Sigma-Aldrich is a leading Life Science and High Technology company dedicated to providing high-quality, safe and certified flavor ingredients with transparent and easily accessible documentation to customers around the globe. The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. pH Value. Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable organic compound (chemical formula CH 3 CHOHCH 3) with a strong alcoholic odor. Alcohol dehydrogenases (ADH) (EC 1.1.1.1) are a group of dehydrogenase enzymes that occur in many organisms and facilitate the interconversion between alcohols and aldehydes or ketones with the reduction of nicotinamide adenine dinucleotide (NAD +) to NADH.In humans and many other animals, they serve to break down alcohols that otherwise are toxic, and they also participate in L'thylne glycol ou glycol ou encore thane-1,2-diol est le plus simple compos chimique de la famille des glycols. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms.

Acrolein (systematic name: propenal) is the simplest unsaturated aldehyde.It is a colorless liquid with a piercing, acrid smell. Cancer recurrence after surgical resection remains a significant cause of treatment failure. It can be obtained by reduction of glucose, which changes the converted aldehyde group (CHO) to a primary alcohol group (CH 2 OH). Its production generates 1.6 tonnes of CO2 per tonne of ethylene glycol. Preparation.
