Chapter 15: Q. 15.34 (page 525)

Use line-angle formulas to write the balanced chemical equation for the acid hydrolysis of glyceryl trioleate (triolein).

Short Answer

Expert verified

The balanced chemical equation for the hydrolysis of glyceryl trioleate acid is

Step by step solution

01

Introduction.

Fats, waxes, sterols, triglycerides, and other naturally occurring molecules are examples of lipids.

Triglycerides are lipids that comprise glycerol bound to three fatty acids, such as fats and oils.

The carbon chain in fatty acid is long and unbranched, with a carboxylic acid end group.

02

Given Information.

Write a balanced chemical equation for the acid hydrolysis of glyceryl trioleate using line-angle formulas (triolein).

03

Explanation.

Three fatty acids are formed when triacylglycerols are hydrolyzed in the presence of strong acids such as HClor H2SO4glycerol.

The balanced chemical equation for the hydrolysis of glyceryl trioleate acid is

What are some of the different kinds of lipids?

The plastic known as PETE (polyethyleneterephthalate) is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. PETE is made from terephthalic acid and ethylene glycol. Today, PETE is the most widely recycled of all plastics. In one year, 1.5×109lbof PETE is recycled. After it is separated from other plastics, PETE can be used in polyester fabric, doormats, and tennis ball containers. The density of PETE is 1.38g/ml.

a. Draw the line-angle formula for the ester formed from one molecule of terephthalic acid and one molecule of ethylene glycol.

b. Draw the line-angle formula for the product formed when a second molecule of ethylene glycol reacts with the ester you drew in part a.

c. How many kilograms of PETE is recycled in one year?

d. What volume, in litres, of PETE is recycled in one year?

e. Suppose a landfill holds 2.7×107L of recycled PETE. If all the PETE that is recycled in a year were placed instead in landfills, how many would it fill?
