MICROANATOMY

Detailed explanation-1: -Adipocytes are specialized cells in storing energy as neutral fatty acids when the energy balance is positive. Unilocular means that the majority of the cell cytoplasm is occupied by a very large lipid droplet. Most adipocytes of the body are white adipocytes.

Detailed explanation-2: -Although the majority of cells may content lipid droplets, adipocytes are animal cells specialized in producing and keeping lipid drops. There are two main types of adipocytes. Unilocular adipocytes (white fat cells) contain one very large lipid droplet that occupies most of the cytoplasm.

Detailed explanation-3: -Lipid droplets, also referred to as lipid bodies, oil bodies or adiposomes, are lipid-rich cellular organelles that regulate the storage and hydrolysis of neutral lipids and are found largely in the adipose tissue. They also serve as a reservoir for cholesterol and acyl-glycerols for membrane formation and maintenance.

Detailed explanation-4: -Lipids are mainly stored in white adipocytes by esterification of energy-rich fatty acids and glycerol to form triglycerides. Fatty acids are released from fat cells into the blood stream through triglyceride hydrolysis (lipolysis).
