Abstract

The name protein is taken from the Greek "proteios", which means "first." This name is indeed well chosen, for proteins are the substance of life. Chemically, proteins are high polymers, and a simple protein molecule may contain hundreds or thousands of the twenty-odd amino acid units. Hence the possibilities for variation in protein structure are almost infinite.
