Niacin molecular weight

Most of the electrons removed from fuels during energy metabolism are transferred via nicotinamide adenine dmucleotide (NAD). NAD collects electrons from many different energy fuels in reactions catalyzed by specific enzymes. These enzymes are dehydrogenases. Reduced NAD, in turn, shuttles the electrons to the respiratory chain. Flavin adenine dinudeohde (FAD) also acts as an electron shuttle. In each reaction involving NAD (or FAD), two electrons are transferred that is, two electrons are carried or shuttled. NAD and PAID are small molecules with molecular weights of 663 and 7S5 and a re manufactured in the body from the vitamins niacin and riboflavin, respectively. These molecules are called N.A.D. and F.A.D., not nad" o r "fad."... 

In contrast, a number of studies showed worsening of insulin sensitivity with niacin treatment. For instance, in randomised double-blind placebo-controlled treatment study in which 20 men with the metabolic syndrome received 1500 mg niacin for six weeks, low- and medium-molecular weight adiponectin increased by 35% and 33%, respectively, but high molecular weight (HMW)...
