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.
People who are slim but have hidden pockets of fat within their muscles are at increased risk of deadly heart conditions, new research shows. Researchers looked at 669 women who were being ...
White fat cells secrete many proteins acting as adipokines such as resistin, adiponectin, leptin and apelin. An average human adult has 30 billion fat cells with a weight of 30 lbs or 13.5 kg. If a child or adolescent gains sufficient excess weight, fat cells may increase in absolute number until age twenty-four. [3]
The first and best-characterized family of lipid droplet coat proteins is the perilipin protein family, consisting of five proteins. These include perilipin 1 (PLIN1), perilipin 2 (PLIN2/ ADRP), [11] perilipin 3 (PLIN3/ TIP47), perilipin 4 (PLIN4/ S3-12) and perilipin 5 (PLIN5/ OXPAT/ LSDP5/ MLDP).

Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
3. Sleep Deprivation. There is a link between sleep loss and weight gain. Research shows that people who routinely don’t get enough sleep tend to eat higher-calorie and higher-fat diets.. Not ...
Many types of neutral fats are possible both because of the number and variety of fatty acids that could form part of it and because of the different bonding locations for the fatty acids. An example is a monoglyceride , which has one fatty acid combined with glycerol, a diglyceride , which has two fatty acids combined with glycerol, or a ...
