Structure and Biosynthesis of First Messengers,the first messengers are related to those common metabolites, and the metabolic pathways which interconvert them. The structure and synthesis of peptide messengers exhibits several features which are rather unique and sets them apart from the synthesis of other proteins, and they will be discussed separately at the end of the chapter.作者: 極小量 時間: 2025-3-23 09:15
