7.1 Flashcards
1
Q
primary structure
A
amino acids on a peptide chain
2
Q
secondary structure
A
folded structures formed within polypeptide chains, alpha helix and beta pleated
3
Q
tertiary structure
A
overall 3-D structure of a polypeptide interactions between amino acids
4
Q
quarternary
A
more than 1 polypeptide chain
5
Q
enzymes
A
cut and join molecules
6
Q
hydrophilic
A
hydrophilic elements turn to the outside
7
Q
hydrophobic
A
turn to the inside
8
Q
acidic and basic
A
form ionic bonds with each other
9
Q
cysteine
A
form disulfide bonds
10
Q
Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one?
A
the structure would change because that area of the side chain would be pulled toward the outside of it
