Identification
Name:Nicotinic acid
DescriptionNicotinic acid, also known as niacin or vitamin B3, is a derivative of pyridine, with a carboxyl group (COOH) at the 3-position. Other forms of vitamin B3 include the corresponding amide, nicotinamide ("niacinamide"), where the carboxyl group has been replaced by a carboxamide group (CONH2), as well as more complex amides and a variety of esters. The uptake of nicotinic acid by Escherichia coli is dependent on the presence of the enzyme nicotinic acid phosphoribosyl transferase and a source of energy.
