White adipocytes are specialized cells that store energy in the form of fat. They are a type of fat cell found in adipose tissue, which is the body's primary energy reserve. These cells have a large lipid droplet that occupies most of their volume, allowing them to store excess calories from food. White adipocytes also play a role in regulating metabolism and hormone production. In addition to energy storage, white adipocytes help insulate the body and protect vital organs. They release hormones such as leptin, which helps regulate appetite and energy balance. An excess of white adipocytes can lead to obesity and related health issues, making their function important for overall health.
