Question 1

What is the Meaning of Peptide Hormone Degradation?

Accepted Answer

Peptide hormone degradation is the precise biological process by which the body breaks down and inactivates peptide hormones, which are protein-based signaling molecules, after they have exerted their necessary physiological effect. This controlled catabolism is essential for terminating hormonal signaling, maintaining physiological homeostasis, and preventing receptor overstimulation in target tissues. The process involves specific enzymes and cellular pathways that cleave the peptide bonds, ensuring the hormone's half-life and biological activity are tightly regulated within the endocrine system.

Question 2

What is the Origin of Peptide Hormone Degradation?

Accepted Answer

This concept is foundational to endocrinology and protein biochemistry, dating back to the isolation and characterization of the first peptide hormones, such as insulin and growth hormone. The term is derived from the necessity to explain the relatively short half-lives of peptide hormones compared to the more stable steroid hormones. The study of how enzymes like peptidases and proteases specifically recognize and inactivate these signaling molecules is a long-standing and crucial area of endocrine research.

Question 3

What is the Mechanism of Peptide Hormone Degradation?

Accepted Answer

The degradation primarily occurs through the action of various proteases and peptidases located on the cell surface, in the circulation, and within lysosomes after receptor-mediated endocytosis. For example, dipeptidyl peptidase-4 rapidly cleaves and inactivates certain gut peptides to regulate glucose homeostasis. Once cleaved, the peptide fragments lose their ability to bind to their cognate receptors, and the resulting amino acids are efficiently recycled by the cell. This rapid, enzymatic breakdown ensures that hormonal signals are transient and precisely controlled, allowing the endocrine system to respond quickly to changing physiological demands.
