Can Fish Synthesize Histidine?
Can Fish Synthesize Histidine? l-Histidine is an essential amino acid that is not synthesized de novo in humans. Humans and other animals must ingest histidine or histidine-containing proteins. The biosynthesis of histidine has been widely studied in prokaryotes such as E. coli. What is histidine synthesized from? Histidine is synthesized in nine steps (Figure 9).
