CatabolicPathwaysforMethionine,Isoleucine,ThreonineandValine

The carbon chains of methionine, isoleucine, threonine and valine are broken down to produce succinyl-CoA, which feeds into the Citric Acid Cycle. Methionine donates its methyl group via S-adenosylmethionine to one of several acceptors and the four remaining carbons are the backbone of pronionyl-CoA that is subsequently converted to succinyl-CoA. The degredation of threonine shown here occurs in humans. A different m......阅读全文
