What does protein does for us

Proteins are essential macromolecules that perform a vast array of functions within our bodies. They are the building blocks for many structures, including muscles, bones, skin, and hair. Proteins also act as enzymes, which are crucial for catalyzing biochemical reactions necessary for metabolism and digestion. Furthermore, they function as antibodies to protect us from illness and as hormones to regulate bodily processes. Proteins are also involved in transporting molecules, such as hemoglobin carrying oxygen in the blood.
