Microsomal hydroxylation of decane
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1969Abstract 1. 1. Aliphatic hydrocarbons (hexane, octane and decane) were oxidized in the microsomes from the livers of mouse, rat, rabbit, beef, pigeon and chick embryo. 2. 2. The oxidation of decane by mouse liver microsomes required NADPH and O 2 .

Deoxyribonucleic acid has been isolated from the microsomes of mouse liver homogenates under conditions designed to prevent or greatly reduce mitochondrial and nuclear contamination. The DNA rapidly incorporates tritiated thymidine, and this, together with its reannealing characteristics after thermal denaturation, shows that it is not mitochondrial or

Lipid Peroxidation of Rat‐Liver Microsomes [PDF]
European Journal of Biochemistry, 1973 Rat liver microsomes were peroxidized in vitro and chemical, physical and morphological changes in the membrane were related to the effects on certain membrane‐bound microsomal enzymes.With increasing peroxidation, microsomal phospholipids revealed decreasing concentrations of 20:4 and 22:6 fatty acids.

[30] Microsomal lipid peroxidation
1978Publisher Summary This chapter discusses microsomal lipid peroxidation. Lipid peroxidation is a complex process known to occur in both plants and animals. It involves the formation and propagation of lipid radicals, the uptake of oxygen, a rearrangement of the double bonds in unsaturated lipids, and the eventual destruction of membrane lipids ...

Pieces of liver (in vitro ischemia) and isolated microsomes were subjected to incubation at 4 degrees C and 37 degrees C for various time intervals. The effects on microsomal protein, phospholipids, and cholesterol and on microsomal phosphatases and electron transport enzymes were followed as a functional of time and temperature.

The spatial relationships of the myriad enzymes concerned in cell metabolism have assumed great significance in our efforts to understand the intergrated economy of the plant cell. During investigations into the intracellular distribution of enzymes, the biochemical activities of the mitochondria have been widely studied.

[6] Preparation of microsomes with calcium
1978Publisher Summary This chapter focuses on the preparation of microsomes with calcium. Isolation of the microsomal fraction of the hepatic cell employs a procedure of differential ultracentrifugation. This method is developed for mammalian liver tissue, but also employed to obtain microsomal fractions from a variety of tissues, such as lung, kidney ...

Characteristics of b-type cytochromes in brain microsomes: Comparison with liver microsomes
Archives of Biochemistry and Biophysics, 1984Biochemical aspects of b-type cytochromes in swine cerebral microsomes were different from those of cytochrome b5 in liver microsomes, as well as the difference in absorption spectra. First, the kinetic constants, Km and Vmax, in rotenone-insensitive NADH-cytochrome c reductase activity were different from those of liver microsomes, and the activity of

Non-Enzymic Lipid Peroxidation in Microsomes and Microsomal Phospholipids Induced by Anthracyclines
Free Radical Research Communications, 1986The stimulation of non-enzymic lipid peroxidation by doxorubicin, daunorubicin and 7 derivatives was investigated in extracted microsomal phospholipids and in intact microsomes. Evidence was obtained for the necessity of a free amino-sugar moiety for a stimulative effect on lipid peroxidation.

The effect of deoxycholate on rat brain microsomes and microsomal (Na+K+)-ATPase
Brain Research, 1973Abstract Under carefully controlled conditions for the treatment of rat brain microsomal membranes with deoxycholate, a marked increase in the activities of (Na + K + )-ATPase and total ATPase were observed. The relationship between the increase in enzymic activities and the amount of protein rendered soluble could not explain the observed ...
