A French-language scientific study of metabolic biochemistry with a focus on carbohydrate metabolism. The work addresses the biochemical principles and pathways involved in how living organisms transform, store, and use carbohydrates for energy and cellular function. Its scope suggests a structured academic treatment of intermediary metabolism, including enzymatic reactions, metabolic regulation, and the relationship between carbohydrate pathways and broader physiological processes. Intended for students and professionals in life sciences, health sciences, or biochemistry, the book serves as a specialized reference for understanding the chemical foundations of metabolism. It is best characterized as an educational scientific text rather than a general-interest overview, offering subject-specific coverage for readers seeking a systematic introduction to metabolic biochemistry.
