SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionAlpha-Methylisocitric Acid, also known as methylisocitrate, belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. Thus, Alpha-methylisocitric Acid is considered to be a fatty acid lipid molecule. Alpha-Methylisocitric Acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Alpha-Methylisocitric Acid exists in both E. coli (prokaryote) and yeast (eukaryote).
