Isoelectric Point of Amino Acids with MCAT shortcut

Amino Acid Isoelectric Point Calculation Tutorial Video

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 […]

Amino Acid Charge in Zwitterions and Isoelectric Point MCAT Tutorial

glycine protonated and deprotonated

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 […]
