Alanine (sau luv li Ala lossis A; nkag los ntawm codons GCU, GCC, GCA, thiab GCG) 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 lom neeg), thiab ib sab saw methyl pawg, cais nws ua nonpolar (ntawm physiological pH), aliphatic amino acid. Nws tsis yog qhov tseem ceeb hauv tib neeg, txhais tau tias lub cev tuaj yeem ua ke nws.

L-isomer (sab laug tes) ntawm alanine yog ib qho ntawm 20 cov amino acids uas tau teev tseg los ntawm tib neeg cov caj ces. L-Alanine yog qhov thib ob tsuas yog leucine hauv qhov tshwm sim, suav txog 7.8% ntawm thawj cov qauv hauv cov qauv ntawm 1,150 cov protein. Daim ntawv sab xis, D-Alanine tshwm sim hauv cov kab mob cell phab ntsa thiab hauv qee yam tshuaj tua kab mob peptide.
