1 point Nicotinamide adenine dinucleotide (NAD+) is an essential cofactor for many metabolic reactions. Lack of the precursor to NAD+, niacin, results in the human disease called pellagra, thus humans have evolved salvage pathways to breakdown and re-synthesize NAD+ when needed. Below is the chemical structure of NAD+. Enzymes catalyze reactions in parts of the protein called an active site. This portion of the protein forms favorable weak interactions with the substrate and stabilize the transition state, which is crucial...
