Concept explainers
The example of a silyl–Hilbert–Johnson nucleosidation reaction in Section 25.3 is presumed to involve an intermediate ribosyl cation that is stabilized by intramolecular interactions involving the C2 benzoyl group. This intermediate blocks attack by the heterocyclic base from the

- The enzyme that catalyzes the C-Cg bond cleavage reaction that converts serine to glycine removes the substituent (R) bonded to the a-carbon in the first step of the reaction. Starting with PLP bound to serine in an imine linkage, propose a mechanism for this reaction. (Hint: The first step involves removal of the proton from serine's OH group.)arrow_forward5-Bromouracil (BU) resembles thymine sufficiently that BU base-pairs readily with adenine in a DNA helix, and it can readily substitute for thy- mine in DNA replication. However, its electron distribution allows it to resemble cytosine sufficiently that BU can pair with guanine. Show how a few rounds of replication in the presence of BU could convert an A-T base pair to G-C, and identify the products of each round of replication.arrow_forwardUnder acidic conditions (catalytic amount of acid) in anhydrous methanol, D-galactose can be converted to the methyl galactopyranoside X on the right side of the reaction arrow.

- Please give the resulting product of the reaction between ribose sugar and the fluorinated pyrimidine (denoted by a starred reactive nitrogen). What type of starting sugar is this ? α (Alpha) or β (beta)arrow_forwardResearchers analysed a glycopeptide (a peptide carrying one or several oligosaccharide groups) and determined both the sequence of the peptide and the sequence of the sugar molecule. The latter was identified as a diholoside coupled to the peptide by an osidic bond. The systematic name of this sugar is: B-D-glucopyranosyl-(1→4)-ß-D-galactopyranose. : Represent the chemical formula of this diholoside in a way that all oses are Question 1 represented according to the Haworth convention. Apart from the furane and/or pyrane cycles all atoms of this molecule must be given.arrow_forwardWhat does the "alpha" indicate in "α-D-ribofuranose"? It is the first anomeric form. The sugar is "right-handed." It is the dominant form of the possible forms of D-ribofuranose. The position of the C1 -OH group relative to the plane of the ring. None of these.arrow_forward
- Give reasons which option is correct. And give reasons why other options are incorrect. Note:- Hand written solutions are strictly prohibitedarrow_forwardAn important technique for establishing relative configurations among isomeric aldoses and ketoses is to convert both terminal carbon atoms to the same functional group. This can be done either by selective oxidation or reduction. As a specific example, nitric acid oxidation of d-erythrose gives meso-tartaric acid . Similar oxidation of d-threose gives (2S,3S)-tartaric acid. Given this information and the fact that d-erythrose and d-threose are diastereomers, draw Fischer projections for d-erythrose and d-threose.
