Summary

Leptin (16 kDa, 146 amino acid residues), the product of the ob gene, is produced in the adipose tissue and is considered to play an important role in appetite control, fat metabolism and body weight regulation. It targets the
hypothalamus, affecting food intake. It decreases the appetite and increases energy consumption. Leptin is secreted in circadian fashion with nocturnal rise in both lean and obese patients. Leptin may be linked to reproductive function.
