zsírrétege

Zsírréteg, commonly translated as fat layer or adipose tissue, refers to the subcutaneous layer of fat found beneath the skin in animals. This layer serves several crucial functions. Primarily, it acts as an insulator, helping to regulate body temperature by trapping heat and preventing its loss to the environment. This is particularly important for animals living in cold climates.

Beyond insulation, zsírréteg functions as an energy reserve. When food is scarce, the body can break down stored fat for fuel, providing essential energy for metabolic processes and survival. The thickness of this layer can vary significantly depending on the species, an individual animal's health, nutritional status, and environmental conditions. For example, marine mammals like whales and seals have exceptionally thick zsírrétege to survive in frigid waters.

Zsírréteg also plays a role in protecting internal organs from physical shock and injury. The cushioning effect of the fat layer helps to absorb impacts, safeguarding delicate organs from damage. Furthermore, it contributes to the overall shape and contour of an animal's body. In some species, the distribution of zsírréteg can be sexually dimorphic, meaning it differs between males and females, potentially playing a role in mate attraction or other social behaviors. The composition of zsírréteg is primarily triglycerides, which are a type of lipid.
