About
胨 (traditional form: 腖) is a phono-semantic compound devised for modern biochemistry. The left-side radical 月 signifies flesh or organic tissue, while the right-side component 东/東 provides the pronunciation dòng. This character translates the scientific term peptone, a water-soluble mixture of polypeptides and amino acids resulting from the partial hydrolysis of protein. Created solely to meet a terminological need in the translation of biochemical sciences, it has no presence in classical literature and is used exclusively in laboratory, nutritional, and medical contexts.
