Medium-chain acyl-CoA dehydrogenase deficiency (MCAD deficiency or MCADD) is a disorder of fatty acid oxidation that impairs the body's ability to break down medium-chain fatty acids into acetyl-CoA. The disorder is characterized by hypoglycemia and sudden death without timely intervention, most often brought on by periods of fasting or vomiting.
The medium chain acyl-CoA dehydrogenase (MCAD) is the best known structure of all ACADs, and is the most commonly deficient enzyme within the class that leads to metabolic disorders in animals. [1] This protein is a homotetramer with each subunit containing roughly 400 amino acids and one equivalent of FAD per monomer.
a medium-chain acyl-CoA + electron-transfer flavoprotein a medium-chain trans-2,3-dehydroacyl-CoA + reduced electron-transfer flavoprotein. This enzyme contains FAD as prosthetic group and participates in fatty acid metabolism and PPAR signaling pathway. [9]
ACADM (acyl-Coenzyme A dehydrogenase, C-4 to C-12 straight chain) is a gene that provides instructions for making an enzyme called acyl-coenzyme A dehydrogenase that is important for breaking down (degrading) a certain group of fats called medium-chain fatty acids.
A rare disease called multiple acyl-CoA dehydrogenase deficiency (MADD) [13] is a fatty acid metabolism disorder. Acyl-CoA is important because this enzyme helps make Acyl-CoA from free fatty acids, and this activates the fatty acid to be metabolized.

Numerous genetic disorders are caused by errors in fatty acid metabolism.These disorders may be described as fatty oxidation disorders or as a lipid storage disorders, and are any one of several inborn errors of metabolism that result from enzyme defects affecting the ability of the body to oxidize fatty acids in order to produce energy within muscles, liver, and other cell types.
ACADL is a gene that encodes LCAD - acyl-CoA dehydrogenase, long chain - which is a member of the acyl-CoA dehydrogenase family. The acyl-CoA dehydrogenase family is primarily responsible for beta-oxidation of fatty acids within the mitochondria. LCAD dysfunction is associated with lowered fatty acid oxidation capacity and decreased heat ...
