2. How many different proteins are found in humans: 20,000 3. What are the 5 functions of proteins:
transport hormones
catalysis structure
protection
4. What is protein transport: proteins help move molecules around the cell and organism
5. What is an example of a transport protein: hemoglobin
6. What is hemoglobin's function: blood-based protein that carries oxygen from long to tissues
7. What is protein hormones: molecules that communicate messages between
cells
8. What is an example of protein hormones: relaxin
9. What is the function of relaxin: protein hormone that helps women relax pelvic ligaments during childbirth
10. What are protein catalysis: enzymes that speed up chemical reactions
11. What is an example of a catalysis protein: protease
12. What is protease's function: breaks down proetins in cells to help organism recycle unneeded proteins
13. What is a household use for protease: added to laundry detergent to degrade blood or food stains in clothes
14. What are structure proteins: proteins that give strength to cells, organelles, and tissues

, 18. What is an example of protection proteins: antibodies 19. What is an amino acid made of: amine carboxylic
acid
Hydrogen R
group
all connected to central carbon
20. What is the R group of an amino acid called: side chain of the amino acid
21. What are the nonpolar aliphatic amino acids: Glycine Alanine
Valine
Proline
Leucine
Isoleucine
Methionine
22. What are aliphatic amin acids: often found in the interior of the protein, away from water, nestled with other
aliphatic groups
23. Why is proline unique?: r group folds back and bonds with backbone making it not flexible
24. What are non-polar aromatic groups: phenylamine
Tryptophan Tyrosine
25. What makes non-polar aromatic amin acids unique: side chains of these compounds contain a ring of carbons as
an aromatic functional group
26. What are the polar neutral amino acids: Serine
Threonine
