6. Inactive hydrophobic: suav nrog glycine, alanine, valine, leucine thiab isoleucine. Cov amino acids no feem ntau yuav faus rau hauv cov protein sab hauv. Lawv R pab pawg tsis tsim cov ntawv cog lus hydrogenthiab tsis tshua koom nrog cov tshuaj tiv thaiv.
Cov amino acids twg tuaj yeem tsim cov ntawv cog lus hydrogen?
Cov amino acids asparagine thiab glutaminemuaj cov pab pawg amide hauv lawv cov chains uas feem ntau yog hydrogen-bonded thaum twg lawv tshwm sim nyob rau hauv cov protein.
Qhov seem twg tuaj yeem tsim cov ntawv cog lus hydrogen?
Muaj ntau cov amino acid residues uas tuaj yeem tsim H-bonds ntawm lawv cov saw txuas ntxiv rau lawv pawg peptide. Tej zaum qhov tseem ceeb tshaj plaws ntawm pawg no yog cov saw hlau sab uas muaj hydroxyl (Ser thiab Thr) lossis amide (Asn thiab Gln) pawg lossis cov khoom seem xws li Lys, Arg, Asp, thiab Glu.
Puas amino tsim cov ntawv cog lus hydrogen?
Hydrophilic amino acids muaj oxygen thiab nitrogen atoms, uas tuaj yeem tsim hydrogen bonds nrog water. Cov atoms no muaj qhov sib npaug ntawm cov khoom siv hluav taws xob, tsim cov polar molecule uas tuaj yeem cuam tshuam thiab tsim hydrogen bonds nrog dej.
Yuav ua li cas cov amino acid feem ntau yuav koom nrog hydrogen bonds?
Puas yog cov amino acid no feem ntau yuav koom nrog hydrogen bonds, ionic bonds, hydrophobic interactions thiab/los yog disulfide bonds? Vim li cas? Serine yog qhia. Hydrogen bonding.
