Brown Adipose Tissue

Also known as:  BAT;  Brown Fat

Brown Adipose Tissue is a type of Adipose Tissue composed of Adipocytes.  It contains a “richer” supply of Blood Vessels compared to White Adipose Tissue and contains a larger number of Mitochondria compared to White Adipose Tissue.  Brown Adipose Tissue is estimated to comprise approximately 10% of the body’s total Adipose Tissue.

Metabolism

 Brown Adipose Tissue contains Beta-3 Adrenergic Receptors - activation of these Beta-3 Adrenergic Receptors stimulates and within Adipose Tissue:

 The number of Beta-3 Adrenergic Receptors in the body’s Brown Adipose Tissue varies with each individual - persons with a genetic predisposition to Obesity or Diabetes Mellitus Type 2 have a diminished number of and/or defective Beta-3 Adrenergic Receptors.
