Study Notes
Amino Acid Derivatives
- Histidine undergoes alpha decarboxylation to form Histamine.
Tryptophan Derivatives
- Alpha decarboxylation of Tryptophan produces Tryptamine.
Tyrosine Derivatives
- Alpha decarboxylation of Tyrosine produces Tyramine.
Transamination Reaction
- The reaction involving the transfer of the alpha amino group of an amino acid to form a new amino acid and alpha keto acid is called Transamination.
Neurotransmitters
- Dopamine is a neurotransmitter derived from Tyrosine.
Glutamic Acid Derivatives
- Glutamic acid and NH3 form Glutamine.
Thyroid Hormones
- Thyroxine (T4) is an amino acid derivative and an important thyroid hormone derived from Tyrosine.
Urea Synthesis
- Ornithine is an amino acid derivative essential for urea synthesis.
Allergic Reactions
- Histamine is a mediator of allergic reactions, derived from Histidine.
