Question 24

What are the parts of an amino acid?

Answer 24

Amino group (NH2), carboxyl group (COOH), a functional group (R), and a Hydrogen are all attached to a central alpha carbon

Question 25

Why is cysteine a unique amino acid?

Answer 25

It contains SH group, which allows cysteine to form disulfide bonds

Question 26

What is glycine unique?

Answer 26

Glycine has 2 hydrogens; it is achiral* *Chiral carbon = bonded to 4 different things

Question 27

What is unique about tryptophan?

Answer 27

It has the largest side chain

Question 28

Question 30

Which two non polar amino acids have heterocyclic rings in their side chains

Answer 30

Phe and Trp

Question 31

Polar uncharged amino acids

Answer 31

-Hydrophilic b/c of polar functional groups (o & n which can participate in hydrogen bonding with water) -glycine is not polar, but is included in this group b/c the H of its R group can be used to H-bond with other polar groups Skiers Canoeing Talking Yes No Questions Ser, Thr, Cys, Tyr, Asn, Gln

Question 32

Polar charged amino acids

Answer 32

DEk HaRd Asp, Glu, Lys, Arg, His Lys, Arg, and His are polar basic and carry a plus charge Asp, and Glu are negatively charged (polar acidic)
