  Definition: Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others.
  The whole of lipids is the lipidome.
  Lipids are broadly defined as any fat-soluble (lipophilic), naturally-occurring molecule. Lipids are usually defined as hydrophobic or amphipathic biological molecules that will dissolve in organic solvents such as benzene or (...)

• cholesterol
  14 November 2003

  Definition: Cholesterol is an essential sterol lipid component of eukaryotic plasma and organelle membranes. It is particularly abundant in the brain as a major constituent of myelin.
  Together with sphingolipids, cholesterol is enriched in membrane microdomains termed lipid rafts, which function in cholesterol transport, endocytosis and signal transduction.
  Extracellular transport of cholesterol is mediated by ApoE (APOE).
  Cellular cholesterol homeostasis is maintained through activation (...)

• glutamate
  3 May 2004

  Glutamate is a central junction for interchange of amino nitrogen, glutamate facilitates both amino acid synthesis and degradation.
  In the liver, glutamate is the terminus for release of ammonia from amino acids, and the intrahepatic concentration of glutamate modulates the rate of ammonia detoxification into urea.
  In pancreatic beta-cells, oxidation of glutamate mediates amino acid-stimulated insulin secretion.
  In the central nervous system, glutamate serves as an excitatory (...)
