Phospholipid Metabolism

Phospholipids are a class of lipids that are important components of animal cell membranes, influencing the conformation and function of membrane-bound receptors and ion channels. Phospholipids also affect cell function by serving as second messengers and as precursors for prostaglandins. The structure of the phospholipid molecule generally consists of a hydrophilic head (a phosphate group and a glycerol) and two hydrophobic tails (two chains of fatty acid). Cholesterol molecules are often found within the spaces of the phospholipid.

Two important phospholipids are phosphatidylcholine and phosphatidylserine. Phospholipids are found in high concentrations in the membrane of practically every cell of the body, including the myelin sheaths of neurons. They help neurons communicate and influence how well their receptors function. Phospholipids are also important components of lung surfactant.


SA offers a number of products for the study of Phospholipid Metabolism - Kinase Regulators, Phospholipase Activators, Phospholipase Inhibitors, and Phospholipases.
