Question
Chapter 25.2, Problem 25.2KCP
Interpretation Introduction
Interpretation:
Class of enzyme that catalyzes the two steps in the conversion of tryptophan to serotonin has to be identified.
Concept introduction:
- Neurotransmitters are chemical messenger of the nervous systems where the transmission of nerve signal takes place.
- Serotonin is a brain neuro transmitter.
- Tryptophan is a non-polar amino acid that has indole as the side chain.
- Enzymes are the biological catalyst.
- Class of enzymes include
-
- 1. Oxidoreductases
- 2. Transferases
- 3. Hydrolases
- 4. Lyases
- 5. Isomerase
- 6. Ligases.
- Tryptophan hydroxylase belongs to the class of oxidoreductase.
