Question

A newly discovered hormone contains four amino acids linked together. Under which chemical class would this hormone be classified?

lipid-derived hormone
amino acid-derived hormone
peptide hormone
glycoprotein

Answer 1

A hormone containing four amino acids would be classified as a peptide hormone, which is one of the three main classes of hormones based on chemical structure.

Step-by-step explanation:

A hormone composed of four amino acids linked together would fall under the peptide hormone category. Hormones are generally classified into three main chemical classes based on their structure: lipid-derived hormones, amino acid-derived hormones, and peptide hormones. Specifically, peptide hormones are chains of amino acids and are water soluble. They cannot diffuse across plasma membranes, thus they typically interact with cell surface receptors. This contrasts with lipid-derived hormones, which are water insoluble but can diffuse across plasma membranes, often affecting cell function by interacting with internal receptors.

Answer 2

peptide hormone

Step-by-step explanation:

Peptide hormones is a molecule that contains four amino acids linked together. These hormones are proteins that have endocrine (hormonal) functions. Some create metabolic performance improvements through communication with the body to trigger the release of growth hormone into the blood. When this occurs the benefit shows in our ability to quickly build muscle mass and release stored fat.
