Synopsis The science of Biomolecules is a composite subject and for satisfactorily expounding it, there is need to have full competence in both chemistry and biology, a combination what is usually rare. The present publication not only defines clearly the basic chemistry and biochemistry but also gives excellent insight into numerous applications to physiology, pathology and clinical medicine needed by the student. The publication attempts to provide the student and researcher in the field of Biomolecules, the basic approaches and issues involved in the developments and discoveries associated with the science. It will be of great value not only to the students but also to the teachers and researchers in the field of Biomolecules.
