- An organic chemist ordered the wrong item. She wanted to obtain 1-hydroxy-2-butanone, butinstead ordered 2-hydroxybutyraldehyde. As a good biochemist, show how the organic chemistcould use biological catalysis to make her desired compound.arrow_forwardPredict the products of aldolase catalyzing the reaction with acetone and (S)-3-hydroxybutyraldehyde.arrow_forwardA cancer patient undergoing chemotherapy is taking a protein kinase inhibitor drug.
