Understanding the Occurrence of Natural Phospholipids In problem 1 (b) ill Chapter 8, you weft asked to draw all the possible phosphate-dylserme isomers that form be formed from palmitic and linolenie acids. Which of the PS isomers aft not likely ll> be found in biological membranes?

Interpretation:
The PS isomer which is not likely to be found in biological membranes should be determined.
Concept Introduction:
There are two wide kinds of isomers: stereoisomers and constitutional.
Constitutional isomers vary in connectivity and bonding, whereas stereoisomers vary in 3-D orientation.
Answer to Problem 1P
Two structures having linolenic acid is connected to the initial carbon and palmitic acid is attached to the second carbon.
Explanation of Solution
Lipid is in proximity within biological membranes. Formation of double bond results in the bend in the chain which creates space among lipids.
Phosphatidyl serine molecules contain the big group on glycerol’s third carbon. Due to this group, the 2nd and 3rd carbons of glycerol contain more space as compared to the first carbon.
The fatty acid that attaches to the first carbon is usually a saturated fatty acid. An unsaturated fatty acid attaches to the second carbon.
Phosphatidylserines contain the phosphate bond in the serine residue on the 3rd carbon of glycerol.
Linoleic acid contains two common forms, thus, there are four kinds of different phosphatidylserines created with linoleic and palmitic acid.
The structure is shown as follows:
