Arginin nyaéta asam amino anu rumusna (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H. Molekulna boga gugus guanidino anu napel dina wangun baku asam amino. Dina pH pisiologis, asam karboksilat ngalaman deprotonasi (−CO2−), anapon gugus amino jeung guanidino diprotonasi, ngahasilkeun hiji kation. Ngan énantiomér l-arginin (lambang Arg atawa R) anu kapanggih alami.[1] Résidu Arg mangrupakeun komponén galib dina protéin, disandi ku kodon CGU, CGC, CGA, CGG, AGA, jeung AGG.[2] Gugus guanidin dina arginin téh prékursor pikeun biosintésis oksida nitrat.[3] Sakumaha galibna asam amino, padetanana bodas jeung leyur dina cai.
