Lysine net charge

Web22 feb. 2006 · Lysine's side-chain (amino group at the end of its side chain) has a pKa of about 9-10, so at pH = 14, it will be DEPROTONATED (0 charge) Therefore, the net charge on Lysine at pH=14 is -1 + 0 + 0 = -1. By similar reasoning, at physiological pH, the net charge on Lysine is: -1 + 1 + 1 = +1. WebCalculate the net charge of lysine at pH 1. Question options: a)0 b)-1 c)-2 d)+1 e)+2 2.

These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base. Their pKa's are high enough that they tend to bind protons, gaining a positive charge in the process. psc internships
