Calcium is an important element on the earth.
Chemically it is a listed at 20 position in periodic table which is its atomic number.
It is classified as metallic element and its oxides are alkaline in nature.
It combines with many other elements to forms various compounds.
Calcium is one of the important substance man uses in daily life.
Calcium Uses in Everyday Life:
Calcium has many uses in our life. But it will be much clear if we read it in terms of different chemical forms and their uses. Also we can read it in terms of application in life.
Calcium uses in the body
- Body electrolyte: Calcium is a potent electrolyte in the body. It helps in conduction and maintenance of nervous signals and impulses in the body. The ion form of calcium is specially transmitted through pores called calcium channels in the cells and tissues. These channels are so important than many life saving drugs act through them to control the calcium and related physiology. So calcium is an indispensable body electrolyte. These are two hormones which control it levels in the body. These hormones include Parathormones, Vit-D.
- In bone formation: All the bones of the body either big or small or hard and soft are made of calcium. These bones are specifically formed from calcium phosphate (CaPO4).
- Tooth formation: Teeth present in the mouth for chewing are made of calcium. They are so hard to help breakdown food materials.
Calcium uses in plants:
calcium unlike in animals and humans has little but important uses in plants. It is a secondary nutrient and is essential for normal physiology and anatomy of plants.
It is part of cell wall contents of the plant cell. It forms calcium pectate which hold the surrounding cell walls together. Thus it help the cells to stay intact and gives rigidity and strength.
It is also involved in activation of few enzymes responsible for normal physiology.
Plants also from calcium oxalate crystals to detoxify calcium.
Calcium uses in other daily life activities.
In constructions: Calcium is an important substance used in construction since ages.
It is used as calcium carbonate, gypsum, plaster of parris etc.
Calcium carbonate is used in building material. This calcium carbonate is mixed with sand and water and used as binding material in between stones or bricks. This mixture dries up to become a hard mixture. Thus it holds the structure tight and rigid. It is currently less preferred due to fear of acid rains which melt away the alkaline calcium carbonate. But it said that construction made with it CaCO3 cooler than cement made structures.
Besides calcium carbonate due it alkaline property can be used a antacid and in food preparations to minimize acid. It is also used a calcium supplements in health care. Especially the organic calcium from oyster shell is preferred. But cheaper alternative is CaCO3.
Also CaCO3 is also used in making chalks, white washing of walls etc.
Gypsum is another compound made of calcium. It is highly used in giving smooth finish to walls. It is also used in making chalk piece and bricks for constructions. Gypsum is also used as fertilizers in agriculture.
Plaster of parris (bone break) statues is another form of gypsum. This is especially used for making sculptures.
Pearls are also formed by use of calcium by oysters.
