Crystalline lysoplasmalogen (lysophosphatidal choline): preparation from heart muscle and action on erythrocytes and spermatozoa.
When mammalian spermatozoa are washed free from seminal plasma (and thus from fructose) and incubated as suspensions in Ringer solution they remain motile provided that oxygen is present. An explanation of this behaviour was put forward by Lardy & Phillips (1941a, b), who suggested that in the absence of the seminal sugar [later identified by Mann (1946) as fructose] the spermatozoa of bull and...
متن کاملO-16: Metabolism of Exogenous Fatty Acids, Fatty Acid-Mediated Cholesterol Efflux, PKA and PKC Pathways in Boar Sperm Acrosome Reaction
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
متن کاملUpid Peroxidation in Semen of the Boar
Smutna M., o. Synek: Lipid Peroxidation in Semen of the Boar. Acta vet. Bmo, 48, 1979: 35-43. During the catalyzed aerobic incubation of the complete boar semen malonyldialdehyde (MDA) is produced. MDA is a good indicator of peroxidative decomposition of polyunsaturated fatty acids. Detection of peroxidation products was conducted both by colour reaction with 2-thiobarbituric acid (evidence of ...
متن کاملFatty Acid Composition of Human Follicular Fluid Phospholipids and Fertilization Rate in Assisted Reproductive Techniques
Background: Fatty acids are known to be critically important in multiple biological functions. Phospholipid fatty acids of follicular fluid, an important microenvironment for the development of oocytes, may contribute to the women’s fertility and the efficacy of assisted reproduction techniques. The aim of this study was to investigate the effect of fatty acid composition of follicular fluid ph...
متن کاملLipid composition and metabolism in testicular and ejaculated ram spermatozoa.
1. Spermatozoa collected directly from the testis of the conscious ram contain 25% more phospholipid than ejaculated spermatozoa. The concentration of lecithin, phosphatidylethanolamine and ethanolamine plasmalogen was greater in testicular spermatozoa; little difference was observed in choline plasmalogen. Both types of spermatozoa had significant amounts of cardiolipin and alkyl ether phospho...
