Why Do We Really Need Vitamins?
Figure 1: This figure illustrates the interaction between an enzyme, a substrate, and a cofactor. The enzyme is glucosidase, which catalyzes the breakdown of its substrate maltose to glucose. This reaction is facilitated by the cofactor nicotinamide adenine dinucleotide (NAD+). This cofactor is derived from vitamin B3.3 The images above (of NAD+ and glucosidase) have …
