Cysteine s-conjugate n-acetyltransferase

You will measure, dilute and measure until you get an absorbance between 1 and 2 (in the Beer's law range). As Jack wrote, you need a molar extinction coefficient. Your path length is likely 1cm for a garden-variety spectrometer. Solve Beer's law for the concentration, then plug in your values for t...

... Glycine is of course an exception. Proline as well, since it is an imino acid. Alanine is the "basic" amino acid. Now, serine and cysteine are hydroxy- and thiol derivatives. Valine and leucine are dimethyl and isopropyl derivatives. Isoleucine is not iso- for no reason, so you ...
