(a)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.
Concept introduction:
Phosphoglycerides are same as triglycerides but the only difference is that in triglycerides there are three fatty acid residues. But in phosphoglyceride one of the fatty acid residue in triglyceride is replaced by a phosphoester. Hydrolysis of phosphoglycerides yield glycerol, fatty acid, phosphate.
To draw: the structure of lecithin
(b)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.
Concept Introduction:
Chirality is the ability of the compound to rotate the plane polarized light when it is passed through them. A chiral center is the one when the carbon atom is attached to a four different groups. If the plane polarized light is rotated clockwise then the compound is said to be dextrorotatory and if it is anti-clockwise then the compound is levorotatory.
(c)
Interpretation:
Structure of lecithin and the naturally occurring enantiomer need to be drawn and if phosphodiester is in C2 position will there be chirality has to be discussed.
Concept Introduction:
Chirality is the ability of the compound to rotate the plane polarized light when it is passed through them. A chiral center is the one when the carbon atom is attached to a four different groups. If the plane polarized light is rotated clockwise then the compound is said to be dextrorotatory and if it is anti-clockwise then the compound is levorotatory. If the carbon is not attached to four different groups means then it is said to be achiral.

- NH2 1. CH3–MgCl 2. H3O+ ? As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C - C bond, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. This reaction will not make a product with a new C - C bond. Х ☐: Carrow_forwardPredict the major products of this organic reaction. If there will be no major products, check the box under the drawing area instead. No reaction. : + Х è OH K Cr O 2 27 2 4' 2 Click and drag to start drawing a structure.arrow_forwardLaminar compounds are characterized by havinga) a high value of the internal surface of the solid.b) a high adsorption potential.arrow_forward
