Kroppsfettvävnad

Kroppsfettvävnad, also known as adipose tissue, is a type of connective tissue that stores energy in the form of fat. It is found throughout the body, with the largest deposits being in the subcutaneous layer just beneath the skin. Adipose tissue serves multiple functions, including energy storage, insulation, cushioning, and hormone production.

There are two main types of adipose tissue: white adipose tissue and brown adipose tissue. White adipose tissue is the most common type and is responsible for storing excess energy. It is composed of adipocytes, which are specialized cells that store fat droplets. Brown adipose tissue, on the other hand, is found primarily in infants and hibernating animals. It contains brown adipocytes, which are capable of producing heat through a process called non-shivering thermogenesis.

Adipose tissue plays a crucial role in metabolism and energy homeostasis. It releases fatty acids into the bloodstream, which can be used by other tissues for energy when needed. Additionally, adipose tissue produces hormones such as leptin and adiponectin, which regulate appetite and insulin sensitivity.

The amount of adipose tissue in the body can vary greatly among individuals and is influenced by factors such as genetics, diet, and physical activity. Excessive accumulation of adipose tissue can lead to obesity, which is associated with an increased risk of various health conditions, including type 2 diabetes, cardiovascular disease, and certain cancers. Conversely, insufficient adipose tissue can result in conditions such as lipodystrophy, where fat is not properly distributed throughout the body.
