Glycerol functional groups pdf
Webthe ester functional group. The carbon carbonyl is bonded to 2 electronegative oxygen atoms, making it electron poor and so an electrophilic center. The oxygen if methanol has 2 lone pairs of electrons, making it a nucleophile. Before nucleophilic substitution can take place, the alkoxide oxygen on the ester must be WebPhospholipids are molecules that form the cell membrane. They consist of a polar phosphate head group and two nonpolar fatty acid tails joined by a glycerol backbone. The phosphate group can link with different molecules, such as serine or choline, to generate diverse kinds of phospholipids. The fatty acid tails can have cis or trans double ...
