  <name>Isobutyrylcarnitine</name>
  <description>Isobutyrylcarnitine belongs to the class of organic compounds known as acyl carnitines. These are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. Isobutyrylcarnitine is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa).</description>
