What is a simple definition of protein?
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.
What is a amino acids in medical terms?
Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.

What does core protein mean?
Medical Definition of core protein : any of various proteins that play a major structural or functional role in a large molecular complex of which they are part: as. a : an inner coat of protein that surrounds the genetic material of some viruses.
Why is it called protein?
Why are they called Proteins? Protein comes from the Greek word proteios, meaning “primary” or “holding the first place.” A Dutch chemist Gerard Johann Mulder, coined the word protein in 1838. Proteins are made from chains of amino acids. A protein often consists of hundreds of amino acids linked together.
What are the 3 types of protein?
The three structures of proteins are fibrous, globular and membrane, which can also be broken down by each protein’s function. Keep reading for examples of proteins in each category and in which foods you can find them.
What are amino acids good for?
Muscle function Proper amino acid levels are important for muscle development and strength. They help control the balance between the atrophy and growth of human muscle. Supplementing your diet with essential amino acids may increase the supply of nitrogen to your body.

What is the protein core of virus?
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
What is the function of proteoglycans in the body?
The major biological function of proteoglycans derives from the physicochemical characteristics of the glycosaminoglycan component of the molecule, which provides hydration and swelling pressure to the tissue enabling it to withstand compressional forces.
