Polypeptide chainwith 21 basic and 15 acidic residues...

[qwertyqwerty]

So if a polypeptide chain of 214 amino acid residues has 21 basic and 15 acidic residues, the protein :

a) is amphipathic
b) will be positively charged at neutral pH
c) unlikely to be found inside cells because it is too highly charged
d) will have no net charge at pH 7
e) would be expected to form 15 ion fairs

I think its between b and c but I'm not sure which one. And does amphipathic only apply to polar/non polar, and not acidic/basic, right?

c is really funny no, seriously, it's simply b
