Description | Methylisocitric acid, also known as alpha-methylisocitrate, belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. Methylisocitric acid exists in all living species, ranging from bacteria to plants to humans. Methylisocitric acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Methylisocitric acid. |
