Zsírraktárak

Zsírraktárak, often translated as "fat depots" or "adipose tissue," are specialized tissues in the body responsible for storing energy in the form of fat. While commonly associated with excess weight, adipose tissue is a vital and active endocrine organ that plays a crucial role in metabolism, insulation, and cushioning of organs.

There are two main types of adipose tissue: white adipose tissue (WAT) and brown adipose tissue (BAT). White adipose tissue is the predominant type, primarily functioning as an energy reserve. It stores lipids and releases them as fatty acids when the body requires energy. WAT also secretes hormones like leptin, which regulates appetite, and adiponectin, which influences insulin sensitivity.

Brown adipose tissue, found in smaller amounts, is specialized for thermogenesis, the process of generating heat. It is particularly abundant in infants and hibernating animals. When activated, BAT metabolizes fatty acids and glucose to produce heat, helping to maintain body temperature.

The distribution and amount of adipose tissue can vary significantly between individuals and are influenced by genetics, diet, physical activity, and hormonal factors. While a healthy amount of adipose tissue is essential for survival and normal bodily functions, excessive accumulation, particularly visceral fat surrounding internal organs, is linked to an increased risk of metabolic diseases such as type 2 diabetes, cardiovascular disease, and obesity. Conversely, insufficient adipose tissue can lead to difficulties in maintaining body temperature and energy deficits.
