Leptin, a palatability molecule ? – A Review

Palatability and feeding behaviour in ruminants. A review

Serum leptin is associated with the perception of palatability during a standardized high-carbohydrate breakfast test.

Leptin is an adipocyte-derived signalling molecule which plays a key role in the regulation of body weight and energy expenditure. Since its involvement in human eating behaviour is still poorly understood, we investigated whether the perception of palatability of food was related to fasting serum leptin levels. Twenty-six non-diabetic subjects, six men and twenty women of widely ranging age an...

Constructing a Body-Fixed Reference Frame for a Polyatomic Molecule

An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.

The biology of leptin: a review.

Leptin, a 16-kDa protein secreted from white adipocytes, has been implicated in the regulation of food intake, energy expenditure, and whole-body energy balance in rodents and humans. The gene encoding leptin was identified by positional cloning and is the mutation leading to the profound obese phenotype of the ob/ob mouse. Exogenous administration of leptin to ob/ob mice leads to a significant...

Pituitary Leptin-A Paracrine Regulator of Gonadotropes: A Review

Leptin, a potent anorexigenic hormone secreted primarily by adipocytes, is known to be expressed in the anterior pituitary. Studies in our laboratory found leptin proteins and mRNA predominantly in somatotropes in normal male and cycling female rats. In contrast, leptin expression predominated in gonadotropes during pregnancy and lactation. Leptin expression varied with the cycle and was enhanc...
