- Which of the following statements about proteins is correct? There are 20 types of amino acids commonly found in proteins. Proteins are composed of glyosidic bonds. Proteins are never folded. They do not contain any hydrophilic or hydrophobic residues. Peptide bonds are composed of only carbon and oxygen atoms.arrow_forwardWhat causes a protein to fold? A. Chemical interactions between the specific R-groups of the protein chain B. Chemical interactions that draw certain nucleotides together C. Chemical attractions between amino groups and acid groups that form covalent bonds D.

Quaternary structure is unaffected by acids or heat. Quaternary structure is determined by the same interaction that holds an α-helix together. Quaternary structure is how prosthetic groups are held in a protein. Quaternary structure is the position of subunits in the overall structure of a protein. All proteins have quaternary structurearrow_forward
