Concept explainers
(a)
Interpretation:
Structures which are aligned with phospholipid should be identified from the given block diagrams.
Concept Introduction:
A phospholipid has a phosphorus atom in its lipid structure. Two types of phospholipids are available; phosphoacylglycerols and sphingomyelins.
Phosphoacylglycerols consist of two fatty acids, one phosphate group bonded with low molecular weight alcohol and one glycerol molecule in the structure.
Sphingomyelin derived from a sphingosine molecule that connects to a fatty acid molecule and a phosphate-containing alcohol molecule.
(b)
Interpretation:
Structures that are aligned with triacylglycerol should be identified from the given block diagrams.
Concept Introduction:
Simple triacylglycerol contains one glycerol molecule and three fatty acid molecules bind with ester bonds.
(c)
Interpretation:
Structures which are aligned with hydrolyzable lipid should be identified from the given block diagrams.
Concept Introduction:
In the presence of acid, base or enzyme, triacylglycerol molecules cleave the ester bonds in it and form fatty acids and glycerol.
(d)
Interpretation:
Structures that are aligned with sphingomyelin should be identified from the given block diagrams.
Concept Introduction:
Sphingomyelin derived from a sphingosine molecule that connects to a fatty acid molecule and a phosphate containing alcohol molecule.
(e)
Interpretation:
Structures that are aligned with phosphoacylglycerol should be identified from the given block diagrams.
Concept Introduction:
Phosphoacylglycerols consist of two fatty acids, one phosphate group bonded with a low molecular weight alcohol and one glycerol molecule in the structure.
