With the changing environments the reactions of metabolism must be finely regulated to maintain a constant set of conditions within cells, a condition called homeostasis. Control of metabolic pathways also allows organisms to respond to signals and interact actively with their environments.

Metabolism Energy Transformations

The energy for various functions of the human body comes from the nutrient molecules that have been metabolised. In fact, the main purpose of food intake is supply of energy. This energy comes from the fats, carbohydrates, and proteins in food. Of the three, fat is the most concentrated source of energy because it furnishes more than twice as much energy for a given weight as protein or carbohydrate.

Lipogenesis Control and Regulation

Lipogenesis is the process involving the synthesis of fatty acids or triglycerides, which is controlled and regulated by a number of factors in the body. The process is stimulated by a diet high in carbohydrates and several hormones in the body, such as insulin, mediate the process.

What is Lipogenesis?

Lipogenesis is a term used to describe a process of fatty acid and triglyceride synthesis from glucose or other substrates. This specific biosynthesis takes place predominantly in the liver, while its occurrence in the adipose tissue is of minor significance – even under conditions of substantial carbohydrate overfeeding.
