The function of most chlorophyll (up to several hundred molecules per photosystem) is to absorb light and transfer that light energy to reaction centres. [1][2][3], It has a blue-green color and is an accessory pigment, particularly significant in its absorption of light in the 447–52 nm wavelength region. Abstract. wt. showed that chlorophyll was a mixture of two compounds, chlorophyll-a and chlorophyll-b: Chlorophyll- a (C 55 H 72 MgN 4 O 5 , mol.

The name comes from a combination of two Greek words, chloros, meaning "green" and phyllon, meaning "leaf." Chlorophyll c is unusual because it has a porphyrin ring structure and does not have an isoprenoid tail or a reduced ring D, features typical of the other chlorophylls commonly found in algae and plants. A universal set of equations for determining chlorophyll (Chl) a, accessory Chl b, c, and d, and total Chl have been developed for 90 % acetone, 100 % methanol, and ethanol solvents suitable for estimating Chl in extracts from natural assemblages of algae.

Chlorophyll c (Chl c) can be found in a number of organisms including nine Divisions of algae (chromophyte algae) as well as two Divisions of prokaryotes. Search results for chlorophyll at Sigma-Aldrich. Effects of chlorophyll and chlorophyllin on low-dose aflatoxin B(1) pharmacokinetics in human volunteers. Chlorophyll is the substance that enables plants to create their own food through photosynthesis. If possible, verify the text with references provided in the foreign-language article. Chlorophyll is not a single molecule: There are at least six varieties that have various side groups on the rings. Leaf samples (e.g. Chlorophyll is the name given to a group of green pigment molecules found in plants, algae, and cyanobacteria.
