cofactors - ANS -a non-protein chemical compound that is required for a
protein's biological activity to happen (i.e. enzymes)
How do simple sugars differ from each other? - ANS -1.) location of
carbonyl groups
2.) number of carbon atoms present
3.) location of hydroxyl (-OH) group- the spatial arrangement of their
atoms
