FunctionAmino acidAdditional information
Directly INCORPORATED during de novo synthesis of purines
Condenses with succinyl CoA in the first step of heme biosynthesis

Source of amino groups in transamination reactions
Reacts with ATP to form SAM, an important source of methyl groups for methylation reactions
Formed in mitochondria during urea cycle by transfer of carbamoyl group
Amino group donor in amino sugar biosynthesis
Precursor to the catecholamine and thyroid hormones
Precursor to the neurotransmitter serotonin
Amino group donor in purine biosynthesis (does NOT get incorporated!)
Decarboxylated to form histamine
Amino acid neurotransmitter with the LARGER molecular mass - primary excitatory neurotransmitter in the CNS
Source of GABA, the primary inhibitory neurotransmitter in the CNS
FunctionAmino acidAdditional information
Amino acid neurotransmitter with the SMALLER molecular mass
