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 uses oxygen to convert arachidonic acid to PGG2 (a prostaglandin). Ibuprofen inhibits this enzyme and is a fever reducer and anti-inflammatory agent. The kinetic data is given below...
1- Sucrose does not react with Fehling's reagent because A- Sucrose is not a reducing sugar. B) The anomeric carbon of glucose is involved in the glucose- fructose bond and hence is not free to form the aldehyde in solution. C) The monosaacharide constituents of sucrose no longer have an anomeric carbon with a free potential aldehyde or ketone group, and therefore no longer exhibits reducing properties. D) sucrose is a disaccharide of glucose and fructose in which the oxygen...
1. Which of the following is true? a. The main rate-limiting step for fatty acid breakdown is the transfer of the fatty acyl group to carnitine, with release of CoA. b. Elongase activity is an enzyme functionality of fatty acid synthase that adds 2-carbon acetyl groups to increase the length of palmitate. c. Oligomycin directly inhibits Complex I in the electron transport chain d. Squalene synthase catalyzes the rate-limiting step of fatty acid synthesis.

Can you help me identify reagent (i), Compound 8 and
Compound 12 in the reaction scheme?
You have laboratory data on all the compounds in the
synthesis, however the amount of data available to you varies. Some
have the entirety of the spectral data, others have as little as
the elemental analysis. Use the laboratory data to help you
discover which reaction has been performed.
The lab data for Compound 8 and 12 is as
follows:
You can use any...
