CHLOROPHYLL Science is Fun in the Lab of Shakhashiri. The structure of one form, chlorophyll . a, is shown. (As you can see from the molecular structure, the “chloro” in chlorophyll does not mean that it contains the element chlorine. The chloro portion of the word is from the Greek . chloros, which means yellowish green. The name of the element chlorine comes from the same source. Chlorine is a yellowish green gas.) Chlorophyll is one of the, The chemical structure of flavonoids are based on a C. 15. skeleton with a CHROMANE ring bearing a second aromatic ring B in position 2, 3 or 4. Various subgroups of flavonoids are classified according to the substitution patterns of ring C. Both the oxidation state of the heterocyclic ring and the position of ring B are important in the classification. Examples of the 6 major subgroups are: 1.

The name chlorophyll was first coined by Pelletier and Caventou in 1818 but the chemical structure describing chlorophyll as magnesium complexes was obtained by Willstatter and Stoll in 1913. Chlorophyll is an important natural coloring agent used in the food industry. Chlorophyll is a true super nutrient. It is almost molecularly identical to our red blood cells, with the only difference being that it has a magnesium molecule at its centre instead of an iron molecule that our red blood cells have. It is this chemical structure which makes chlorophyll so

Chlorophyll in Plants. The chlorophyll molecule is the active part that absorbs the sunlight, but just as with hemoglobin, in order to do its job (synthesising carbohydrates) it needs to be attached to the backbone of a very complicated protein. The general structure of chlorophyll a was elucidated by Hans Fischer in 1940, and by 1960, when most of the stereochemistry of chlorophyll a was known, Robert Burns Woodward published a total synthesis of the molecule as then known.
