1. Building and Repairing Tissues: Proteins are the building blocks of our bodies. They are essential for constructing and maintaining tissues like muscles, bones, skin, and hair. Think of them as the "bricks and mortar" that hold our bodies together.
2. Enzymes and Hormones: Many proteins act as enzymes, which are biological catalysts that speed up chemical reactions in our bodies. They also make up essential hormones like insulin and growth hormone, which regulate a wide range of bodily functions.
3. Immune System Function: Proteins play a vital role in our immune system. Antibodies, which are proteins, help fight off infections and diseases. Proteins also form the basis of white blood cells, which are key components of our immune defense.
