Entry term(s) hidroperóxido de ácido graso

peróxido de lípidos
peróxidos lípidos
Scope note: Peróxidos producidos en presencia de un radical libre por oxidación de ácidos grasos desaturados en la célula en presencia de oxígeno molecular. La formación de peróxidos lípidos da lugar a la destrucción del lípido original lo que lleva a la pérdida de la integridad de las membranas. Causan por lo tanto una variedad de efectos tóxicos in vivo y se considera que su formación es un proceso patológico en los sistemas biológicos. Puede inhibirse su formación por antioxidantes, como vitamina E, separación estructural o una baja tensión de oxígeno.

Scope note: Peroxides produced in the presence of a free radical by the oxidation of unsaturated fatty acids in the cell in the presence of molecular oxygen. The formation of lipid peroxides results in the destruction of the original lipid leading to the loss of integrity of the membranes. They therefore cause a variety of toxic effects in vivo and their formation is considered a pathological process in biological systems. Their formation can be inhibited by antioxidants, such as vitamin E, structural separation or low oxygen tension.
