Understanding What a Protein Is
A protein is a large molecule made of amino acids. Proteins are essential for life because they help build tissues, repair cells, and support countless body functions.
What Proteins Do
Proteins strengthen muscles, transport nutrients, fight infections, and act as enzymes that speed up chemical reactions. Almost every process in the body uses proteins.
Where Proteins Come From
Proteins are found in foods like meat, eggs, fish, beans, nuts, and dairy. The body breaks them into amino acids and uses them to build new proteins as needed.
Types of Proteins in the Body
Different proteins have different roles. Structural proteins like collagen provide strength, while functional proteins like enzymes and antibodies control important processes.
Why Proteins Matter
Without enough protein, the body struggles to grow, heal, or maintain healthy tissues. Proteins are especially important for muscles, organs, skin, and the immune system.
The Simple Takeaway
Proteins are essential molecules made from amino acids. They build and repair the body, support vital functions, and keep you strong and healthy.
