WebJun 9, 2015 · Firstly a note about terminology. The word "terminus" is reserved for the N- or C-termini of a polypeptide chain.For a free amino acid, you should refer to the carboxyl and amino groups as the $\alpha$-$\ce{COOH}$ and $\alpha$-$\ce{NH2}$ groups respectively.. Anyway, the - $\ce{COOH}$ group is acidic; above a certain pH, typically around 2, it can … WebThe values in the table below are normalized so that the most hydrophobic residue is given a value of 100 relative to glycine, which is considered neutral (0 value). The scales were extrapolated to residues which are more hydrophilic than glycine. A pH 2 values: Normalized from Sereda et al., J. Chrom. 676: 139-153 (1994).
