Summary Introduction
To determine: The amino acid from which the melatonin is derived and the modifications that occurred during this conversion.
Concept introduction:
A hormone that plays an important role in sleep is melatonin (N-acetyl-5-methoxy tryptamine). It is produced by the pineal gland. It has many significant effects in integrating photoperiod and affecting the circadian rhythms.
