(a) Tryptophan is a precursor to neurotransmitters serotonin and melatonin. Thyroxine (3,5,3',5'-tetraiodothyronine) is produced by follicular cells of the thyroid gland. It is produced as the precursor thyroglobulin. Estrogen is biosynthesized from progesterone (arrived at in two steps from cholesterol, via intermediate pregnenolone). Cortisone is one of several end-products of a process called steroidogenesis. Cortisol is produced in the adrenal cortex of kidney.

Tryptophan is an essential amino acid, which means it cannot be synthesized by the body and must be obtained through the diet. It is a precursor for the synthesis of several important molecules in the body, including melatonin and serotonin.
Melatonin and Serotonin
Melatonin is a hormone that is involved in regulating the sleep-wake cycle. It is synthesized in the pineal gland of the brain from serotonin. Tryptophan is a precursor for serotonin, which is converted to melatonin in the pineal gland.
Serotonin is a neurotransmitter that is involved in regulating mood, appetite, and sleep. It is synthesized in the brain from tryptophan. Tryptophan is transported across the blood-brain barrier into the brain, where it is converted to serotonin.
In summary, tryptophan is a precursor for the synthesis of both serotonin and melatonin, two important molecules involved in regulating mood and sleep.
Other options
Thyroxine and Triiodothyronine are thyroid hormones that are synthesized from the amino acid tyrosine, not tryptophan.
Estrogen and progesterone are steroid hormones that are synthesized from cholesterol, not amino acids.
Cortisol and cortisone are steroid hormones that are synthesized from cholesterol, not amino acids.
