Describe the following protein molecule's structure by its major components. A molecule is shown with components, from left to right, H2N, CHR minus O equals C minus NH minus CHR minus O euqals C minus NH minus CHR minus COOH. In this description, negative CHR means a that the four single bonds of the carbon atom are bonded to a hydrogen and a side chain R and a single bond to the left and right connecting to other components listed. Negative O equals C minus NH means the carbon is double bonded to an oxygen and single bonded to a component to the left and to the nitrogen to the right, while the nitrogen is single bonded to the carbon, hydrogen, and another component to the right. 3 amino acids joined by 3 peptide bonds
3 amino acids joined by 2 peptide bonds
2 amino acids joined by 3 peptide bonds
2 amino acids joined by 2 peptide bonds
