Interpretation Introduction

To explain:

The formation from glycerol from stearic and arachidonic acid should be described.

Introduction:

Glycerol is the colorless, viscous liquids that belong to the organic group of alcohol. It has three carbon atoms and three hydroxyl groups in its structure that are known as trihydroxyl sugar alcohol.

Explanation of Solution

The chiral molecule is found in the second carbon of glycerol if there is the presence of different substitutes at both ends of carbon. This can lead to the formation of six triacylglycerols from stearic and arachidonic acids as below:

Interpretation Introduction

To explain:

The formation from phosphatidylserine isomers from palmitic and linolenic acids should be described.

Introduction:

A phospholipid with fatty acid is known as phosphatidylserine that covers and protects the cells in the brain and carries messages. It has two fatty acids attached with ester linkage to the C-1 and C-2 of glycerol and serine attached by a phosphodiester linkage to the C-3 of glycerol.

Explanation of Solution

There is a presence of phosphate bonded with a serine residue at C-3 of glycerol in structures of phosphatidylserine. There are two common forms of linolenic acid which means four different phosphatidylserine can be formed from palmitic and linolenic acids as shown below:
