Interpretation Introduction

Interpretation:

The number of methylmalonates involved in the biosynthesis of 6-deoxyerythronolide B are to be determined.

Concept introduction:

In the structure of 6-deoxyerythronolide B, methyl malonate is one of the sources of the methyl group.

This methyl group is attached to the alpha carbon atom of the carbonyl C=O or the carbon atom bearing an oxygen functional group -C-O- .

When methyl malonate is used in the biosynthesis of a compound, methyl malonates can be identified as fragments having the CH3-C-C-OH connectivity.

Prostaglandins are a class of eicosanoids, fatty acid derivatives with a variety of extremely potent actions on vertebrate tissues. They are responsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20- carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. This enzyme, a cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins. Rate of formation of PGG2 with 10 mg/ml ibuprofen (mM/min) Arachidonic acid (mM) Rate of formation of PGG2 (mM/min) 0.190 12.3 0.228 13.9 0.342 17.5 0.570 1.33 22.2 28.8 7.71 8.88 11.9 16.3 24.0 The kinetic data given in the table are for the reaction catalyzed by a mutant of prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. Vmax Km = mM/min mM
d-Glucuronic acid is found widely in plants and animals. One of its functions is to detoxify poisonous HO-containing compounds by reacting with them in the liver to form glucuronides. Glucuronides are water soluble and, therefore, readily excreted. After ingestion of a poison such as turpentine or phenol, the glucuronides of these compounds are found in urine. Draw the structure of the glucuronide formed by the reaction of beta-d-glucuronic acid and phenol.
Isoerythrogenic acid, C18H26O2, is a acetylic fatty acid that turns vivid vle on exposure to UV light. On Catalytic hydrogenation over a palladium catalyst, five molar equivalents of hydrogen are absorbed, and stearic acid
