Structure of chlorophyll
Chlorophyll is the most widespread pigment in green plants. It is a porphyrin derivative with magnesium ion in the central chemical structure of chlorophyll. Chlorophyll is a tetrapyrrole with four nitrogen and carbons. Tetrapyrrole, along with central magnesium ion, forms a porphyrin ring. Types of complexes present in the thylakoid membrane: Photosystem I: Reaction centre consists of Chlorophyll a with maxim absorption at 700 nm Photosystem II: Reaction centre consists of Chlorophyll a with maxim absorption at 680 nm Cytochrome b6f (cyt b6f) complex: involved in electron transport chain. ATP synthase: involved in ATP synthesis
