There are many different disciplines within the life sciences which are generally defined by the scale at which organisms are studied and the methods used to study them. For example Biochemistry is the study of the fundamental chemistry of life, Molecular Biology, examines complex molecular interactions and Cellular Biology investigates the basic building block of life, the cell.
Some of the Life Science fields that are attracting a lot of attention include:
Biotechnology. A very diverse area which involves the use of organisms and biological techniques to produce drugs and food. Examples of biotechnology drug products include antibiotics for bacterial infections and insulin for diabetes.
Genomics. The study of genes and their function. This involves the building of proteins from the information encoded by an organism’s DNA. Genomics has revealed thousands of new biological targets potentially leading to new drugs vaccines and diagnostic tests.
Proteomics. The study of proteins in an organism their interaction with each other. This may hold the key to curing diseases and identifying targets for drug development.
Some of the more common areas of the life sciences that provide useful products are:
Pharmaceutical chemistry. Combines the disciplines of chemistry and pharmacology for the development, manufacture and quality testing of drugs. It includes the identification and synthesis of potential new chemical entities and understanding their structure-activity relationships.
Food Science. The study of the characteristics of food in order to improve nutritional value, manufacturing processes and shelf life. The studies include the determination of the physical and chemical properties of foods and those of their constituent materials.
