The molecule is an arginine derivative that is L-arginine substituted by a phosphono group at N(omega)-position. It has a role as an animal metabolite. It is a phosphagen, a L-arginine derivative, a non-proteinogenic L-alpha-amino acid and a phosphoamino acid. It is a conjugate acid of a N(omega)-phosphonato-L-arginine.
