Answer 2

Explanation:

Melatonin, a derivative of the amino acid tryptophan, is produced in humans, other mammals, birds, reptiles, and amphibians. In humans, melatonin plays an important role in the regulation of sleep cycles (i.e., circadian rhythm). Its production is influenced by the detection of light and dark by the retina of the eye.
