How do you determine if a compound is identical or enantiomer and if they have an R or S configuration? CH_2Br_2 a) are they identical (superimposable) or different (non-superimposable)? b) are they isomers? Explain. Identify the relationship between t[{I...
Explain what an enantiomer is in detail with an example. Describe two different mixtures of starting materials that can be used to produce the equilibrium: A + B to C + D. Explain why the pure solvent shows a level horizontal curve as solidifi...
Notice that these are different molecules. We are not talking about rotating about an axis or a single bond, in which case the absolute configuration(s) must stay the same. We are actually converting to a different molecule by swapping the groups to make it easier to determine theRandSconfigu...
Likewise, it will be necessary to identify full-length AlbAL and the truncated AlbAS species in vivo, and to quantify their cellular abundances. Given the ligand promiscuity of the TipAS system27,36, and other MerR effector-binding domains (i.e., BmrR)37, we studied whether AlbAS can ...
Cancer metabolism has received a substantial amount of interest over the past decade. The advances in analytical tools have, along with the rapid progress of cancer genomics, generated an increasingly complex understanding of metabolic reprogramming in c

Identify the drug targets in the protistan parasites. A patient insists that he needs an antibiotic to treat his viral infection. Explain to him why an antibiotic will not help him get better. For penicillin, tetracycline, and erythromycin, what is the mechanism by which each antibi...
Identify the chirality center(s) in the compound. How many stereoisomers exist for this compound? How many possible isomers exist for diacetylferrocene? How many unique stereoisomers exist for 2,3-difluoropentane? Pay close attention to the name - this is not a cyclic structure! In addition,...
Describe an ionic crystal. What factors might determine the geometrical arrangement of the ions? How can spectroscopy be used to identify the presence of specific elements in a substance? How do you distinguish between fluorene and acetanilide? Suggest methods other than melting point and chrom...
An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomer. The mixture had an observed specific rotation of +13.5degree. If it is known that the specific r Identify these unknown organic...
