọ bụ ihe na-erughị ya n'ime peptides nwere ịdị arọ molekul nke 1000-6000 dalton na peptides nwere ịdị arọ molecular nke 1000 dalton ma ọ bụ ihe na-erughị ya. N'ozuzu, ọnụọgụ amino acid dị na oligopeptide sitere na abụọ ruo itoolu. Dị ka ọnụ ọgụgụ nke amino acid dị na peptide dị iche iche, e nwere aha dị iche iche: ihe mejupụtara site na akpịrị ịkpọ nkụ nke mkpụrụ ndụ amino acid abụọ ka a na-akpọ dipeptide, na otu ihe atụ, e nwere tripeptide, tetrapeptide, pentapeptide, wdg, ruo itoolu. peptides; A na-akpọkarị ogige nke etolite site na njupụta nke 10-50 amino acid molecules polypeptide.
Na 1960, egosila na oligopeptide nwere ike itinye uche na-enweghị eriri afọ, nke nwere ike ibelata ibu nke eriri afọ na imeju ma melite bioavailability; na ọ nwere ike isonye ozugbo na njikọ nke collagen mmadụ na-emebighị n'ime amino acid, ebe peptide enweghị ike imezu ihe ndị a.
