WebbIn bimolecular reduction, brought about by an active metal such as sodium (Na) or magnesium (Mg), two molecules of an aldehyde combine to give (after hydrolysis) a compound with ―OH groups on adjacent carbons; e.g., 2RCHO → RCH (OH)CH (OH)R. Oxidation reactions of aldehydes are less important than reductions. WebbThis produces an intermediate which can be converted into the final product by boiling it with water.

WebbHnd is unequivocally required for S. fructosivorans growth on ethanol, and we propose that it produces H2 from NADH and reduced ferredoxin generated by an alcohol dehydrogenase and an aldehyde ferredoxin oxidoreductase catalyzing the conversion of ethanol into acetate. The produced H2 could then be recycled and used for sulfate reduction. Aldehydes participate in many reactions. From the industrial perspective, important reactions are (a) condensations, e.g., to prepare plasticizers and polyols, and (b) reduction to produce alcohols, especially "oxo-alcohols". From the biological perspective, the key reactions involve addition of nucleophiles to the formyl carbon in the formation of imines (oxidative deamination) and hemiacetals (structures of aldose sugars).
