1. Macromolecules

3. Proteins C, H, O, N (and other elements)
basic building materials of all living things
ex: muscle, hair, nails, web, horns, hormones, enzymes, antibodies, hemoglobin

4. Examples of Structural Proteins

5. Examples of Functional Proteins
Antibodies
Hormones
Enzymes
Hemoglobin

6. Proteins made of monomers called amino acids.

7. There are 20 different amino acids.

8. Amino acids bond together by having the amino group of 1 bond with the acid group of another - peptide bond. They form a dipeptide.

9. Proteins are made of 1 or more polypeptide chains
Proteins are made of 1 or more polypeptide chains. Some are in long chains, some wrap around each other, or are “woven” in layers.

10. Enzymes
Some proteins act as a catalysts - speed up reactions without becoming involved in them. These are called enzymes.

11. Enzymes enable reactions to occur without excessive heat (body temperature)

12. Nucleic Acids store and transmit hereditary information
made of monomers called nucleotides
contains a sugar, a base, and a phosphate group PO4

13. 2 Kinds of Nucleic Acids DNA - deoxyribonucleic acid
records the genetic instructions and transmits them from generation to generation
the “master” molecule

14. 2. RNA - ribonucleic acid
“reads” the DNA instructions and carries them out
the “slaves” for DNA

15. ATP = energy
Cells use ATP for energy.
