Biochemistry is the science of life.Most science courses have biochemistry incorporated in their course synopsis. However biochemistry focuses on different aspects of the different areas of specialization. The medical student focuses on the study of chemical substances and the vital processes occuring in living organisms.The student of agriculture is more concerned with the structure function and metabolism of the major nutrient molecules(carbohydrates,lipids and proteins)enzme reactions and importance of vitamins to growth and development.The role of photosynthesis in the production energy rich nutrient molecules is also of prime importance for students of agriculture.The sudent of agriculture focuses on the catabolism and anabolism of nutrient molecules as it concerns the biosynthesis of celluar components and the building upof cellular structures.This book is written for students studying agricultural sciences who would need a knowledge of basic biochemistry especially in their different areas of research and development.
