Biochemical Engineering : Level: 3 Year Bachelor's Degree (LMD) in Biotechnology and Health

Abstract

Bioengineering is an interdisciplinary field that integrates cell and molecular biology, biochemistry, and chemical engineering to understand, analyze, and exploit complex biological systems for industrial, medical, and biotechnological purposes. This discipline extends beyond the theoretical study of biological phenomena to encompass the design and development of processes involving biological materials within cells, as well as the use of living organisms or their enzymatic systems. In this context, a deep understanding of cellular organization at the molecular level has become essential, particularly in light of rapid advances in molecular biology, genetic engineering, and modern biotechnological technologies. The cell is no longer regarded as a simple structural entity, but rather as a highly complex dynamic system composed of interconnected networks of biochemical reactions, signaling pathways, and precisely regulated structural components that ensure the continuity of life. The significance of bioengineering lies in its capacity to interpret and model these biological systems into exploitable bioprocesses, including the production of therapeutic proteins, vaccines, industrial enzymes, and high-value bioproducts. It also plays a central role in optimizing biological processes in bioreactors and in investigating cellular behavior under controlled conditions in order to guide cells toward specific production outcomes. This course is structured around two main axes that form the foundation for understanding cellular organization within this discipline. The first axis focuses on membrane topology and dynamics, addressing the structural organization of biological membranes, the distribution and interaction of their components, their physicochemical properties, and their fundamental roles in transport, intercellular communication, and signal transduction. The second axis explores the molecular basis of cellular homeostasis, describing how internal cellular equilibrium is maintained through highly coordinated networks of receptors, ligands, signaling proteins, and second messengers that regulate cellular responses in an integrated manner. Furthermore, this field is crucial for understanding complex pathological mechanisms, as many diseases such as cancer, metabolic disorders, and genetic diseases are directly associated with alterations in molecular regulation and cellular signaling pathways. Consequently, the study of these concepts not only advances fundamental scientific knowledge but also provides a foundation for the development of innovative therapeutic strategies and biomedical applications.
