What defines a protein?

Medical Definition of Proteins Proteins: Large molecules composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein. Proteins are required for the structure, function, and regulation of the body’s cells, tissues, and organs.Click to see full answer. Subsequently, one may also ask, what makes something a protein?Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. These proteins bind and carry atoms and small molecules within cells and throughout the body.Subsequently, question is, what is the function of proteins in biology? In Summary: Function of Proteins Proteins are a class of macromolecules that perform a diverse range of functions for the cell. They help in metabolism by providing structural support and by acting as enzymes, carriers, or hormones. The building blocks of proteins (monomers) are amino acids. Considering this, what is a simple definition of protein? The definition of a protein is a substance that has amino acids, compounds and carbon, hydrogen, oxygen, nitrogen and sometimes sulfur and is found in many foods. An example of a protein is the type of nutrient found in meats.What elements make up proteins??Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen and Nitrogen. Proteins are crated by linking together amino acids into protein links called polypeptide chains.
