PROTEINS

Proteins in the human body

Proteins perform most of the work inside cells. They build body structures and control many important processes.

Proteins have many important functions:

1. Structural function
Proteins build muscles, skin, hair, and organs.

2. Enzyme function
Proteins help chemical reactions happen faster inside the body.

3. Transport function
Proteins carry oxygen and nutrients through the body.

4. Protective function
Proteins help fight infections and form antibodies.

5. Regulatory function
Some proteins act as hormones and control body processes.

Every cell in the body contains proteins. Without proteins, cells cannot work, grow, or repair themselves.

Proteins are constantly being broken down and rebuilt. That is why the body needs a regular supply of amino acids from food.

Proteins are one of the most important substances that keep the human body alive and functioning properly.
