NEET PG DENTAL EXAM

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: -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-3: -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).

Detailed explanation-4: -Lipid droplets are cytosolic fat storage organelles present in most eukaryotic cells. Long regarded merely as inert fat reservoirs, they are now emerging as major regulators of cellular metabolism. They act as hubs that coordinate the pathways of lipid uptake, distribution, storage, and use in the cell.
