About
The character 肽 is a modern phono-semantic compound created to translate the scientific term "peptide", denoting short chains of amino acids. It combines the semantic radical 月 (flesh/meal), used for organic and biochemical terms, with the phonetic component 太 for pronunciation. As a recent lexical addition driven by advances in chemistry and biology, 肽 appears only in scientific, medical, and nutritional contexts, with no historical usage in classical texts.
