Principles of biochemistry / H. Robert Horton [et al.] Horton, H. Robert [et al] [ electronic resource] - 5th ed. [electronic resource] - 4th ed. Upper Saddle. Principles of Biochemistry, 4th Edition. Robert A Horton, North Carolina State University. Laurence A. Moran, University of Toronto. Gray Scrimgeour, University . My class uses the 5th edition of this book, but we were told by the professor that the 4th edition and the international edition are the exact same text, just different .

Perry trained at the University of Colorado, where he studied sex determination in the nematode C.

In he returned to the University of Toronto as a faculty member in the Department of Molecular and Medical Genetics. His research has focused on developmental genetics, meiosis, and bioinformatics.

In he joined the Ontario Institute for Cancer Research. Moran, University of Toronto.

Principles of Biochemistry, 4th Edition

The remaining problems were created by Drs. Robert N. De Abreu of the University of Toronto. Over the past years biochemists have discovered that the same chemical compounds and the same central metabolic processes are found in organisms as distantly related as bacteria, plants, and humans.

It is now known that the basic principles of biochemistry are common to all living organisms.

Although scientists usually concentrate their research efforts on particular organisms, their results can be applied to many other species. This book is called Principles of Biochemistry because we will focus on the most important and fundamental concepts of biochemistry—those that are common to most species.

Where appropriate, we will point out features that distinguish particular groups of organisms. Many students and researchers are primarily interested in the biochemistry of humans. The causes of disease and the importance of proper nutrition, for example, are fascinating topics in biochemistry. However, we will also try to interest you in the biochemistry of other species.

As it turns out, it is often easier to understand basic principles of biochemistry by studying many different species in order to recognize common themes and patterns but a knowledge and appreciation of other species will do more than help you learn biochemistry. It will also help you recognize the fundamental nature of life at the molecular level and the ways in which species are related through evolution from a common ancestor.

Perhaps future editions of this book will include chapters on the biochemistry of life on other planets.

Until then, we will have to be satisfied with learning about the diverse life on our own planet.

We begin this introductory chapter with a few highlights of the history of biochemistry, followed by short descriptions of the chemical groups and molecules you will encounter throughout this book.

The second half of the chapter is an overview of cell structure in preparation for your study of biochemistry. Anything found to be true of E.

Viruses consist of a nucleic acid molecule surrounded by a protein coat. The period before saw rapid advances in the understanding of basic chemical principles such as reaction kinetics and the atomic composition of molecules.

Many chemicals produced in living organisms had been identified by the end of the 19th century. Since then, biochemistry has become an organized discipline and biochemists have elucidated many of the chemical processes of life.

The Autobiography of Malcolm X: As Told to Alex Haley

The growth of biochemistry and its influence on other disciplines will continue in the 21st century. Eduard Buchner — Today we understand that the synthesis and degradation of biological substances obey the same chemical and physical laws as those that predominate outside of biology. Louis Pasteur — is best known as the founder of microbiology and an active promoter of germ theory. But Pasteur also made many contributions to biochemistry including the discovery of stereoisomers.

Two major breakthroughs in the history of biochemistry are especially notable—the discovery of the roles of enzymes as catalysts and the role of nucleic acids as information-carrying molecules. The very large size of proteins and nucleic acids made their initial characterization difficult using the techniques available in the early part of the 20th century. With the development of modern technology we now know a great deal about how the structures of proteins and nucleic acids are related to their biological functions.

The first breakthrough—identification of enzymes as the catalysts of biological reactions—resulted in part from the research of Eduard Buchner. In Buchner showed that extracts of yeast cells could catalyze the fermentation of the sugar glucose to alcohol and carbon dioxide.

Previously, scientists believed that only living cells could catalyze such complex biological reactions. Fischer studied the catalytic effect of yeast enzymes on the hydrolysis breakdown by water of sucrose table sugar.

He proposed that during catalysis an enzyme and its reactant, or substrate, combine to form an intermediate compound. He also proposed that only a molecule with a suitable structure can serve as a substrate for a given enzyme. Fischer described enzymes as rigid templates, or locks, and substrates as matching keys. Researchers soon realized that almost all the reactions of life are catalyzed by enzymes and a modified lock-and-key theory of enzyme action remains a central tenet of modern biochemistry.

Another key property of enzyme catalysis is that biological reactions occur much faster than they would without a catalyst. In addition to speeding up the rates of reactions, enzyme catalysts produce very high yields with few, if any, by-products.

Biochemical reactions must be more efficient because byproducts can be toxic to cells and their formation would waste precious energy.

The mechanisms of catalysis are described in Chapter 5. The last half of the 20th century saw tremendous advances in the area of structural biology, especially the structure of proteins.

The first protein structures were solved in the s and s by scientists at Cambridge University United Kingdom led by 1.

Kendrew and Max Perutz. Since then, the three-dimensional structures of several thousand different proteins have been determined and our understanding of the complex biochemistry of proteins has increased enormously. These rapid advances were made possible by the availability of larger and faster computers and new software that could carry out the many calculations that used to be done by hand using simple calculators.

Much of modern biochemistry relies on computers. The nonpathogenic strain was permanently transformed into a pathogenic strain.

This experiment provided the first conclusive evidence that DNA is the genetic material. Some of the questions at the end of the chapters provide a better biochemical connection than the text itself but may require greater understanding of metabolism and diseases than presented in the chapter.

For example, the entire second chapter is devoted to water. The content of this chapter is primarily presented as in a standard general chemistry textbook with a minor emphasis on biological fluids. At least two questions at the end of this chapter require some understanding of words such as respiratory and metabolic acidosis. Greater emphasis on similar concepts could have been provided in the chapter. Common metabolic diseases are presented in the boxes in the chapters related to metabolism.

There is some attempt made to discuss the cellular organelles in which the reactions are occurring and if prokaryotes and eukaryotes share similar pathways.

There is no clear discussion on movement of chemicals in and out of organelles.

Although the authors claim to have made the chemistry behind the chemical reactions clearer for students such that memorization of the concepts is not required, the text does not seem significantly different from other similar texts. There is some attempt at simplifying math. For a chemically oriented book, bioenergetics could have received a greater emphasis.

In the final chapter on DNA recombinant technology, various cloning vectors are discussed along with a brief discussion of genomic libraries and cDNA libraries. Expression of proteins and application of recombinant technologies are also briefly presented.

Even though genetic engineering concepts are presented, no controversial discussions on these topics are discussed. As is typical of most science texts, there is some attempt to present historical data but no attempt to highlight anyone other than the usual suspects.

Overall, it is a decent book for teaching undergraduate biochemistry in the standard format.Passage weather as up am exposed. As it so contrasted oh estimating instrument. Continuing interested ten stimulated prosperous frequently all boisterous nay.
