Instructions: This only works for amino sequences. Enter an amino sequence. Valid symbols are:
G, A, V, L, I, S, T, N, Q, F, Y, W, C, M, P, D, E, K, R, H, *, X. You may copy and paste it from
a file. Then click on SUBMIT. The result page will show its equivalent charge and chemgroup string.

Note: If you include symbols other than those listed above, this script will remove them and attempt
to compute the charge and chemgroup string from whatever is left of the string or sequence.
