Publisher's Synopsis
Excerpt from The Hydrolysis of Proteids
Though the proteids form a class of organic compounds which is easily distinguished from the other great groups, like the fats, the oils, the carbohydrates, et oetera, yet no exact def inition of a proteid can be given. This is owing to the lim itations of our knowledge of both their composition and their structure. In regard to their composition it can be stated with certainty that the elements, carbon, hydrogen, oxygen, nitrogen, and sulphur are always present and in proportions varying, With in definite limits, and but slightly amongst the different pro teids. Our knowledge of their structure is very meagre, however, and is derived principally from studies of their decompos1tion products. These studies show that all proteids are closely associated in regard to both structure and chemical properties. It is not my purpose at this point, however, to discuss the pro teids in these particulars. In passing it will suffice to state concerning their structure, that the chief decozposition pro ducts are amido-acids of the aliphatic series, and concerning their chemical properties, that the proteids possess no very marked acid or basic properties, but form With both acids and bases, salts in Which the affinity for both the acid and base is very weak.
