Glycogen and starch that are the form of carbohydrates remain stored in the body in the form of energy that were utilized during an emergency situation when no food is supplied to the body.

A ribonucleoprotein (RNP) is a complex of ribonucleic acid and RNA-binding protein. These complexes play an integral part in a number of important biological functions that include DNA replication, regulating gene expression and regulating the metabolism of RNA.

The combination of carbon, hydrogen and oxygen results in the production of fats. Fats, also known as triglycerides, are esters of three fatty acid chains and the alcohol glycerol.

Skeletal protein i.e. commonly known as actin and myosin are responsible to make up the various parts of the body along with maintaining the damage.

Cyanocobalamin (commonly known as Vitamin B₁₂ ) is the most chemically complex of all vitamins. Its chemical structure is based on a corrin ring, which, although quite similar to the porphyrin ring found in heme, chlorophyll, and cytochrome, has two of the pyrrole rings directly bonded.
