D (dextro - right) and L (levo - left). 10. Briefly describe the results of the fermentation demonstration. Only the D form of the sugar was acted upon by the yeast to bring about fermentation. 11. What happens to the optical activity of an amino acids in protein as it decomposes? One form (D or L) is converted to the other (Racemization). 12. How is the process described in Question 11 used to determine the age of objects? The less the optical activity the older the object....
