Amino Acids, Proteins and Porphyrins
Glutamate is not a precursor of:
In kidneys NH3 is synthesized as:
a. Glutamine --------------→ Glutamate + NH4+ (Principal path.)
b. Glutamate.-------------→α-KG + NH4+
Glutathione: is a Tripeptide→-Glutamyl — cysteinyl-glycine.
Proline→in mammals→proline is formed from glutamate by reversal of the reactions of proline catabolism.
Histidine→essential Amino-acid, not synthesized in body or semi essential amino acid.
