directions: there is a place on the coloring page to label each group of organic compounds. fill in the four blanks, giving the correct name of the organic compounds shown in each area.

Explanation:

1. Proteins are composed of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).
2. Amino - acids are the monomers of proteins.
3. There are 20 different amino - acids.
4. Amino acids have a carboxyl group, an amino group, and an R - group. Phosphate group is not part of a standard amino - acid structure.
5. The R - group is what differs among different amino - acids.
6. The shape of a protein determines its function.
7. A peptide bond is formed between two amino - acids.
8. A long chain of amino - acids is called a polypeptide.
9. Glycogen is a carbohydrate, not a protein. Antibodies, hormones, and enzymes can be proteins.
10. Nucleic acids store and transfer vital information to cells.
11. Nucleotides are the monomers of nucleic acids.
12. Amino acid is not a nucleic acid. DNA and RNA are nucleic acids, and ATP is a nucleotide derivative but not a nucleic acid in the traditional sense like DNA and RNA.
