Catabolic
Catabolic — Relating to metabolic processes that break complex molecules into simpler ones, releasing energy. Proteolysis is a catabolic process.
What Does Catabolic Mean?
Catabolic refers to metabolic processes that break down complex molecules into simpler ones, releasing energy. Peptide catabolism involves proteolytic degradation into amino acids that are either recycled for new protein synthesis or further catabolized for energy. Catabolic conditions (stress, disease, aging) increase peptide hormone degradation and muscle protein breakdown.
Context
- Catabolic state: Elevated cortisol, reduced GH/IGF-1. Muscle wasting, poor wound healing
- Anti-catabolic peptides: GH secretagogues (ipamorelin, CJC-1295) shift balance toward anabolic state
- Peptide catabolism: Circulating peptides degraded by plasma proteases within minutes to hours
