PATHOLOGY

Detailed explanation-1: -Therefore, the hormone that is not derived from an amino acid is B) testosterone.

Detailed explanation-2: -Thyroid hormones (THs)–thyroxine (T4) and tri-iodothyronine (T3)–are iodinated derivatives of the amino acid tyrosine, which regulates growth, development and critical metabolic functions.

Detailed explanation-3: -1 Introduction: The thyroid hormone signaling pathway. Thyroid hormones are a class of nuclear hormones that are iodinated tyrosine derivatives that have diverse functions in metabolism, growth, and development.

Detailed explanation-4: -Amino acid derivative hormone is thyroxine. Tyrosine is an amino acid and the thyroid hormones, (T3) and its prohormone, (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism. Was this answer helpful?

Detailed explanation-5: -The TSHB gene of the TSH- subunit was first cloned in 1988 (37) and is located on chromosome 1 (1p13). It encodes a polypeptide chain of 118 amino acids in length without the signal peptide (38).
