What is the difference between cysteine and cystine?
Cysteine is the indivdual amino acid, cystine is the 2 bonded in a disulfide bond
Name the polar, acidic (-) amino acids
Aspartate/aspartic acid
Glutamate/glutamic acid
Name the polar, basic (+) amino acids
Lysine

What is the difference between aspartate and aspartic acid (same as glutamate/glutamic acid)?
Aspartate has the acidic R group as deprotonated (- charge), whereas aspartic acid still has the H+ on the R group, making it neutral
Are the acidic AAs polar or non polar?
Polar
Are the basic AAs polar or non polar?
Polar
