Describe the structure of protein and it's functions.
Proteins are complex molecules that play essential roles in living organisms. They are made up of long chains of amino acids, which are organic compounds. The structure of a protein consists of four levels: primary, secondary, tertiary, and quaternary.
1. Primary structure: This refers to the specific sequence of amino acids in a protein chain. The order of amino acids is determined by the genetic code encoded in the DNA of an organism.
2. Secondary structure: Protein chains often fold into...
