WebMalonyl-CoA is a key intermediary metabolite in fatty acid synthesis. In de novo fatty acid synthesis, malonyl-coenzyme A (CoA) is the substrate that provides the primary carbon source for the formation of palmitate (C16) catalyzed by fatty acid synthase (FASN). WebMalonyl-CoA (3C) In fatty acid synthesis, Acetyl-CoA (2C) and Malonyl-CoA (3C) join to make a 4 carbon molecule. Where does the other carbon molecule go? Decarboxylation removes one carbon molecule as CO2 After creating our 4 carbon material from Malonyl-CoA and Acetyl-CoA, what happens next? We continue by adding TWO carbons at a time. gpw benchmark regulamin https://bulldogconstr.com
