Lipolysis / l ɪ ˈ p ɒ l ɪ s ɪ s / is the metabolic pathway through which lipid triglycerides are hydrolyzed into a glycerol and free fatty acids. It is used to mobilize stored energy during fasting or exercise , and usually occurs in fat adipocytes .
In humans, the healthy amount of white adipose tissue varies with age, but composes between 6–25% of body weight in adult men and 14–35% in adult women. [ 1 ] [ additional citation(s) needed ] Its cells contain a single large fat droplet , which forces the nucleus to be squeezed into a thin rim at the periphery.
The Basics of Losing Weight After 40. Losing weight can be challenging at the best of times. But after the big 4-0, a few more challenges pop up, making weight gain common and weight loss harder.
A diagrammatic illustration of the process of lipolysis (in a fat cell) induced by high epinephrine and low insulin levels in the blood. Epinephrine binds to a beta-adrenergic receptor in the cell membrane of the adipocyte, which causes cAMP to be generated inside the cell.

Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [1] [2] It also contains the stromal vascular fraction (SVF) of cells including preadipocytes, fibroblasts, vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages.
Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6] Since lipids are hydrophobic molecules, they need to be solubilized before their metabolism can begin. Lipid metabolism often begins with hydrolysis, [7] which occurs with the help of various enzymes in the digestive system. [2]
Until recently, inspiring representations of women over 40 in fiction or on screen were thin on the ground. But the middle-aged heroine is having a moment – and, far from glossing over her age ...
