The name protein was first proposed by mulder. Proteins are formed from simpler unit called amino acids. They are an important constituent of cells and tissues. All protein is composed of carbon, hydrogen, oxygen, nitrogen and some amount of sulphur and phosphorous. Pulses are the rich source of protein. Soyabeen has more protein content than any other pulses.
