This textbook of biochemistry has been completely revised and expanded for its second edition. Biotechnologists and bioprocess engineers will find precise information on modern issues in the fascinating and complex field of technical biochemistry, where technology and biology need not be a contradiction. The authors have attempted to write a textbook for students of bioengineering from the students' perspective. Unlike well-known and well-established textbooks in biology, biochemistry, and biotechnology, this book presents biological concepts and links them with technical and engineering problems. The aim of this textbook is to shed light on biochemical principles in natural product biosynthesis and explain their biotechnological and bioprocess engineering production pathways. Content: Application of biochemistry in medicine, pharmacy, and engineering Photosynthesis - The chemistry of light Carbohydrate metabolism - Sugars as energy carriers Amino acids and peptides - Proteins as biocatalysts Carbohydrates, lipids, and proteins - Building blocks for technical and pharmaceutical substances Important biosyntheses of primary and secondary metabolism Natural product biosynthesis - Biology and chemistry of secondary metabolites Target Audience: Students of bioprocess engineering, biotechnology, pharmacy, chemistry Biologists, biotechnologists, process engineers, pharmacists, chemists with a focus on biotechnology
