Best Answer

The subunits of proteins are called amino acids. Amino acid molecules are smaller than protein molecules and are inside of the protein molecules.

Amino acids are joined together by peptide bonds where the -COOH group and the -NH2 group of two consecutive amino acids bond with the loss of a water molecule. The sequence of the amino acids make up the primary structure of the protein.

There are proteins composed of one long polypeptide chain (which means lots of amino acids linked). There are also proteins, like hemoglobin, which are made up of two or more polypeptide chains, joined together.

For example, "tetramer" refers to a protein with four subunits, or four different polypeptide chains.

Which protein powder is good for lean cut muscles?

Protein powders are concentrated sources of protein which supplement the calories which come from proteins. They are derived from various sources like plant and animal derived protein sources. Plant and animal derived protein sources include Whey Protein, Casein Protein and Soy Protein. Let us have a brief info about each of these protein derived from different sources.These are as follows-Whey Protein: It is milk derived protein and is considered the complete protein as it has essential amino acids. It is easily absorbed in blood and helps in protein synthesis.Casein Protein: It is also a milk derived protein and offers a good protein balance when taken in conjunction with whey protein. Casein protein is not absorbed that easily in blood.Soy Protein: It is a soy bean derived protein and acts as an excellent source of protein.
