Proteins?Polymers of Amino Acids. Proteins, found in all cells, are the most complex and variable of all molecules. The main elements in proteins are C, H, O, and N, but many others contain S, and some have P, Fe, Zn, or Cu. The molar mass ranges from 12,000 to over 1 million. Amino Acids. Protein

    2. Proteins—Polymers of Amino Acids Proteins, found in all cells, are the most complex and variable of all molecules. The main elements in proteins are C, H, O, and N, but many others contain S, and some have P, Fe, Zn, or Cu. The molar mass ranges from 12,000 to over 1 million

    3. Amino Acids Proteins are polymers of amino acids, molecules with both an amino group (-NH2), and a carboxyllic acid group (-C-OH). These are linked in long chains by O an amide linkage called a peptide bond. The amino acids all belong to the L- optical isomer group, none used in proteins are D-. There are 20 which are found in proteins, but only 10 can be made in humans, the others must be in our diet and are called essential. A protein which supplies all of these is called adequate; animal sources are all adequate, plant sources are not always.
