Concept explainers
(a)
Interpretation:
Portion of the glycerol, sphingosine, fatty acid and choline molecules that is derived from structure A needs to be identified.
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.
(b)
Interpretation:
Portion of the glycerol, sphingosine, fatty acid and choline molecules that is derived from structure B should be identified.
Concept Introduction:
Sphingomyelin derived from sphingosine molecule which is connected to a fatty acid molecule and a phosphate containing alcohol molecule.
(c)
Interpretation:
Portion of the glycerol, sphingosine, fatty acid and choline molecules that is derived from structure C should be identified.
Concept Introduction:
Triacylglycerol contains one glycerol molecule and three fatty acid molecules bind with ester bonds.
