On the other hand, and focusing on the target classes with large numbers of compounds, the ones with the largest percentages of molecules without scaffolds are "7TM1" (49%), "Oxidoreductase" (40%), and "Electrochemical transporter" (38%). We have seen before the large number of fatty acids and derivatives ("Fatty Acyls" and "Organic acids and derivatives") targeting the "7TM1" class, and this applies also the two other classes.
