Abstract
Summary
By means of a titration method for estimation of bacterial growth it was found that growth is proportional to the quantity of nicotinamide present. Nicotinamide is more active than an equivalent amount of either pyridine-containing coenzyme. Hydrolysis increases the activity of the latter, indicating that the function of nicotinamide is not based entirely on synthesis to either of the known coenzymes. A method has been developed for determining nicotinamide and related substances in blood. The values obtained are higher if autoclaved blood is used.
