Science > Chemistry > Biomolecules > Proteins and Their Classification The name protein (proteios Greek = pre-eminent or first) was first suggested, in 1838, by a Swedish chemist Berzelius to a Dutch chemist Mulder, who referred it to the complex organic nitrogenous substances found in the cells of the living beings. They are naturally occurring nitrogenous polymers of different alpha-amino […]

Science > Chemistry > Introduction to Organic Chemistry > Chemistry of Carbon Compounds Organic chemistry is a branch of chemistry, which studies carbon compounds. Organic substances are substances derived from organisms like plants and animals. In the olden days it was assumed that these substances cannot be prepared in laboratories. Berzelius assumed that some vital […]
