Study Notes
Significance of Amino Acids
- Amino acids are the building blocks of proteins.
- They also play a variety of other roles in the body.
Biological Functions of Amino Acids
- Tyrosine is involved in the synthesis of hormones such as thyroid hormones (T3, T4), epinephrine and norepinephrine, and the pigment melanin.
- Tryptophan is a precursor for serotonin and vitamin B3 (niacin).
- Histidine can be converted to histamine.
- Glycine is used in the synthesis of heme.
- Glutamic acid is the precursor for gamma amino butyric acid (GABA).
- Glycine, arginine and methionine are involved in the synthesis of creatine.
- Glycine and cysteine are involved in the synthesis of bile salts.
- Glutamate, cysteine and glycine are involved in the synthesis of glutathione.
- Aspartate and glutamine are used in the synthesis of pyrimidines.
- Glycine, aspartic acid, glutamine and serine are used in the synthesis of purines.
