Principles of Medical Biochemistry

• Broschiertes Buch

Produktbeschreibung

For nearly 30 years, Principles of Medical Biochemistry has integrated medical biochemistry with molecular genetics, cell biology, and genetics to provide complete yet concise coverage that links biochemistry with clinical medicine. The 4th Edition of this award-winning text by Drs. Gerhard Meisenberg and William H. Simmons has been fully updated with new clinical examples, expanded coverage of recent changes in the field, and many new case studies online. A highly visual format helps readers retain complex information, and USMLE-style questions (in print and online) assist with exam preparation.
Just the right amount of detail on biochemistry, cell biology, and genetics - in one easy-to-digest textbook.

Full-color illustrations and tables throughout help students master challenging concepts more easily.

Online case studies serve as a self-assessment and review tool before exams.

Glossary of technical terms, both in print and online. Clinical Boxes and Clinical Content demonstrate the integration of basic sciences and clinical applications, helping readers make connections between the two. New clinical examples have been added throughout the text.

Student Consult eBook version included with purchase. This enhanced eBook experience includes access -- on a variety of devices -- to the complete text, images, and references from the book.

FUNCTION 1

Chapter 1

INTRODUCTION TO BIOMOLECULES

Water Is the Solvent of Life

Ionizable Groups Are Characterized by Their pK Values

The Blood pH is Tightly Regulated

Acidosis and Alkalosis Are Common in Clinical Practice

Bonds Are Formed by Reactions between Functional Groups

Isomeric Forms Are Common in Biomolecules

Properties of Biomolecules Are Determined by Their Noncovalent

Interactions

Triglycerides Consist of Fatty Acids and Glycerol

Monosaccharides Are Polyalcohols with a Keto Group or an

Aldehyde Group

Monosaccharides Form Ring Structures

Complex Carbohydrates Are Formed by Glycosidic Bonds

Polypeptides Are Formed from Amino Acids

Summary

Chapter 2

INTRODUCTION TO PROTEIN STRUCTURE

Amino Acids Are Zwitterions
