Which of the following hormones is a derivative of an amino acid?

Epinephrine, also known as adrenaline, is not an amino acid derivative. It is a catecholamine, which is a type of organic compound derived from the amino acid tyrosine. Catecholamines are synthesised in the body from the amino acid tyrosine through a series of enzymatic reactions. Epinephrine is produced in the adrenal glands, which are located on top of the kidneys, and it plays a crucial role in the body's response to stress, increasing heart rate, dilating airways, and mobilising energy stores, among other effects.
