Lysine (sau ua Lys lossis K), nkag los ntawm codons AAA thiab AAG, yog an-amino acid uas siv nyob rau hauv biosynthesis ntawm cov protein. Nws muaj group-amino pawg (uas yog nyob rau hauv daim ntawv tiv thaiv −NH3+ daim ntawv nyob rau hauv kev mob) CH2) 4NH2), cais nws raws li kev them nyiaj (ntawm physiological pH), aliphatic amino acid. Nws yog qhov tseem ceeb hauv tib neeg, txhais tau hais tias lub cev tsis tuaj yeem coj nws thiab yog li nws yuav tsum tau txais los ntawm kev noj haus.

Lysine yog lub hauv paus, zoo li muaj arginine thiab histidine. Group-amino pab pawg feem ntau koom nrog qhov kev sib koom ua ke hydrogen thiab raws li ib qho qauv dav hauv catalysis. Cov pab pawg ε-amino (NH3 is) yog txuas nrog lub pa roj carbon tsib los ntawm the-carbon, uas txuas nrog cov pawg carboxyl (C = OOH).

Cov kev hloov kho tom qab muaj xws li methylation ntawm group-amino pawg, muab methyl-, dimethyl-, thiab trimethyllysine (tom kawg tshwm sim hauv calmodulin); kuj acetylation, sumoylation, ubiquitination, thiab hydroxylation - ua cov hydroxylysine hauv collagen thiab lwm cov protein. O-Glycosylation ntawm hydroxylysine residues hauv endoplasmic reticulum lossis Golgi apparatus siv los khij qee cov protein tawm ua kom lub ntsej muag tawm ntawm tes. Nyob rau hauv opsins li rhodopsin thiab opsins pom tau zoo (encoded los ntawm caj ces OPN1SW, OPN1MW, thiab OPN1LW), retinaldehyde cov txheej txheem Schiff puag nrog cov lysine tshwj tseg, thiab kev sib cuam tshuam ntawm lub teeb nrog cov pab pawg retinylidene ua rau lub teeb liab sib hloov hauv kev pom xim (pom kev siv lub voj voog) kom paub meej). Qhov tsis txaus yuav ua rau dig muag, ntxiv rau ntau lwm yam teeb meem vim nws qhov ubiquitous nyob hauv cov protein.
