The two substrates of this enzyme are L-α-glycerophosphoric acid, and oxidised nicotinamide adenine dinucleotide (NAD⁺). Its products are dihydroxyacetonephosphoric acid, reduced NADH, and a proton. The enzyme can also use the alternative cofactor, nicotinamide adenine dinucleotide phosphate.^{[1][2][3][4][5]}

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is sn-glycerol-3-phosphate:NAD(P)⁺ 2-oxidoreductase. Other names in common use include L-glycerol-3-phosphate:NAD(P)⁺ oxidoreductase, glycerol phosphate dehydrogenase (nicotinamide adenine dinucleotide, (phosphate)), glycerol 3-phosphate dehydrogenase (NADP⁺), and glycerol-3-phosphate dehydrogenase [NAD(P)⁺]. This enzyme participates in glycerophospholipid metabolism.
