Q

Protein functions

A

22
Q

The only codon that produces methionine is

A

ATG

23
Q

The only codon for tryptophan is

A

TGG

24
Q

What are the parts of an amino acid?

A

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

25
Q

Why is cysteine a unique amino acid?

A

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

26
Q

What is glycine unique?

A

Glycine has 2 hydrogens; it is achiral*

*Chiral carbon = bonded to 4 different things

27
Q

What is unique about tryptophan?

A

It has the largest side chain

28
Q

Non polar amino acids

A

Hydrophobic
Gly, Ala, Val, Leu, lle, Pro, Phe, Trp, Met

mnemonic I play: GILVAP on MWF

29
Q

Which amino acid is an imino acid?

A

Pro

30
Q

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

A

Phe and Trp

31
Q

Polar uncharged amino acids

A

-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

Ser, Thr, Cys, Tyr, Asn, Gln

32
Q

Polar charged amino acids

A

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)

33
Q

Which amino acid can partially meet the need for methionine?

A

Cysteine

*both contain sulfur

34
Q

Which amino acid can partially substitute for phenylalanine?

A

Tyrosine
