Sebacic acid is a saturated, straight-chain naturally occurring dicarboxylic acid with 10 carbon atoms. Sebacic acid is a normal urinary acid. In patients with multiple acyl-CoA-dehydrogenase deficiency (MADD) or glutaric aciduria type II (GAII) are a group of metabolic disorders due to deficiency of either electron transfer flavoprotein or electron transfer flavoprotein ubiquinone oxidoreductase, biochemical data shows an increase in urine sebacic acid excretion. Sebacic acid is a white flake or powdered crystal slightly soluble in water that has been proposed as an alternative energy substrate in total parenteral nutrition. Sebacic Acid was named from the Latin sebaceus (tallow candle) or sebum (tallow) in reference to its use in the manufacture of candles. Sebacic Acid and its derivatives such as azelaic acid have a variety of industrial uses as plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. It is used in the synthesis of polyamide and alkyd resins. It is also
