Question

Protein composes 10-30% of cell mass and is the basic structural material of the body. However, not all proteins are construction materials. Many play vital roles in cell function. Proteins, which include enzymes (biological catalysts), hemoglobin of the blood, and contractile proteins of muscle, have the most varied function of any molecules in the body. All proteins contain carbon, oxygen, hydrogen, and nitrogen, and many contain sulfur as well. The building blocks of proteins are __________.

Answer 1

Answer:

Amino acids

Explanation:

Like a house, every molecule is formed of units (blocks) that determine their structure and function. Proteins have a diverse functions in the body and are very important in multiple biological processes.  Proteins are molecules called polymers (molecules formed by monomers), the simplest units of proteins are the amino acids (building blocks). The amino acids are bind together by peptide bonds and when the chain of amino acids is less than 30 is called peptide and more than 30 is called protein. Every amino acid has a special structure and the type and number of aminoacids determinate the structure and function of the protein.
