Answer: B. complex, folded chains of amino acid

Proteins are a class of large organic compounds composed of amino acids in the form of one or more long chains. The amino acid sequence determines the protein's shape and is in turn dictated by the DNA sequence that codes it. Proteins are vital for all the body's functions.
