1. Caracterização parcial de nutrientes da rúcula (Eruca sativa L.) e o efeito do tratamento térmico sobre a atividade de lipoxidase
Resumo O objetivo deste trabalho foi determinar alguns nutrientes essenciais da rúcula e o efeito do tratamento térmico na atividade da lipoxidase. Foram, assim, determinados: proteínas, lipídios, carboidratos, fibras, cinzas, composição de ácidos graxos, α-tocoferol e carotenoides. Devido à sua importância na degradação lipídica, a atividade d

5. Stimulation of human platelet guanylate cyclase by unsaturated fatty acid peroxides.
Guanylate cyclase [GTP pyrophosphate-lyase (cyclizing), EC 4.6.1.2] activity of human platelet homogenates was stimulated by the addition of phospholipase A2 or unsaturated fatty acids such as oleic, vaccenic, linoleic, linolenic, eicosenoic, eicosadienoic, and arachidonic acids. The addition of lipoxidase potentiated the fatty acid-induced stimulation of gu

6. Hydroperoxide Isomerase: A New Enzyme of Lipid Metabolism
An enzyme has been isolated from flaxseed (Linum usitatissimum) which utilizes the product of lipoxidase for its substrate. The enzyme, termed hydroperoxide isomerase, converts the conjugated diene hydroperoxide of linoleic acid to the corresponding monoenoic ketohydroxy fatty acid. The structure of the latter has been determined by ultraviolet, infrared, an

7. Simple and specific test for measuring lipid peroxides in plasma.
The specificity of an iodometric assay for measuring lipid peroxides in lipoproteins was tested, compared with the fluorimetric thiobarbituric acid assay, and adopted for detecting lipid peroxide in plasma samples. Oxidation of low density lipoproteins in vitro by Cu2+, lipoxidase, and phagocytosing polymorphonuclear leucocytes was sensitively detected by th
