33
Q

Negatively Charged R Groups (2)

A

34
Q

Traits of Nonpolar, aliphatic group (3)

A

hydrophobic
nonpolar
stabilize protein structure via hydrophobic effect

35
Q

Traits of aromatic r groups (3)

A
  • relatively Nonpolar (hydrophobic)
  • all contribute to the HP effect
    Polarity: Tyrosine = Tryptophan > Phenylalanine
36
Q

Traits of Polar Uncharged R Groups (2)

A
  • Soluble in H2O
  • more hydrophilic then Nonpolar, aliphatic group
