1. General Biology - Biochemistry
Proteins

2. Proteins
• Building Blocks of living things
• Contain C, H, O
• and Nitrogen (N)
• Built from monomers called
• AMINO ACIDS

3. All amino acids have:
• 1. A Carboxyl group
• 2. An amino group
• 3. “R” group This is a carbon chain that
distinguishes one amino acid from another

6. How to build a protein…

7. What would we call two amino acids together?
What would we call many amino acids together?

9. Two types of Proteins
STRUCTURAL FUNCTIONAL
PROTEINS PROTEINS
Muscles Enzymes
Collagen Hormones
Keratin Antibodies
Membranes Hemoglobin

10. Food Sources of Protein

11. Structural
Protein:
Collagen

12. keratin

13. fiberon

15. Functional
proteins:
enzymes

16. how many different in
proteins in the world?
• How many letters in the alphabet?
• How many words can you build?
• How many amino acids?
• How many proteins?
• Smallest proteins = about 500 amino
acids

17. Soooooo……
• What are the building blocks of living
things?
• What are the building blocks of
proteins?
• What are the two types of proteins?

18. On to Nucleic Acids

19. Nucleic Acids
• Huge macromolecules
• Information transfer
• Contain C, H, O, N, Phosphorous
• Made of monomers called
nucleotides
• Examples include
• DNA (deoxyribonucleic acid)
• RNA (ribonucleic acid)

21. We will cover in depth in
Genetics Unit not now

22. Bases
Phosphate
group
5 carbon
Deoxyribose sugar

23. Organic molecules
• Carbohydrates – energy –structure – glucose-mon,di, poly
• Lipids – energy –structure-fatty acids/glycerol – triglyc,
phosp
• Proteins-structure – function – amino acids- polypeptides
• Nucleic Acids – information-nucleic acids- DNA, RNA
