What is a protein?
Proteins are biomolecules that contain many amide bonds, formed by joining amino acids
Proteins are large, complex molecules that are essential for the proper functioning of organisms. They are made up of long chains of amino acids that are held together by peptide bonds. There are 20 different types of amino acids that can be combined in various ways to form different types of proteins.
Proteins have a wide range of functions in the body including:
1. Enzymatic catalysis: Proteins act as catalysts to speed up chemical reactions in the body.
2. Structural support: Proteins form the structural backbone of cells, tissues, and organs.
3. Transport: Proteins help to transport molecules and ions across cell membranes.
4. Signaling: Proteins act as messengers to transmit signals between cells.
5. Defense: Proteins are a key component of the immune system and help to defend against infection and disease.
Proteins can be found in a wide range of foods, including meat, dairy, eggs, beans, nuts, and seeds. They are broken down into amino acids during digestion, which are then used by the body to build new proteins.
