Chemical Information
DescriptionMalonyl-carnitin, also known as d,l-carnitine or carnitine chloride, is a member of the class of compounds known as carnitines. Carnitines are organic compounds containing the quaternary ammonium compound carnitine. Malonyl-carnitin is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Malonyl-carnitin can be synthesized from butyrate. Malonyl-carnitin is also a parent compound for other transformation products, including but not limited to, O-sebacoylcarnitine, O-(4,8-dimethylnonanoyl)carnitine, and O-(11-carboxyundecanoyl)carnitine. Malonyl-carnitin can be found in avocado, which makes malonyl-carnitin a potential biomarker for the consumption of this food product. Malonyl-carnitin can be found primarily in blood.
