3-Carboxy-3-hydroxy-4-methylpentanoate

Description

2-Isopropylmalic acid (CAS: 3237-44-3), also known as 3-carboxy-3-hydroxyisocaproic acid, belongs to the class of organic compounds known as hydroxy fatty acids. These are fatty acids in which the chain bears a hydroxyl group. 2-Isopropylmalic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 2-Isopropylmalic acid is an alpha-hydroxy organic acid regularly occurring in the urine of healthy individuals (PMID: 2338430 , 544608 ), and in hemofiltrates (PMID: 7251751 ). 2-Isopropylmalic acid is elevated during fasting and diabetic ketoacidosis (PMID: 1591279 ). It is also a metabolite found in Acetobacter (PMID: 6035258 ).
