Human DNA contains about 30% each of adenine and thymine and about 20% each of guanine and cytosine. The bacteria Clostridium perfringes contains about 37% adenine and thymine and 13% guanine and cytosine. Explain how this information relates to the structure of DNA in general.
Stearolic acid (C18H32O2) yields stearic acid on catalytic hydrogenation and odergoes oxidative cleavage with ozone to yield nonanoic and monanedioic acid. What is the structure of stearolic acid? Account for the reactions indicated above. Would this acid have a higher or lower melting point than stearic acid. Explain.
Compound A is a D aldopentose that can be oxidized to optically inactive aldaric acid, B. On Kiliani-Fischer chain extension, A is converted into C and D. C can be oxidized to an optically active aldaric acid E, but D is oxidized to an optically inactive aldaric acid F. What are the structures of A-F?
