Metabolism of Histidine and Lysine || Metabolism of Basic Amino Acids || NEET PG || Biochemistry

This video is on the metabolism of Histidine and Lysine which are basic amino acid.

Histidine is basic and nutritionally semi-essential amino acid

Histidine has an imidazole ring.

Its pK value is 6.1; and hence in proteins, histidine is responsible for the maximum buffering action
Importance of Histidine
1.Synthesis of histamine –
- Mediator of allergic reactions
- Potent vasodilator
- Increases the secretion of gastric juice

Metabolism of Lysine

Lysine is a nutritionally essential amino acid.

Lysine is ketogenic amino acid.

Its deficient in cereals

It contains two amino groups, neither of which can undergo direct transamination.
