Hi,
*guess i may have posted on the wrong forum... sorrie folks!!
I've encounter some problems in assigning charges to the amino acids..any advice on how to to go about it?
Am i right to say:
For basic amino acids: pH>pKa, net charge is -1; pH<pKa, net charge is +1; pH=pKa, net charge is -0.5
For acidic amino acids: pH>pKa, net charge is +1; pH<pKa, net charge is -1; pH=pKa, net charge is +0.5
1) So when does an amino acid has a charge of 0? (when pH=pI??)
2) What categories do Cys, Gly and Pro belongs to?
Thanks for any guidance on the topic. ^0^
