Vedclass · Answer

(C) Chlorophyll $a$ is the primary photosynthetic pigment found in plants,algae,and cyanobacteria.Its chemical structure consists of a porphyrin ring with a central magnesium $(Mg)$ atom and a long phytol tail.The molecular formula for chlorophyll $a$ is $C_{55}H_{72}O_5N_4Mg$.In contrast,chlorophyll $b$ has the formula $C_{55}H_{70}O_6N_4Mg$,where a methyl group $(-CH_3)$ in chlorophyll $a$ is replaced by an aldehyde group $(-CHO)$.

The molecular formula of chlorophyll $a$ is........
