Products Description of 1-Aminocyclopropanecarboxylic Acid CAS#22059-21-8
Shortened to ACC, 1-aminocyclopropanecarboxylic acid falls under the category of cyclic non-protein amino acids. This natural compound can be detected in many fleshy fruits including apples and pears. Plant tissues generate the substance based on methionine resources. After its generation, a set of enzyme-driven chemical transformations turn ACC into plant ethylene.
More specifically, relevant catalytic enzymes convert S-adenosylmethionine (SAM) into this cyclic amino-acid monomer. It acts as the vital biosynthetic precursor and takes part in ethylene production which governs multiple plant physiological activities.
