Concept explainers
(a)
Interpretation: The structural formula for the products obtained when the tripeptide, Thr–Leu–Ile undergoes complete hydrolysis under acidic conditions has to be stated.
Concept introduction: The complete hydrolysis of protein results into constituent amino acids. The component amino acids of the protein are obtained due to the breakdown of all the peptide bonds.
(b)
Interpretation: The structural formula for the products obtained when the tripeptide, Thr–Leu–Ile undergoes complete hydrolysis under basic conditions.
Concept introduction: The complete hydrolysis of protein results into constituent amino acids. The component amino acids of the protein are obtained since, all of the peptide bonds break.

- In solution, glucose exists predominantly in the cyclic hemiacetal form, which does not contain an aldehyde group. How is it possible for mild oxidizing agents to oxidize glucose?arrow_forwardIndicate whether the following pairs of monosaccharides are aldoses or ketoses. a. D-altrose & D-xylose b. D-arabinose & D-glyceraldehyde c. D-erythrulose & D-psicose d. D-talose & D-gulose e. dihydroxyacetone & D-tagatose f. D-idose & D-threosearrow_forwardDihydrouracil and β-ureidopropionate (N-carbamoyl–β-alanine) are intermediates in the conversion of uracil to β-alanine. Provide the structures of the molecules in this pathway.arrow_forward
- Given the following choices,a. what is the structure of the product of the reaction catalysed by ACAT?b. structure of the product produced from the reaction catalysed by phospolipase A2?c. general structure of TAGd. structure of glycerolarrow_forwardA glycolytic intermediate may be used to make the glycerol 3-phosphate necessary for the production of glycerophospholipids. For this conversion, provide a reaction sequence.arrow_forwardIdentify all the possible products when the tripeptide Ala-Val-Ala undergoes partial hydrolysisarrow_forward
- Draw out the steps in the synthesis of the dipeptide Ala–Gly.arrow_forwardDuring the inhibition of glycopeptide transpeptidase, a serine from the enzyme reacts with the amide carbonyl of the lactam ring in penicillin antibiotic to form an enzyme - penicillin complex which inactivates the enzyme. The conversion of an amide to an an ester is not normally observed in reactions of carboxylic acid derivatives. Provide an explanation as to why the amide of a penicillin antibiotic can react with the serine of glyopeptide transpeptidase in this unexpected way. The structure of amoxicillin, a penicillin antibiotic, is shown below: НО- OH H2N amoxicillin ..||Iarrow_forwardDuring the inhibition of glycopeptide transpeptidase, a serine from the enzyme reacts with the amide carbonyl of the lactam ring in penicillin antibiotic to form an enzyme - penicillin complex which inactivates the enzyme. The conversion of an amide to an an ester is not normally observed in reactions of carboxylic acid derivatives. Provide an explanation as to why the amide of a penicillin antibiotic can react with the serine of glyopeptide transpeptidase in this unexpected way.arrow_forward
- Draw the structures of the products formed by hydrolysis of the following tripeptide at physiological pH. Val-Gly-Ile Note: Reference the Naturally occurring amino acids data table for additional information. Click and drag to start drawing a structure.arrow_forwardisomaltose is a disaccharide which can be obtained by enzymatic hydrolysis of amylopectin. Deduce the structure of isomaltose from the following data: a. The hydrolysis of 1 mole of isomaltose with acid or alpha-glucosidase yields 2 moles of D- glucose. b. Isomaltose is a reducing sugar c. Isomaltose is oxidized with bromine water to isomaltonic acid. Insomaltonic acid methylation followed by hydrolysis yielded 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4,5- tetra-O-methyl-D-gluconate acid. d. Isomaltose methylation itself followed by hydrolysis to produce 2,3,4,6-tetra-O-methyl- D-glucose and 2,3,4-tri-O-methyl-D-glucose. Describe according to the four points abovearrow_forwardSalicylamides are inhibitors for an enzyme called scytalone dehydratase. SAR shows that there are three important hydrogen bonding interactions. Explain whether you think quinazolines could act as a bioisostere for salicylamides.arrow_forward
