At cysteine, aldehyde can oxidize to carboxylic acid using two NAD+ {oxidation, carbohydrate}. R-CHO -> R-CHOH-S-cys + 2 NAD+ -> R-CO-S-cys + 2 NADH -> R-COOH. Sugars can oxidize to makes acids: ascorbic acid, gluconic acid, uronic acid, and phytic acid {oxidized sugar}. Sugar aldehyde or ketone group can reduce to alcohol group to make glycerol, inositol, sorbital, and mannitol reduced sugars. Glycerol and inositol bind fatty acids. Sorbital and mannitol are food additives.
