Lipid synthesis and breakdown - crucial mechanisms related to fat tissue

The basic group of energy substances is carbohydrates, present in virtually every food product consumed (fruits, vegetables, etc.). Their distribution provides energy, which is accumulated in the chemical bonds of m. It comes from food, and is released from the high-energy chemicals of its constituent molecules. The primary group of energetic substances are carbs, which are present in practically every meal product eaten (fruit, vegetable, etc..). Their distribution supplies energy, and the energy accumulation in these molecules is from food. In particular, ATP (adenosine triphosphate) acts as a carrier energy source for the body.

There are two mechanisms associated with the accumulation or release of free fatty acids by adipocytes (fatty cells), namely lipolysis and lipogenesis. A mechanism related to the capture (accumulation) of fat is called lipogenization. If the energy balance in the human body is positive, then free fat acids are accumulated in the form of triglycerides, which accumulate in the liver and fat tissue.

The mechanism of lipolysis is the opposite of lipogenesis. It occurs during increased energy demand, i.e. during increased physical exertion, or at the time of lowering the ambient temperature. Lipolysis can also occur during stressful situations such as hunger.

The mechanisms described above (lipolysis and lipogenesis) control an enzyme called lipoprotein lipase, which improves the transport of free fatty acids to the inside of cells. It makes it possible to synthesize the HDL fraction of (good) cholesterol from the fatty acid. Insulin and glycocorticosteroids, as well as an increase in the number of adipocytes in the body, increase the activity of lipoproteins. However, its activity is reduced by growth hormones, testosterone and estrogen.
