The steroid ring structure is complex and contains many chiral carbons (for example at positions 5, 8, 9,10,13,14 and 17) thus many optical isomers are possible. (The actual number of optical isomers is given by 2" where n = the number of chiral carbons). From your knowledge of biochemistry you should have realised that only one of these optical isomers is likely to be biologically active. Synthesis of such a complex chemical structure to produce a single isomeric form is extremely difficult, especially when it is realised that many chemical reactions lead to the formation of racemic mixtures. Thus, for complete chemical synthesis, we must anticipate that...

By all accounts, the hypothesis of formation of DNA+adamantane+amino acid nanoarchitectures is currently immature and amenable to many technical modifications. Advancement in this subject requires a challenging combination of state-of-the-art approaches of organic chemistry, biochemistry, proteomics, and surface science. 

In the classical world (and biochemistry textbooks), transition state theory has been used extensively to model enzyme catalysis. The basic premise of transition state theory is that the reaction converting reactants (e.g. A-H + B) to products (e.g. A + B-H) is treated as a two-step reaction over a static potential energy barrier (Figure 2.1). In Figure 2.1, [A - H B] is the transition state, which can interconvert reversibly with the reactants (A-H-l-B). However, formation of the products (A + B-H) from the transition state is an irreversible step. 

C18-0119. In a biochemistry laboratory, you are asked to prepare a buffer solution to be used as a solvent for isolation of an enzyme. On the shelf are the following solutions, all 1.00 M formic acid (Za = 1.8 X 10 ), acetic acid = 1.8 x 10 ), sodium formate (NaHC02), and sodium acetate (NaCH3 CO2). Describe how you would prepare 1.0 L of a pH = 4.80 buffer solution...
