Molecular biology cell is the study of the constituents of the cells that are the basic unit of living organisms. These contents of cells; organic and inorganic are held together by chemical bonds and that is why biochemistry and molecular biology can be weaved into each other with none being different from the other. This article will take a brief look into molecular biology and give you a re rough ides of what you should expect.
Organic compounds in the cell are fats, protein carbohydrates and nucleic acids, the inorganic contents are water acids and bases. In a cell's molecular biology, you will learn the interrelationships between all the organic and inorganic compounds. Water forms a big chunk of most cells and is important for its qualities as a solvent and for the fact that it has surface tension. Water requires a lot of heat to raise its temperature and this quality of maintaining a steady temperature despite fluctuation is the reason why it is so important in the cells. Acids and bases are important to maintain the PH of the cell is kept at the neutral level
The carbohydrates are the principal sources of energy for both the human body cells and the plant cells. They come in the form of sugars and starch. A carbohydrate atom is made of carbon hydrogen and oxygen atoms in differing ratios. Simple sugars have simpler ratios and otherwise for the complex sugars. Monosaccharides are simple sugars and two of them may condense to form a disaccharide which will have a special name depending on its constituent monosaccharide. Disaccharides form polysaccharides which are complex sugars; insoluble in water and not sweet e.g. starch and glycogen. Fats are also made up of carbon hydrogen and oxygen atoms in different ratios and they too build up to provide energy to the body when it has used up its store of carbohydrates. Proteins are made up of amino acids, which are bonded together using polypeptide chains. Proteins form hormones and enzymes and also form keratin, which is used in the formation of nails and hair in the human body. In animals, it forms claws hooves feathers and fur.
Molecular biology will delve into the chemical reactions in the cells and especially those that cause the formation of the carbohydrates, lipids fats proteins and sugars. The energy that brings abound the chemical bonding will also be learnt in molecular biology.
