why nitrogen is important in human which molecules contain nitrogen

Nitrogen is one of the important elements found in living organisms. Supply of nitrogen from the atmosphere is maintained. Nitrogen is an essential constituent of amino acids and hence the proteins cannot be absorbed by the plants directly from the atmosphere..

Fertilisers that contain the macronutrient nitrogen come under this group. Example: Ammonium sulphate, ammonium nitrate, sodium nitrate, ure..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soi..

Nitrogen is present in the elemental state in the atmosphere to the extent of about 78% by volume. Nitrogen is important for life processes in all living organisms. But, free nitrogen cannot be directly assimilated by the living cells. Therefore, it is desir..

Nitrogen is an important structural component of many necessary compounds, particularly proteins. Atmosphere is the reservoir of free gaseous nitrogen and nitrogen compounds are found in bodies of organisms and in the soil. Living organisms cannot pickup elem..

(i) Nitrogen is a colorless, odorless, tasteless, neutral gas, which neither burns nor supports combustion. (ii) Burning magnesium ribbon Take nitrogen gas in a jar containing a small quantity of hot water. Introduce a burning magnesium ribbon into the jar. Allow the r..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..

. Plants convert the inorganic nitrates to organic proteins. The proteins from the plants enter the body of animals in form of food. C) How is nitrogen returned to the soil? When plants and animals die their bodies decompose. The organic proteins undergo a series of chemical changes, brou..

Summary - Nitrogen is the first member of group VA. Nitrogen has 5 electrons in its valence shell. It has a valency of 3 with respect to hydrogen and a valency upto 5 with respect to oxygen. It is a non-metal and its oxides are acidic in nature. Nitrogen is an imp..

Large amounts of free atmospheric nitrogen is however, fixed artificially by a number of methods. Three important methods ar..
