Vedclass · Answer

(A) Chlorophylls are magnesium porphyrin compounds. Chlorophyll-$a$ $(C_{55}H_{72}O_{5}N_{4}Mg)$ and chlorophyll-$b$ $(C_{55}H_{70}O_{6}N_{4}Mg)$ both consist of a magnesium porphyrin head,which is hydrophilic,and a phytol tail,which is lipophilic.Chlorophyll-$b$ differs from chlorophyll-$a$ only in one of the functional groups bonded to the porphyrin ring.Specifically,in chlorophyll-$b$,there is a $-CHO$ (aldehyde) group instead of a $-CH_{3}$ (methyl) group at the third carbon atom in the second pyrrole ring.
