Phospholipase A2 ( EC 3.1.1.4 , PLA2 ) belongs to a family of enzymes that catalyze the hydrolysis of an ester linkage in the sn-2 position of glycerophospholipids free fatty acids ( TC) , including arachidonic acid (AA ) and lysophospholipids . These compounds may act as secondary messengers in the central nervous system ( CNS). Under physiological conditions, cPLA2 is responsible for the level of KT in cell membranes , stability and fluidity of the membranes and transport processes .

This paper describes the structure of the gene superoxide dismutase (SOD) and presents the latest news on their expression, with particular emphasis on mechanisms of regulation of gene expression of MnSOD in the state of oxidative stress.
