Adipose tissue

Definition

Adipose tissue is a type of connective tissue primarily composed of fat cells, or adipocytes. It stores energy in the form of lipids and provides insulation and cushioning for the body.

5 Must Know Facts For Your Next Test

1. Adipose tissue plays a crucial role in lipid metabolism by storing and releasing fatty acids as needed.
2. It consists mainly of triglycerides, which are broken down into glycerol and fatty acids during lipolysis.
3. Adipocytes secrete various signaling molecules known as adipokines that influence inflammation and metabolism.
4. There are two types of adipose tissue: white adipose tissue (WAT) and brown adipose tissue (BAT), each with distinct functions.
5. In microbial biochemistry, certain microbes can interact with or degrade components of adipose tissue, impacting host metabolism.
