Welche Aufgaben haben Fette?

Fats perform a variety of important tasks and functions in the body:

1. **Energy supplier**: Fats are a concentrated energy source. They deliver about 9 calories per gram, which is more than twice as much as carbohydrates and proteins (both 4 calories per gram). The body stores excess energy in the form of fat in fat cells (adipocytes), which serve as energy reserves.

Two. **Constructions for cell membranes**: Fats, especially phospholipids, are essential components of cell membranes. They ensure the flexibility and integrity of the membranes and enable the transport of substances in and out of the cells.

3. **Isolation and protection**: Fat tissue serves as an insulation layer that protects the body from cold, and as a padding that protects sensitive organs from mechanical damage.

4. **Transport and intake of vitamins**: Certain vitamins (A, D, E and K) are fat-soluble and can only be absorbed and transported in the presence of fat. Fats are therefore necessary for the proper use of these vitamins in the body.

Five. **Hormon production and regulation**: Fats are precursor molecules for the synthesis of hormones, especially steroid hormones such as estrogen, testosterone and cortisol. These hormones are crucial for many physiological processes.

6. **Surface wearers and feeling of saturation**: Fats are flavor carriers that improve the taste and texture of food. They also contribute to saturation, as they slow down the gastric emptying and impart a longer-lasting saturation feeling.

7. **Essential fatty acids** The body needs certain fatty acids (such as omega-3 and omega-6 fatty acids) which it cannot produce itself. These essential fatty acids are important for inflammatory regulation, brain function and other physiological processes.

In the body, fats are broken down into smaller components after they have been taken up in the digestive tract and absorbed into the bloodstream. They are then used either for immediate energy recovery, stored in the cells for later use or installed in lipoproteins to circulate through the blood and reach various tissues.
