| Molecular structure of Chlorophyll b |
Chlorophyll is a green pigment absorbing light most strongly in the blue portion of the visible spectrum. This molecule is also known as a Photo-receptor. Chlorophyll has Carbon, Hydrogen, Oxygen, Nitrogen and Magnesium atoms. It has a Nitrogen ring at the top with a Magnesium atom center. This structure is also called Porphyrin Ring. As you see in the picture, porphyrin ring has alternating single and double bonds. Sidechains attached to the ring structure determines the type of the compound. The long hydrocarbon tail anchors the chlorophyll to the thylakoid membrane.
