The genome of human beings and various animals contains an obese gene that codes for hormone called "leptin." This hormone, as it circulates in the body, consists of 146 amino acids and has a molecular weight of 16 kilodaltons, according to the Kenyon College Department of Biology. A proton weighs one dalton, so a leptin molecule weighs as much as 16,000 protons. Leptin theoretically plays a role in several physiological functions, especially body fat regulation.
