The structural formula of the amino acid leucine most prevalent at pH 10.0 has to be drawn. Concept Introduction: The isoelectric point ( pI ) of an amino acid is said to be the pH at which the molecules in the amino acid solution have net charge zero. At isoelectric point, the Zwitter ion form of amino acids is more prominent. When the pH of the amino acid is greater than the pI of the amino acid, it has a net negative charge. When pH of the amino acid is lesser than the pI of the amino acid, it has net positive charge.
