Here's why:
* Made up of amino acids: Proteins are indeed composed of long chains of amino acids linked together.
* Needed to build and repair body structures: Proteins are essential for building and repairing tissues, muscles, bones, skin, and hair.
* Regulate processes in the body: Proteins play a crucial role in regulating various bodily processes such as:
* Enzymes: Many enzymes, which catalyze chemical reactions in the body, are proteins.
* Hormones: Some hormones, like insulin and growth hormone, are proteins.
* Antibodies: Proteins form the basis of our immune system, helping fight off infections.
* Transport: Proteins help transport substances like oxygen and nutrients throughout the body.
While proteins do provide some energy, their primary function is not energy production. They are more important for building and maintaining the body's structure and functions.
