Unit 1: Biochem - proteins Flashcards
1
Q
functions
A
- enzymes
- structure
- transport
- cell communication
- defence
- movement
2
Q
elements (4)
A
C. N, H, O
3
Q
monomer
A
amino acids
4
Q
how many different amino acids make up proteins
A
20
5
Q
components of an amino acid
A
- amino
- r group (determines unique traits of the amino acid)
- carboxylic acid
6
Q
polymers of proteins
A
polypeptide
7
Q
polypeptide
A
- structure = function
- held together by peptide bonds
8
Q
primary structure of proteins
A
determined by the order of the amino acids
9
Q
secondary structure of proteins
A
local hydrogen bonding between r groups
- makes the strand either an alpha helix or beta pleated sheet
10
Q
tertiary structure of proteins
A
hydrogen bonding between farther r groups (twisting and turning)
- hydrophobic –> turn towards middle of cell
- hydrophilic –> turn towards outside of cell
11
Q
quaternary structure
A
puts multiple proteins together to become a functional protein
