Peptide yog dab tsi?

Peptides yog cov tebchaw uas ob lossis ntau dua ob lub amino acids txuas nrog peptide bonds.Lawv yog cov khoom nruab nrab ntawm cov amino acids thiab cov protein, thiab cov khoom noj khoom haus thiab cov khoom tseem ceeb ntawm cov hlwb thiab lub neej.

Los ntawm kev tshawb pom cov protein nyob rau hauv 1838, mus rau thawj qhov kev tshawb pom ntawm polypeptide nyob rau hauv tib neeg lub cev los ntawm ob physiologists Bayliss thiab Starling ntawm University of London School of Medicine nyob rau hauv 1902. Peptides tau pom ntau tshaj ib puas xyoo.

Dej hiav txwv ntses collagen peptide yog muab rho tawm los ntawm marine ntses nrog dawb paug.Nws ruaj khov yog zoo heev tshaj li qub collagen molecule.Nrog rau cov yam ntxwv ntawm kev tiv thaiv tshav kub ntau, acid thiab alkali tsis kam, thiab tsis kam mus rau denaturation, nws tuaj yeem ncaj qha absorbed los ntawm tib neeg lub cev yam tsis zom thiab ua los ntawm txoj hnyuv.Dab tsi's ntau, nws muaj qhov zoo ntawm kev txo cov metabolic lub nra ntawm lub raum thiab muab tib neeg lub cev nrog zoo dua thiab yooj yim absorbed high-zoo proteins.

Marine ntses uas tsis tshua muaj peptide tuaj yeem ua rau calcium sib txuas nrog cov pob txha pob txha, tsis muaj kev poob lossis degeneration.

Dej hiav txwv ntses peptide tuaj yeem txhawb nqa kev nqus ntawm calcium, lub network qauv ntawm collagen yog qhov tseem ceeb heev rau kev tswj xyuas kev ncaj ncees ntawm cov pob txha thiab cov pob txha biomechanical zog.Cov polypeptides hauv collagen tuaj yeem cuam tshuam kev tsim cov stains los ntawm inhabiting cov haujlwm ntawm tyrosinase.
