Draw the condensed structural formula for a triacylglycerol that contains stearic acid and glycerol.

Short Answer

Expert verified

The condensed structural formula for a triacylglycerol that contains stearic acid and glycerol.

Step by step solution

01

Given data

The condensed structural formula for a triacylglycerol that contains stearic acid and glycerol.

02

An Introduction

Triacylglycerols are the predominant form of dietary lipids found in fats and oils, whether derived from plants or animals. Triacylglycerols are composed of three fatty acids

03

Determine the condensed structural formula for a triacylglycerol that contains stearic acid and glycerol. 

The given triacylglycerol contains stearic acid and glycerol.

Glycerol is a 3 carbon long chain with a hydroxy group on each carbon.

Stearic acid has 18 carbon long saturated and unbranched chain with a carboxyl group on the 1st carbon.
