the general term is cofactor, but more specifically, if the cofactor is an organic molecule, it is called a coenzyme.
Organic cofactors are often vitamins or are made from vitamins. Many contain the nucleotide adenosine monophosphate (AMP) as part of their structures, such as ATP, coenzyme A, FAD, and NAD+ . This common structure may reflect a common evolutionary origin as part of ribozymes in an ancient RNA world.owever, vitamins do have other functions in the body. Many organic cofactors also contain a nucleotide, such as the electron carriers NAD and FAD, and coenzyme A, which carries acyl groups. Most of these cofactors are found in a huge variety of species, and some are universal to all forms of life.
