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.
In the upper body, an increase of adipocyte size correlated with upper-body fat gain; however, the number of fat cells was not significantly changed. In contrast to the upper body fat cell response, the number of lower-body adipocytes did significantly increase during the course of experiment.
It is stored in different depots to gynoid fat: android fat is stored in the lower body and can present a so-called "triangle-shaped" body, while gynoid fat is stored in the upper body and can result in a "apple-shaped" body. Android fat cells are mostly visceral - they are large, deposited deep under the skin and are highly metabolically active.
Males are more susceptible to upper-body fat accumulation, most likely in the belly, due to sex hormone differences. [95] When comparing the body fat of men and women it is seen that men have close to twice the visceral fat as that of pre-menopausal women. [96] [97]
It is the main storage form of glucose in the human body. Glycogen functions as one of three regularly used forms of energy reserves, creatine phosphate being for very short-term, glycogen being for short-term and the triglyceride stores in adipose tissue (i.e., body fat) being for long-term storage.
Chronic high sugar intake causes your body to release a lot of insulin, which can lead to insulin resistance—a condition where cells don't respond well to the insulin and, as the name suggests ...
Here are some reasons to consider reducing your sugar intake, and how to do it. Most people eat too much sugar, but not all sugars are the same. Here are some reasons to consider reducing your ...
In the body, stores of fat are referred to as adipose tissue. In these areas, intracellular triglycerides are stored in cytoplasmic lipid droplets. When lipase enzymes are phosphorylated, they can access lipid droplets and through multiple steps of hydrolysis, breakdown triglycerides into fatty acids and glycerol. Each step of hydrolysis leads ...
