A starship expedition reported that it may have found evidence for the existence of life on Mars in the form of traces of molecules that appear to resemble an alien amino acid. While the scientific soundness of these claims remains fiercely debated amongst researchers the initial analysis of the alien amino acid suggested that it carried three different ionisable groups. This included an alpha amino group with a pka of 9.6 but surprisingly no alpha carboxyl group. In addition, the amino acid contained both the side chains found in histidine and the one found in aspartate.Use the pka table to determine the isoelectric point of the alien amino acid and provide the answer to two decimal places.
i) provide 3 to 4 bullet points text using to outline instructions that you did follow to determine the pI of the alien amino
ii) Use the pka table to determine the isoelectric point of the alien amino acid to two decimal places, show your working out and state the final result in a full sentence.
