Description | 2-Methylacetoacetic acid, also known as 2-methyl-3-oxo-butyric acid or 2-acetylpropionic acid, belongs to the class of organic compounds known as short-chain keto acids and derivatives. These are keto acids with an alkyl chain the contains less than 6 carbon atoms. 2-Methylacetoacetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Cholesteryl acetate is found in Baccharoides anthelmintica, Cajanus cajan, Digitalis purpurea, Dioscorea polystachya, Dolichousnea longissima, Heteroxenia ghardaqensis, Pyrosoma atlanticum, Wrightia tinctoria and Zea mays. It was first documented in 1996 (PMID: 9001814). 2-Methylacetoacetic acid, with regard to humans, has been linked to the inborn metabolic disorder beta-ketothiolase deficiency (PMID: 14518824) (PMID: 17371050) (PMID: 9744475). |
