The fatty acid pool in adipose tissue.

Adipose tissue, stimulated by epinephrine (1, 2) or other hormones (3-6), discharges fatty acids into an incubation medium. It also can take up acids and esterify them (7). The possibility thus arises that the opposing effects, uptake and lipolysis, might be the forward and reverse aspects of a single process (8, 9). I f this is the case, the quantity of fatty acids taken up and the quantity re...

Fat oxidation, lipolysis, and free fatty acid cycling in obesity-prone and obesity-resistant rats.

Defects in fat metabolism may contribute to the development of obesity, but what these defects are and where they occur in the feeding/fasting cycle are unknown. In the present study, basal fat metabolism was characterized using a high-fat diet (HFD)-induced model of obesity development. Male rats consumed a HFD (45% fat, 35% carbohydrate) ad libitum for either 1 or 5 wk (HFD1 or HFD5). After 1...

Regulation of free fatty acid metabolism by insulin in humans: role of lipolysis and reesterification.

The regulation of lipolysis, free fatty acid appearance into plasma (FFA R(a)), an FFA reesterification and oxidation were examined in seven healthy humans infused intravenously with insulin at rates of 4, 8, 25, and 400 mU.m-2.min-1. Glycerol and FFA R(a) were determined by isotope dilution methods, and FFA oxidation was calculated by indirect calorimetry or by measurement of expired 14CO2 fro...

Free fatty acid regulation of glucose-dependent intrinsic oscillatory lipolysis in perifused isolated rat adipocytes.

Free fatty acids (FFAs) and glycerol oscillate in plasma. This study examined intrinsic lipolytic oscillations within adipocytes. Rat adipocytes were perifused with Krebs-Ringer bicarbonate buffer: 1) +/- 2 mmol/l glucose; 2) +1 micromol/l isoproterenol +/- 2 mmol/l glucose; 3) + increasing oleate; and 4) + increasing percent BSA. At 2 mmol/l glucose, there were 9 +/- 1 glycerol, FFAs, and lact...
