  <name>Methylmalonic acid</name>
  <description>Methylmalonic acid, also known as 2-methylmalonate or methyl-propanedioate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Methylmalonic acid exists as a solid, very hydrophobic, practically insoluble (in water), and relatively neutral molecule. Methylmalonic acid exists in all living species, ranging from bacteria to humans. In cattle, methylmalonic acid is involved in the metabolic pathway called the vitamin K metabolism pathway. Methylmalonic acid is a potentially toxic compound. Methylmalonic acid has been found to be associated with several diseases known as eosinophilic esophagitis, combined malonic and methylmalonic aciduria, alzheimer's disease, and methylmalonic aciduria mitochondrial encephelopathy leigh-like; also methylmalonic acid has been linked to the inborn metabolic disorders including vitamin B12 deficiency.</description>
