rasvasolu

Rasvasolu, also known as an adipocyte, is a cell that primarily constitutes adipose tissue, commonly referred to as body fat. These cells are specialized for storing energy in the form of triglycerides, a type of fat. When the body consumes more calories than it expends, these excess calories are converted into triglycerides and stored within the adipocytes. Conversely, when the body needs energy, triglycerides are broken down and released to be used as fuel.

Adipocytes vary in size and appearance depending on their lipid content and functional state. While often associated with energy storage, adipose tissue and its constituent cells also play crucial roles in metabolism, hormone production, and insulation. They secrete various hormones, including leptin, which regulates appetite, and adiponectin, which influences glucose levels and fatty acid breakdown. Furthermore, adipose tissue helps insulate the body, maintaining its temperature, and also cushions vital organs, providing mechanical protection.

There are two main types of adipose tissue: white adipose tissue and brown adipose tissue. White adipose tissue is the most abundant type and is primarily responsible for energy storage. Brown adipose tissue, found in smaller amounts, is specialized for thermogenesis, or heat production, and is particularly important in infants and hibernating animals. The differentiation and function of rasvasolu are influenced by factors such as diet, genetics, and hormonal signals.
