white adipose cell

White adipose cells are specialized connective tissue cells that synthesize and store large amounts of fat, primarily in the form of triglycerides. These cells contain a small amount of cytoplasm and have flattened, non-central nuclei. The fat stored in these cells can come from dietary sources or be produced by the body from carbohydrates and proteins.12

White adipose tissue, composed of these cells, serves as an energy reserve, releasing fatty acids for use by other tissues during periods of energy expenditure or fasting. It also provides insulation and acts as padding between organs. White adipose cells can also synthesize and secrete hormones like leptin, which plays a role in regulating metabolism and body weight. The number of adipose cells in adults is relatively stable, with fat storage occurring through the expansion of existing cells.12
