Drawing Structures of Triacylglycerols Draw the structures of (a) all the possible triacylglycerols that can be formed from glycerol with Stearic and arachidonic acid and (b) all the phosphatidylserine isomers that tan be formed from palmitic and linolenic acids.

(a)

Expert Solution

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:

Students have asked these similar questions

You were tasked with purifying an untagged transcription factor (molecular weight 65,000Da, isoelectric point unknown) from a contaminant Protein A (molecular weight 50,000 Da, isoelectric point 5.0). You were also instructed to use the protein for crystallization studies after purification.i) In the initial purification step, which type of chromatography should you attempt? Explain your choice and specify the requirements of the buffer solution you should use. ii) Analyzing the proteins recovered from step i) using SDS-PAGE, you still observed a faint band of Protein A in addition to the transcription factor band. Given the limited time available for further purification, you must choose ONE appropriate chromatography method to maximize the chances of separating the two proteins as well as your crystallization studies. Provide a detailed explanation of your selection and the techniques/strategies you would employ to achieve this.

You were given a mixture of two proteins with different isoelectric points and molecular weights:• Protein X: pI 4.2, MW 42,000• Protein Y: pI 9.8, MW 90,000Using a Tris-glycine discontinuous native gel (pH8.3) electrophoresis system with a running gel of 12%, only a single band was observed upon protein staining after electrophoresis. Explain the observed result and discuss possible factors affecting protein migration in this system.
