23
Q

What is the difference between cysteine and cystine?

24
Q

Name the polar, acidic (-) amino acids

A

Aspartate/aspartic acid

Q

Name the aromatic AAs

A

Phenylalanine
Tyrosine
Tryptophan

27
Q

What is the difference between aspartate and aspartic acid (same as glutamate/glutamic acid)?

A

Aspartate has the acidic R group as deprotonated (- charge), whereas aspartic acid still has the H+ on the R group, making it neutral

28
Q

Are the acidic AAs polar or non polar?

A

Polar

29
Q

Are the basic AAs polar or non polar?

A

Polar
