Summary Introduction
To review:
The features of the DNA (deoxyribonucleic acid) molecule thatallow it to form the distinctive Z-DNA structure, containingzig-zag conformation of phosphate groups.
Introduction:
The first double-helical structure of DNA, discovered by Watson and Cric, ks known as B-DNA. DNA can form different conformations because deoxyribose sugar is flexible and the C’-N-glycosidic linkage can rotate. Z-DNA (Helix diameter of 1.84nm) is the Z form of DNA, which is slimmer than the B form of DNA.

Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvatedehydrogenase complex, resulting in acetyl-CoA and CO2. Provide a full mechanismfor this reaction utilizing the TPP cofactor. Include the roles of all cofactors.
B- Vitamins are converted readily into important metabolic cofactors. Deficiency inany one of them has serious side effects.
a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and ischaracterized by cardiac and neurological symptoms. One key diagnostic forthis disease is an increased level of pyruvate and α-ketoglutarate in thebloodstream. How does this vitamin deficiency lead to increased serumlevels of these factors?
b. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 5 deficiency?
c. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 2 /B 3 deficiency?
