About This Book

Biochemistry and Oral Biology presents a unique exposition of biochemistry suitable for dental students. It discusses the structural basis of metabolism and the general principles of nutrition. It addresses the soft tissues, hard tissues, and the biology of the mouth. Some of the topics covered in the book are the free radical production; scope of biochemistry; characteristics of atoms; structure and properties of water; molecular building materials; ionization of proteins; affinity chromatography of proteins; structural organization of globular proteins; classification of enzymes; and biochemically important sugar derivatives. The naturally occurring fatty acids are fully covered. The nucleic acid components are discussed in detail. The text describes in depth the energy equivalents of different nutrients. The physiological effects of dietary fiber vitamin D deficiency are completely presented. A chapter is devoted to the alternative methods of fluoride administration and description of vitamins. The book can provide useful information to dental students, and researchers.

Frequently asked questions

How do I cancel my subscription?
Simply head over to the account section in settings and click on “Cancel Subscription” - it’s as simple as that. After you cancel, your membership will stay active for the remainder of the time you’ve paid for. Learn more here.
Can/how do I download books?
At the moment all of our mobile-responsive ePub books are available to download via the app. Most of our PDFs are also available to download and we're working on making the final remaining ones downloadable now. Learn more here.
What is the difference between the pricing plans?
Both plans give you full access to the library and all of Perlego’s features. The only differences are the price and subscription period: With the annual plan you’ll save around 30% compared to 12 months on the monthly plan.
What is Perlego?
We are an online textbook subscription service, where you can get access to an entire online library for less than the price of a single book per month. With over 1 million books across 1000+ topics, we’ve got you covered! Learn more here.
Do you support text-to-speech?
Look out for the read-aloud symbol on your next book to see if you can listen to it. The read-aloud tool reads text aloud for you, highlighting the text as it is being read. You can pause it, speed it up and slow it down. Learn more here.
Is Biochemistry and Oral Biology an online PDF/ePUB?

Introduction

Publisher Summary

The aims of biochemistry are to describe the nature of living forms and living processes in terms of chemistry and physics. Biochemists believe that the existence and activities of living organisms are explained on the basis of the interaction of their component molecules. These are divided very broadly into two groups, namely, small molecules and macromolecules. The main types of macromolecule are proteins, nucleic acids, and polysaccharides, all of which are long, chain-like molecules built up from a large number of linked subunits. These biopolymers tend to associate into still larger complexes with other molecules that may or may not be of the same type. The small molecules act not only as the building units from which macromolecules are synthesized but also as sources of energy, messengers, and regulators. Macromolecules are the essential basis of the elaborate structures in and around which the life processes occur; they also control and regulate these processes. Thus, macromolecules are responsible for the energy exchanges and chemical reactions that comprise metabolism for the irritability that enables the organism to respond to changes in its environment, for mobility, and for reproduction. The aims, attitudes, and techniques of biochemistry are as relevant to dentistry as to medicine or any other aspect of biology. Only when the normal structures of the mouth and their development and reactions are understood is it possible to appreciate the true nature of dental disease. All disease has a biochemical basis regardless of whether its origin is nutritional or genetic or it is caused by an infectious or toxic agent.
