Question

The derivative hormone of amino acid is
(A) Insulin
(B) Oxytocin
(C) Erythropoietin
(D) Thyroxine

Answer 1

Hint: If a hormone is obtained from amino acids, its chemical name ends in-ine.

Complete answer:To solve this question, first, we should learn about hormones. Nature uses a diverse spectrum of proteins as hormones, and knowledge of a hormone's basic structure imparts considerable knowledge of its receptor and action mechanism.

Now lets us find the solution from the given options-
1. Peptide and protein hormones, naturally, are translation products. Insulin-like growth factor-1 attaches to one of a variety of proteins. So, Insulin is an incorrect answer.
2. Oxytocin is a hormone of the peptides and a neuropeptide. Normally it is formed in the hypothalamus and produced by the posterior pituitary. So, Oxytocin is an incorrect answer.
3. Erythropoietin, also recognized as hematopoietin or hemopoietin, is a cytokine glycoprotein naturally produced primarily by the kidney in response to cellular hypoxia; it induces the development of red blood cells (erythropoiesis) in the bone marrow;. So, Erythropoietin is an incorrect answer.

The hormone deriving from amino acid is thyroxine. Tyrosine is an amino acid and the thyroid hormones (T3) and their prohormone (T4) are thyroid-generated hormones that are mainly responsible for metabolism control. So, Thyroxine is the correct answer.

Thus, option D is the correct answer i.e. Thyroxine

Note:The hormones derived from amino acids are small molecules originating from the amino acids tyrosine and tryptophan.
