Amino acid neurotransmitter with the SMALLER molecular mass
Formed in mitochondria during urea cycle by transfer of carbamoyl group
Important component in the urea cycle, formed in cytoplasm alongside urea in final step
Directly INCORPORATED during de novo synthesis of purines
Reactant in ammonia fixation
Decarboxylated to form histamine
One of the three amino acids involved in creatine biosynthesis
Condenses with succinyl CoA in the first step of heme biosynthesis
Yields important intermediate in melanin synthesis
