Unit 1 Protiens

Question 1

What are the types of protiens?
1. amino acids
2. Polypeptides

Answer 1

1. amino acids:
   -monomer of Protiens
   -made of carboxyle group + animo group (N+H) + Rest
2. Polypeptides:
   -long amino chain
   -many amino acids
   -held together by peptide bonds

Question 2

How to tell if a amino acid is polar, non-polar, acids, or bases?

Answer 2

Polar:
-uneven charges in R group
-most likely has Oxygen

Non-polar:
-even charges is R group
-most likey doesn’t have Oxygen

Acids:
- has negative charge

Base:
-has positive charge

Question 3

peptide bonds

Answer 3

Amino acids + amino acids = Protien

Bond: peptide(dehydration snythesis)

bond happends between N-Terminal (amino group) and C-terminal (carboxyal end)

Question 4

Describe the structures of proteins
1. primary structure
2. secondary structure
3. tertiary structure:
4. Quaternary structure:

Answer 4

Structure = function
protiens are folded

1. primary structure:
   -amino acid + amino acid
   Bonds; peptide bonds
   shape: annal beads
2. secondary structure
   -a helix
   -b pleted sheet
   Bonds: hydrogen bonding
3. tertiary structure:
   -complex shape
   Bonds: Hydrogen bonding, disulfide bridge, hydrophobic, hydophilic, ionic bonding
   Shape: S
4. Quaternary structure:
   -polypeptide + polypeptide
   Bonds: Van der Waals force, aggrevation of 2+ polypeptides
   Shape: spaghetti

Question 5

Protein synthesis vs denaturation

Answer 5

protien synthesis:
fold proteins into structures
-chaperone protines and prosthetic group

denaturation:
unfolds protien
-heat, cold, salt, pH
