Refer to table that lists the pKa values of amino acids at physiological pH and select all that are correct Total of 7 amino acids will be charged at physiological $$\mathrm{pH}$$ due to their side chains Lysine and arginine will be positively charged at their side chain glutamate and aspartate will be negatively charged at their side chain. The carboxylic and amino group attached to the central carbon atom of histidine will be negatively and positively charged respectively and the charge will cancel out
