Adipocytes, or lipocytes or fat cells, primarily compose adipose tissue and store fat as energy.<ref>Birbrair A, Zhang T, Wang ZM, Messi ML, Enikolopov GN, Mintz A, Delbono O (August 2013).

There are two types of adipose tissue, white adipose tissue (WAT) and brown adipose tissue (BAT), which are also known as white and brown fat, respectively, and comprise two types of fat cells.<ref>Available from https://en.wikipedia.org/wiki/Adipocyte#cite_note-Birbrair_2298%E2%80%932314-1</ref>

The WAT carries out functions of storage of fat, whereas BAT is involved in thermogenesis.

The brown color in the brown fat cells comes from the large quantity of mitochondria. Therefore, the brown fat, also known as "baby fat," is used to generate heat.11
