Question

A newly discovered hormone contains a chain of four linked amino acids. Classify this new hormone into one of the following categories.

a) Peptide hormone
b) Steroid hormone
c) Amino acid derivative hormone
d) Nucleotide hormone

Answer 1

The newly discovered hormone, consisting of four amino acids, would be classified as an amino acid-derived hormone.

Step-by-step explanation:

The newly discovered hormone, which contains a chain of four linked amino acids, would be classified into the category of amino acid-derived hormones.

Amino acid-derived hormones are water insoluble and require a cell surface receptor. They include hormones such as epinephrine, thyroxine, and melatonin.

Unlike lipid-derived hormones that can diffuse across plasma membranes, amino acid-derived hormones, such as the newly discovered hormone in question, cannot.
