8:56 7 Expert Q&A Done refering a pic o fthedructure d ify the bal in the membrane lipid

Answer 1

(a) The observed structure is a phosphoglyceride, since it contains two fatty acid chains connected to alcohol which in turn is connected to the phospsphorlated amino acid. There is no sphingosine present in the structure.

(b) The alcohol present in the membrane lipid structure is glycerol.

(c) In order to increase the fluidity of the lipid a fatty acid of higher degree of unsaturation must be attached to the C2 of glycerol. As with more number of double bonds which a create a bend in the fatty acid structure leading to increase in its fluidity.

(d) Tm (melting temperature) of the membrane will decrease after such an alteration in the structure.

(e) The polar group given in the above membrane lipid is the amino acid which will make ionic bonds since amino acid usualy exist as zwitter ionic form or there may be formation of hydrogen bond between the Oxygen of the Carboxylic group of amino acid and Hydrogen of water.
