1.2 Amino Acid Structure (R Groups) Flashcards
1
Q
Proteins are polymers, thus amino acids are
A
Monomers
2
Q
Amino acids are linked with..
A
Peptide bonds, to form polypeptides
3
Q
Amino acids are classified according to their R groups- these are…
A
Basic
Acidic
Polar
Hydrophobic
4
Q
What charge do basic amino acid R groups have
A
Positive
5
Q
What charge do acidic amino acid R groups have
A
Negative
6
Q
Functions carried out by proteins are a result of
A
The diversity of amino acid R groups
7
Q
Describe the structure of a basic R group
A
These contain an amino acid side chain
(NH2)
8
Q
Describe the structure of an acidic R group
A
These contain a carboxylic acid side chain
(COOH)
9
Q
Describe polar R groups
A
They are hydrophilic so seek contact with aqueous solutions
Eg serine
10
Q
Describe hydrophobic R groups
A
These avoid contact with water
