Carboxylic derivatives are described as compounds that can be converted to carboxylic acids via simple acidic or. basic hydrolysis. The most important acid derivatives are esters, amides and nitriles, although acid halides and anhydrides are also. derivatives (really activated forms of a carboxylic acid).
NAD+ and NADP+, coenzymes that function in oxidation-reduction reactions, are metabolites of ATP. The first step in the synthesis of nicotinamide adenine dinucleotide (NAD+) is the formation of nicotinate ribonucleotide from nicotinate and PRPP. Nicotinate (also called niacin or vitamin B6) is derived from tryptophan.
