We studied the effect of variable isolated fat cell concentrations (from 0.17 to 1.25 x 10(6) cells/ml) on rate and pattern of basal and insulin-stimulated glucose metabolism by rat epididymal fat cells. Cell concentration did not affect total glucose utilization, but high cell concentrations increased the absolute and relative conversion of glucose to CO2 and glyceride-fatty acids by two- to t...

Lipogenesis from glucose and lipolysis in human omental and subcutaneous fat cells were studied as functions of adipose cell size and number in adult females. Since subcutaneous fat cells were larger than those prepared from the greater omentum, a comparison could be made of the metabolism of different sizes of cells within individual subjects. Rates per cell of glyceride-glycerol and glyceride...

The presence of mycotoxins in feed has the potential to cause significant detriment animal and human health, even severe economic implications. Previous studies on effects mainly focused addition commercially available into feeds animals. In present study, corn meal cottonseed were kept warm humid conditions allow for produced then used substitute 50% 100% normal diets lactating cows 14 days. r...

The pathways of glycerol-3-phosphate (G3P) generation for glyceride synthesis were examined in precision-cut liver slices of fasted and diabetic rats. The incorporation of 5 mM [U-(14)C]glucose into glyceride-glycerol, used to evaluate G3P generation via glycolysis, was reduced by approximately 26-36% in liver slices of fasted and diabetic rats. The glycolytic flux was reduced by approximately ...

This report describes a study of serum total cholesterol, free cholesterol, glyceride glycerol, total phospholipids, and uric acid in human twins and is presented in three sections. Section 1 presents evidence that interpair variance of free cholesterol, total cholesterol, total phospholipids, glyceride glycerol, and uric acid are significantly greater in dizygotic than monozygotic twins. Twins...

In order to study the quantitative relationship between fatty acid synthesis and pentose phosphate-cycle activity under different hormonal and dietary conditions affecting the extent of glucose uptake, cells isolated from rat epididymal adipose tissue were incubated in bicarbonate buffer containing [U-14C]-, [1-14C]or [6-14C]-glucose. From the amount of glucose taken up, the production of lacta...

Serum cholesterol, serum glyceride, blood glucose, relative weight, physical activity, percent calories from fat, percent calories from carbohydrate, and polyunsaturated/saturated fatty acid (P/S) ratio were determined in 1780 rural and 4023 urban fasting men aged 45-64 years being followed prospectively to ascertain reasons for the low prevalence of coronary heart disease mortality in Puerto R...

The effect of castration and administration of testosterone propionate (TP) has been studied in mature monkeys in relation to prostatic and seminal vesicular lipids to castrates on prostatic and seminal vesicular lipids were studied in mature monkeys. Castration decreased prostatic total lipid, total phospholipids and total glyceride glycerols. Among neutral lipid classes only diacyl glycerol w...

The synthesis and breakdown of triglycerides in adipose tissue and muscle is a crucial element of energy metabolism because it ensures that adequate fuel is available during starvation. Triglyceride turnover determines the availability of fatty acids for utilization by mammalian tissues, and any dysfunction in this process can lead to alterations in glucose metabolism, insulin resistance and ty...
