Knowing how to find both charge and isoelectric point for amino acids is a critical MCAT skill. Understanding why an amino acid will gain or lose a proton at a given pH is even more critical. The MCAT is a test of logic and understanding, which is why this article will break down amino acid […]
Isoelectric Point of Amino Acids with MCAT shortcut
Isoelectric point calculations are critical in your biochemistry course and MCAT prep. The isoelectric point or pI gives you the pH at which the molecule has a net zero charge. This comes from a balance of protonation and deprotonation so that all positive and negative charges cancel out. This video shows you how to calculate […]
