An inspiring success story

Venkataraman Ramakrishnan is an Indian born American. He was honoured with Nobel prize in Chemistry in the year 2009 along with two others for his work in ribosomes. He has also published a few scientific journals on ribosomes and its structure as co-author.

He was born in cuddalore, Tamil Nadu in a middle class family. His parents were scientists and lecturers in biochemistry. Being from an science background, he naturally developed interest in science.He did his graduation in Physics in 1971.He pursued his higher studies in America and obtained his Ph.D in Physics from Ohio University.

He started his research work on ribosomes from 1983. He has also determined the complete structure of ribosomes along with the tRNA and mRNA. He was awarded with Padma Vibhushan in 2010 for his work in science. Presently he is the President of the Royal Society.

The future in biomolecular catalysts

Bio-catalysts or biomolecular catalysts are the enzymes which determine the rate of biological reactions. These catalysts help in speed up or slow down the reaction rate. They work under optimum pH and temperature and are highly sensitive to pressure and solvent. These biocatalysts are highly selective and specific in nature.

Bio catalysts is an important topic in the field of chemistry. Researches are being carried out in engineering these bio molecular catalysts to increase their utilization. These catalysts are an important part of our body system as they carry out many vital biological reactions.

Researches are being carried out with an aim to achieve enzyme like activity in lab. The growth of bio materials chemistry has caused important developments including new methods to arrange enzyme in arrays. The advantage of developing engineered catalysts is that they do not contain rare or expensive metals and do not require organic solvents.

The important use of development of bio molecular catalysts is the production of hydrogen as an ecofriendly fuel. It requires catalysts capable of efficient aqueous proton reduction. Chemists are working on how to deliver electrons and protons to and from catalyst active sites that perform redox reactions. If we succeed in developing these engineered bio catalysts, the traditionally used fuels can be replaced by hydrogen which is more efficient and sustainable.
