Include only the structure of the final products of the reaction.Which one is the most likely to be a catalytic triad of an enzyme that follows general acid base catalysis? -Glu-His-Cys -Leu-His-Ser -Glu-Phe-Ser -Asp-His-AlaAll sugar residues are in their D-isomeric forms. Is this trisaccharide a reducing sugar? Why or why not?
- Chain Shortening of monosaccharides can be done in the laboratory thru Kiliani-Fischer reaction. True FalseHistidine is frequently used as a general acid or base in enzyme catalysis. Considering the pKa value of the side chain, suggest a reason why is this so?true or false: Pyrimidine synthesis involves the use of a molecule of N10-formyl tetrahydrafolate.
- Non-standard amino acids are derived from common amino acids by biochemical modifications. Please identify the chiral centers of given non-standard amino acids.When glucose is reduced, only one alditol is produced. When fructose undergoes the same reaction, however, two diasteriometric sugars are produced. Draw their structures.Give the full biochemical name for a D-aldopentose with the following pattern of chiral centers: carbon #2 = D, carbon #3 = D.
