23. Lipids

Tell how many different products you would obtain on hydrogenation of the triacylglycerol in Problem 23.49 if:

a. One double bond was converted to a single bond

b. Two double bonds were converted to single bonds

c. Three double bonds were converted to single bonds

d. All four double bonds were converted to single bonds

Identify each of the following processes as hydrogenation, hydrolysis, or saponification and give the products:

a. the reaction of corn oil and hydrogen (H₂) with a nickel catalyst

Use condensed structural formulas to write the balanced chemical equation for the hydrogenation of glyceryl trilinolenate, a fat containing glycerol and three linolenic acid molecules.

One of the triacylglycerols in olive oil is glyceryl tripalmitoleate (tripalmitolein). (7.4, 7.7, 7.8, 8.6, 9.4, 15.3, 15.4) <IMAGE>

a. Draw the condensed structural formula for glyceryl tripalmitoleate (tripalmitolein).

 1.00 mole of glyceryl trioleate (triolein) is completely hydrogenated. (7.2, 7.3, 8.6, 15.3, 15.4)

a. Draw the condensed structural formula for the product.

Draw the structure of the product you would obtain on complete hydrogenation of the triacylglycerol in Problem 23.49. What is its name? Does it have a higher or lower melting temperature than the original triacylglycerol?
