A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.
Moreover, how do proteins work?
Proteins are responsible for catalyzing chemical reactions like digesting food, transporting substances across organs, pathogen clearing, recognizing signaling molecules, and much more within your body. In the human body alone, there are more than 100,000 different proteins at work, all serving critical functions.

|---|---|
| Type | Examples |
| Transport | Hemoglobin, albumin |
| Structural | Actin, tubulin, keratin |
| Hormones | Insulin, thyroxine |

What is protein and examples?
Proteins are organic molecules that are present in living organisms. They serve a wide range of functions including organization, transportation, and defense. Proteins are composed of amino acid chains, and structure levels are up to four. Certain specific protein examples include collagen, insulin, and anticorps.
What is protein and why is it important?
Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.
What is protein in your body?
Protein is one of a complex group of molecules that do all kinds of jobs in your body. They make up your hair, nails, bones, and muscles. Protein gives tissues and organs their shape and also helps them work the way they should. In short, protein is one of the building blocks that make you into who you are.
What is protein made of?
What Are Proteins Made Of? The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).
What is the definition of protein in food?
