Carbon

Carbon is basic element of organic compounds. carbon have central position in the skeleton of life because of its unique characteristics.

Properties of carbon:

Tetravalent:   

                         It is tetravalent element. It react with other elements by forming covalent band (sharing of electrons). Carbon atom combine with four atoms of other elements by  symmetrically arrangement, in the result give stable configuration. because of this propety of tetravalency, carbon atoms synthesis complicated cellular structures.   

 Stable chain and rings: 

                      Carbon atoms combine to form stable rings, branched and unbranched molecules. This property of carbon is very responsible for the vast verity of inorganic molecules. The base of organic molecule is C-C bond.

Source of energy:

                  In cellular activities C-H band is the potential source of energy i.g, cellulose, protein, fats etc.

Peptide bond: 

                      C-N bond in amino acid linkage to form peptide bond and form protein.

Give stability to complex molecules:

                   C-O bond in glycosidic linkages provide stability to complex carbohydrate.
