Which metallic element is found in chlorophyll

Its name is derived from the Greek word for the mineral beryl, beryllo. It is found in the Earth's crust at a concentration of 2. Gemstone-quality beryls include emeralds and aquamarine; the green color of these gems comes from trace amounts of chromium.

Because of its small size and high charge density, beryllium bonds through covalent bonding instead of ionic bonding. Elemental beryllium is very unreactive towards air and water, even at high temperatures. Beryllium is used to make windows for X-ray tubes it is transparent to X-rays , and is used in alloys with other metals, such as copper and nickel, to make spark-proof tools and watch springs.

Beryllium is also using in casings for nuclear weapons and in nuclear power plants because of its ability to reflect neutrons. Beryllium accumulates in bones; long-term exposure to beryllium results in inflammation in the lungs and shortness of breath a condition called berylliosis.

Magnesium is a silver-white, relatively soft metal. The name of the element is derived from Magnesia, a district in Thessaly in central Greece. Large amounts of magnesium are also present in the minerals in the Earth's mantle. Magnesium alloyed with aluminum and traces of other metals is used in car and aircraft construction; magnesium alloys are also used in other lightweight devices, such ladders, cameras, bicycle frames, hard disk drives, etc.

Magnesium is more easily oxidized than iron, and is used in sacrificial anodes to protect iron pipes and other structures that corrode easily. Magnesium burns in air with a brilliant white flame , and is used in fireworks and incendiary bombs. It used to be used in disposable flashbulbs, but this use has been supplanted by other types of illumination. Magnesium fires are very difficult to put out, since even in the absence of air, burning magnesium reacts with nitrogen to form magnesium nitride Mg 3 N 2 , and with water to produce magnesium hydroxide and hydrogen gas.

Magnesium is found in a number of familiar compounds. Magnesium hydroxide, Mg OH 2 , also known as milk of magnesia, is a laxative and antacid. The "milk" in "milk of magnesia" refers to the fact that since magnesium hydroxide is not very soluble in water, it tends to form a chalky, white suspension that looks like milk — but with considerably different physiological effects.

Green plants contain a molecule called chlorophyll , which consists of a flat ring of carbon and nitrogen atoms with a large open space in the middle, in which a magnesium ion is bound, held in place by the nitrogen atoms. The chlorophyll molecule absorbs light from the sun, and in the process of photosynthesis, the energy from the light is converted into chemical energy that the plant can use to power a multitude of processes.

In organic chemistry, magnesium reacts with bromoalkanes hydrocarbons containing carbon-bromine bonds to form organomagnesium compounds known as Grignard reagents after their discoverer, Victor Grignard, who won a Nobel Prize in Chemistry, These compounds are extremely useful in forming new carbon-carbon bonds, and are often used in the synthesis of organic compounds.

Let us see which mineral is present in chlorophyll. You should know that magnesium is the only mineral element present in chlorophyll, though there are certain particular elements like carbon, nitrogen, oxygen and hydrogen in composition of chlorophyll but are not considered as mineral elements. Magnesium is the central element present in the chlorophyll. The central magnesium atom in the chlorophyll is surrounded by a nitrogen- containing structure called a porphyrin ring.

The chlorophyll occurs in membranous disk- like units called the thylakoids, in organelles called chloroplasts. Magnesium metal present in chlorophyll absorbs light energy during the photosynthesis process. Thus, chlorophyll contains Mg. So, haemoglobin and chlorophyll contain Fe, Mg respectively. There are four types of chlorophyll: chlorophyll a, found in all higher plants, algae and cyanobacteria; chlorophyll b, found in higher plants and green algae; chlorophyll c, found in diatoms, dinoflagellates and brown algae; and chlorophyll d, found only in red algae.

The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide absorbed from the air and water into glucose, a type of sugar. The U. Food and Drug Administration FDA says that people over 12 years old can safely consume up to milligrams of chlorophyllin daily.

However you choose to consume chlorophyll, make sure you start at a lower dose and slowly increase only if you can tolerate it. Ethylene, a gaseous plant hormone, destroys chlorophylls, and it is occasionally used to degreen fruits. The acids naturally present, formed, or added to plant tissues during food processing convert the bright green chlorophylls to dull olive brown pheophytins by replacing the magnesium of the molecule with hydrogen.
