Peptide yog dab tsi?

Peptide yog hais txog ib hom kev sib txuas uas cov qauv molecular ntawm cov amino acids thiab cov protein, nws yog tsim ntawm cov kab ke ntuj sib txawv thiab cov qauv txheej txheem polyplectides. Txhua tus peptide muaj lawv tus qauv tshwj xeeb, thiab cov qauv ntawm kev sib txawv peptides nyob ntawm lawv tus kheej ua haujlwm. Peptide muaj cov ntsiab lus tseem ceeb hauv kev siv hluav taws xob, tab sis nws muaj kev ua haujlwm ntawm lub cev. Ntawm lawv, peptides uas tuaj yeem tswj hwm lub cev muaj sia muaj sia muaj sia uas tau hu ua haujlwm peptide peptide lossis biologically dhia peptide. Thaum ntxov 20^thXyoo pua, kev ua tiav ntawm cov synthesize dipepride kos npe rau peptide science.

Ntau qhov tseeb ua pov thawj tias cov protein tsis tuaj yeem nqus tau nyob rau hauv daim ntawv ntawm cov amino acids, tab sis kuj nqus tau ntau yam peptides. Nws yog feem ntau ntseeg hais tias cov dipeptides thiab tripeptides mus rau hauv plab hnyuv thiab ces hydrolyzed by peptidase cell thiab ces hydrolyzed los ntawm cov ntshav ncig hauv daim ntawv ntawm cov amino acids dawb. Peptide cov cab kuj nkag mus rau hauv kev ncig.

Cov kev tshawb fawb txuas ntxiv pom tias cov protein ntau los ntawm tib neeg lub cev yog zom thiab nqus tau ntawm cov hnyuv tom qab nqus tau dawb amino acids yog me me.

Protein tau nqus tau nyob rau hauv daim ntawv ntawm peptide, uas tsis tsuas yog zam kev sib tw ntawm cov amino acids, tab sis kuj tseem yuav txo cov nyhuv rov qab ntawm cov osmotic siab rau tib neeg lub cev. Yog li no, muab cov khoom noj khoom haus rau tib neeg lub cev hauv daim ntawv ntawm Peptide yog qhov zoo rau kev ua haujlwm nrawm ntawm peptide. Dab tsi ntxiv, kev muaj txiaj ntsig zoo ntawm peptide yog siab dua li cov amino acids. Yog li ntawd, collagen peptide tau dhau los ua qhov chaw kub tshiab hauv thaj chaw protein kev noj haus, thiab cov zaub mov molecular peptide me me lossis oligopthide cov zaub mov muaj kev tshawb fawb.
