What is a fat tissue cell called?
Lying three layers deep under the skin, the adipose tissue is composed of a loose collection of specialized cells, called adipocytes, embedded in a mesh of collagen fibers. Its main role in the body is function as a fuel tank for the storage of lipids and triglycerides.
What type of tissue cells store fat?
Adipose tissue is a specialized connective tissue consisting of lipid-rich cells called adipocytes. As it comprises about 20-25% of total body weight in healthy individuals, the main function of adipose tissue is to store energy in the form of lipids (fat).
What is body fat made of?
Fat in the body is in the form of triglycerides. Triglycerides (TG) are made up of three free fatty acid (FFA) molecules held together by a molecule of glycerol (not a fat but a type of alcohol) (Brown, Miller, and Eason 2006) (figure 1). Most of the body’s fat is stored in the adipocytes.
What are white fat cells?
White fat cells are typically round cells of variable sizes with a single, large, lipid droplet. These droplets can be converted to fatty acids during starvation or when energy demands increase. Fatty acids are the building blocks of fats which can be absorbed into the blood.
Do fat cells have a nucleus?
Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule.
Is adipose tissue a connective tissue?
adipose tissue, or fatty tissue, connective tissue consisting mainly of fat cells (adipose cells, or adipocytes), specialized to synthesize and contain large globules of fat, within a structural network of fibres.
Do fat cells have Golgi apparatus?
The Golgi complex of the adipose cells was small and the endoplasmic reticulum almost entirely absent. The significance of the poor development of these organelles is discussed in relation to current concepts of their function.
Is white adipose tissue fat?
White adipose tissue (WAT) or white fat is one of the two types of adipose tissue found in mammals. Its cells contain a single large fat droplet, which forces the nucleus to be squeezed into a thin rim at the periphery. They have receptors for insulin, sex hormones, norepinephrine, and glucocorticoids.
