Lysine (sau luv li Lys lossis K), sau los ntawm codons AAA thiab AAG, yog α-amino acid uas tau siv hauv biosynthesis ntawm cov protein. Nws muaj α-amino pab pawg (uas yog nyob rau hauv protonated −NH3+ daim ntawv nyob rau hauv kev mob lom neeg), α-carboxylic acid pawg (uas yog nyob rau hauv deprotonated −COO− daim ntawv nyob rau hauv kev mob nkeeg), thiab ib sab saw lysyl (( CH2) 4NH2), cais nws raws li tus nqi (ntawm lub cev pH), aliphatic amino acid. Nws yog qhov tseem ceeb hauv tib neeg, txhais tau tias lub cev tsis tuaj yeem ua ke nws thiab yog li nws yuav tsum tau txais los ntawm kev noj zaub mov.

Lysine yog lub hauv paus, ib yam li arginine thiab histidine. Cov pab pawg ε-amino feem ntau koom nrog kev sib txuas hydrogen thiab ua lub hauv paus dav hauv catalysis. Cov pab pawg amino-amino (NH3+) txuas nrog cov pa roj carbon thib tsib los ntawm α-carbon, uas txuas nrog rau pawg carboxyl (C = OOH).

Kev hloov pauv tom qab ntau yam suav nrog methylation ntawm ε-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 seem hauv endoplasmic reticulum lossis Golgi cov cuab yeej siv los cim qee cov protein rau tso tawm los ntawm lub cell. Hauv opsins zoo li rhodopsin thiab pom kev opsins (cim los ntawm cov noob OPN1SW, OPN1MW, thiab OPN1LW), retinaldehyde tsim Schiff puag nrog kev khaws cia lysine seem, thiab kev sib cuam tshuam ntawm lub teeb nrog pab pawg retinylidene ua rau teeb liab hloov pauv hauv qhov muag pom kev (Pom lub voj voog pom kom paub meej). Qhov tsis txaus yuav ua rau dig muag, nrog rau ntau lwm yam teeb meem vim nws muaj nyob hauv cov protein ntau.

Cov khoom lag luam nyob rau hauv patent tau muab rau R& D lub hom phiaj nkaus xwb. Txawm li cas los xij, lub luag haujlwm zaum kawg tshwj xeeb tshaj yog nrog tus neeg yuav khoom.
