An example of a nonvitamin coenzyme is S-adenosyl methionine, which transfers a methyl group in bacteria as well as in eukaryotes and archaea. Coenzyme A: Although not used in the electron transport chain, Coenzyme A is a major cofactor which is used to transfer a two carbon unit commonly referred to as the acetyl group.The structure has many common features with NAD+ and FAD in that it has the diphosphate, ribose, and adenine.
