Excerpt from The Hydrolysis of Proteids: ThesisTo determine the constitution of these bodi s. Proteids are very widely distributed both throughout the plant and animal kingdoms and a definite knowledge of their chemistry would help greatly to understand the metabolic changes taking place in living organisms. The elements entering into the composition of the proteids are sulphur. They exist in an almost constant ratio in these bodies and they probably bear a similar structural relation to each other although it has not as yet been established what this relation is. The similarity in their chemical behavior tends to confirm the above statement.. 0 illustrate this structural relation between the different pro teide it may be said that all protein bodies possess neither strongly acid nor strongly basic properties but form salts with both acids and bases altlongh their affinities for either are very.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
