Proteïene

Proteïene are large, complex molecules that play many crucial roles in the body. They are made up of smaller units called amino acids, which are linked together in long chains. The specific sequence of amino acids determines the protein's unique structure and function.

Proteins are essential for a wide range of bodily functions. They serve as building blocks for tissues such as muscles, bones, and skin. Proteins also act as enzymes, catalyzing biochemical reactions that are vital for metabolism and energy production. Furthermore, they function as antibodies, defending the body against infections and diseases. Other important roles include transporting molecules throughout the body, such as oxygen carried by hemoglobin, and regulating cellular processes.

The human body can synthesize some amino acids internally, but others, known as essential amino acids, must be obtained from the diet. Foods rich in protein include meat, fish, dairy products, eggs, legumes, and nuts. The recommended daily intake of protein varies depending on age, activity level, and overall health.
