Is Oxalic Acid Necessary To Maintain Peristaltic Motion In Our Body?

oxalic-acid-foods-1Oxalic Acid belonging to the family of carboxylic acids and this chemical also termed as Ethanedioic Acid. Oxalic acid is widely used as an acid rinse in laundries, where it can able to remove rust and ink stains because of its capability of converting insoluble iron compounds into a soluble complex ion. For the same reason, it is the chief ingredient of many commercial preparations used for removing scale from automobile radiators. It occurs naturally in high levels in many common foods. Read More

Luncheon with chemicals? – take a break!!!!

Click chemistry applications in drug discovery


Click chemistry applications in drug discovery

click_chemistryClick chemistry is a chemical philosophy introduced by K. Barry Sharpless of The Scripps Research Institute, in 2001 and describes chemistry tailored to generate substances quickly and reliably by joining small units together. This is inspired by the fact that nature also generates substances by joining small modular units. Click chemistry is not a specific reaction; it is a concept that mimics nature. Click chemistry is a modular approach that uses only the most practical. Read More
