1-Aminocyclopropane-1-carboxylic acid (ACC) is a disubstituted cyclic α-amino acid in which a cyclopropane ring is fused to the C_α atom of the amino acid. It is a white solid. Many cyclopropane-substituted amino acids are known, but this one occurs naturally.^[2]^{[verification needed]} Like glycine, but unlike most α-amino acids, ACC is not chiral.
