(a)
Interpretation:
Two possible structures of cephalin need to be drawn 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 two possible structure of cephalins
(b)
Interpretation:
Two possible structures of cephalin need to be drawn 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.
