叶绿素（Chlorophyll） Chlorophyll Chlorophyll The green pigment found in photosynthetic membranes, the major component of light trapping in photosynthesis, and the most important pigment related to photosynthesis (photosynthesis). Photosynthesis is the process of converting light energy into chemical energy by synthesizing some organic compounds. Chlorophyll is found in virtually all photosynthetic organisms, including green plants, prokaryotic blue-green algae (Cyanobacteria), and eukaryotic algae. Chlorophyll absorbs energy from light, and energy is used to convert carbon dioxide into carbohydrates. There are several different types, chlorophyll a and B are the main types in higher plants and green algae; chlorophyll C and D in all kinds of algae, and chlorophyll a coexist; chlorophyll c rare, found in some algae found in some bacteria; bacterial chlorophyll. In green plants, chlorophyll is found in a membranous disk unit called the organelle of the chloroplast (thylakoid). The chlorophyll molecule contains a central magnesium atom, a nitrogen containing peripheral structure, called porphyrin ring; a long carbon hydrogen side chain (called phytol chain) connected to the porphyrin ring. The difference in chlorophyll species is caused by minor changes in some of the lateral bases. Chlorophyll is structurally similar to heme, which is found in the red blood cells of mammals and other vertebrates to carry oxygen. Chlorophyll is two chlorin (chlorin) pigment, structure and porphyrin (porphyrin) pigment such as heme like. There is a magnesium atom in two chlorin ring central. Chlorophyll has many lateral chains and usually includes a long base (phytyl, chain). Here are some of the chlorophyll found in nature: Chlorophyll is involved in the global carbon cycle Japan found that chlorophyll D could affect the global carbon cycle. Tokyo in August 2008, a Japanese research team in the new issue of the U.S. science magazine reported that one can make the photosynthesis in the near
