* '''ALDH class 3''' is found in tumors, stomach and cornea. '''ALDH3A1''' is soluble and has substrate specificity to bulky aromatic aldehydes. '''ALDH3A2''' is a fatty ALDH (FALDH). FALDH was found to have an additional gatekeeper helix at the substrate funnel entrance that is shaping the enzymes substrate specificity. <ref>Keller, Markus A.; Zander, Ulrich; Fuchs, Julian E.; Kreutz, Christoph; Watschinger, Katrin et al.

| - | * '''Glyceraldehyde-3-phophate (G3P)-ALDH''' is called GAPDH. GADPH catalyzes the reversible oxidative phosphorylation of glyceraldehyde-3-phosphate (G3P) to 1,3-bisphosphoglycerate in the presence of inorganic phosphate (Pi) and NAD. The aldehyde of G3P reacts with the cysteine-thiol to form a carboxylic acid in a high energy thioester form. The thioester is attacked by the inorganic phosphate and forms the acyl phosphate. GAPDH is part of the [[glycolysis]] pathway and Calvin cycle. GAPDH contains NAD-dependent and NADPH-dependent enzymes. For the complex of ALDH and nitroglycerine see [[NitroDur]]. | + | * '''Glyceraldehyde-3-phophate (G3P)-ALDH''' is called GAPDH.
