I am a student pursuing bachelors in chemistry; Chemistry is an interesting subject but not that easy to study and difficult to understand the composition, structure, properties and chemical reactions. Chemistry is the scientific study of interactions of chemical substances that are constituted of atoms or the subatomic particles like protons, electrons and neutrons. Chemistry is often called the central science because it connects the other natural sciences such as physics, biology, and geology

Biotechnology: Chemistry goes green

Behind the scenes, industrial biotechnology is getting going at last
IS GREEN chemistry ready for take-off? Delegates at a big conference on “industrial biotechnology” held near Washington, DC, this week by Bio, the industry’s umbrella organisation, seemed to think so. Industrial biotech uses agricultural feedstocks, rather than petroleum-based ones, to produce chemicals, plastics and fuels. McKinsey, a consultancy, says global industry revenues will grow from €116 billion ($170 billion) in 2008 to as much as €450 billion by 2020. The World Economic Forum reckons the coming boom in “biorefineries” will create new markets worth almost $300 billion by 2020.
Industrial biotech seems to have been relatively unscathed by the financial crisis. Codexis, an American start-up backed by Royal Dutch Shell, an Anglo-Dutch oil giant, pulled off a stockmarket flotation in April. Amyris, another American start-up, secured an investment of around $130m from Total, a French oil firm, this week and is likely to go public soon too. …
