In this article we will discuss about the molecular structure of proteins with the help of diagrams. Quantitatively, proteins are the chief organic components of most living organisms, as also of viruses. About 50% of the dry weight of bacterial cells is protein. The flagella, pili and fimbriae are made up entirely of proteins, and the cell membrane, cytoplasm, ribosomes [...]
In this article we will discuss about the molecular structure of carbohydrates with the help of diagrams. Carbohydrates are organic compounds consisting of carbon, hydrogen and oxygen. They are present in all cellular organisms. The simple carbohydrates, known as monosaccharides, contain the three component elements C, H and O of which H and O are in the same ratio as [...]
The below mentioned article provides notes on autotrophic metabolism. Autotrophy generally means the ability of organisms to use inorganic carbon in the form of CO2 as the sole source of carbon for synthesizing organic compounds necessary to build cell components. This ability is also sometimes called carbon-autotrophy to distinguish the ability of some organisms to use molecular nitrogen as the [...]
