Amino acids yog cov qauv tsim los ntawm cov proteins uas tau tsim. Thaum cov amino acids daim ntawv cog lus rau ib leeg, nws ua tiav hauv daim ntawv ntawm amide, ua kev sib txuas uas hu ua peptide linkage. Qhov no tuaj yeem ua piv txwv nrog ob qhov yooj yim amino acids, glycine thiab alanine.
YPuas alanine yog peptide?
Alanine (lub cim Ala lossis A) yog α-amino aciduas yog siv rau hauv biosynthesis ntawm cov protein. … Daim ntawv sab xis, D-alanine, tshwm sim hauv polypeptides hauv qee cov kab mob hauv cov phab ntsa ntawm tes thiab hauv qee cov tshuaj tua kab mob peptide, thiab tshwm sim hauv cov ntaub so ntswg ntawm ntau cov crustaceans thiab molluscs ua ib qho osmolyte.
Alanine muaj pes tsawg daim ntawv cog lus?
Nyob hauv alanine-H2O, cov dej molecule tsim ob intermolecular hydrogen bonds tsim ib lub voj voog rau-membered, thaum nyob rau hauv alanine- (H2O)2 cov dej molecules tsim peb hydrogen. daim ntawv cog lus ua ib lub nplhaib yim-tus tswv cuab.
Cov amino acids twg tuaj yeem tsim peptide bonds?
Ib daim ntawv cog lus peptide yog hom amide ntawm covalent chemical bonding ob sib law liag alpha-amino acidslos ntawm C1 (carbon tooj ib) ntawm ib alpha-amino acid thiab N2 (nitrogen tus naj npawb ob) ntawm lwm tus, nrog rau peptide lossis cov saw hlau protein.
Yuav ua li cas cov enzymes muaj peptide bonds?
4.2 Proteases . Peptidases lossis proteases yog cov enzymes uas ua rau lub cleavage ntawm peptide bonds hauv cov proteins. Nyob ntawm qhov xwm txheej ntawm pawg ua haujlwm ntawmCov chaw nquag, lawv muab faib ua serine proteases, aspartic proteases, metalloproteases, cysteine proteases, thiab endopeptidases.
