What z Net charge of a dipeptide Glu-Lys at physiological pH?
The net charge is 0. First, lets look at the two amino acids separately. For Lys, you have: pka1=2.2 (coo-) pka2=9.1(NH2+) pka3=10.5 (lateral chain) For glu, you have: pka1=2.1(COO-) pka2=4.1 (lateral chain) pka3=9.5(NH2+) First, below 2.1: 100% of : NH2+---------CH----CO-NH---CH-----COOH (CHARGE=2+) COOH NH+ At 2.1: 50% of :NH2+---------CH----CO-NH---CH-----COOH COOH NH+ 50% of :NH2+---------CH----CO-NH---CH-----COOH (here, we see that there was no COOH NH+ change, WHY: the carboxyl of glu should be ionized at 2.1, but it is attached to the amino group of lys, so there is no change At 2.2 ...of NH2+---------CH----CO-NH---CH-----COO- (charge+1) COOH NH+ At 4.1 ....of NH2+---------CH----CO-NH---CH-----COO- (CHARGE=0) COO- NH+ At pI = 6.8 100 % of NH2+---------CH----CO-NH---CH-----COO- (CHARGE=0) COO- NH+ Since the next pka is at 9.1, we don't have any change yet at the physical pH 7.4. Thus, the charge is zero. I didn't put the pI in between b4, it would just take too much time, but I hope that you do understand the concept now. Good luck
