Scientific Background:Leptin, the product of the ob (obese) gene, is a 16kDa protein consisting of 146 amino acid residues. Leptin is produced in the adipose tissue, and is considered to play an important role in appetite control, fat metabolism and regulation of body weight. Studies have shown that it may also influence reproductive function. Mice with ob/ob genotype develop a form of diabetes similar to type II in humans.
