When the pH of the solution is significantly different from the pKa of a drug we can calculate the oglesbee obituaryWebNational Center for Biotechnology Information ogle motors woodbridge

"In computational biology, protein pKa calculations are used to estimate the pKa values of amino acids as they exist within proteins. These calculations complement the pKa values reported for amino acids in their free state, and are used frequently within the fields of molecular modeling, structural bioinformatics, and computational biology.
