This course is designed for students pursuing careers in pharmacy, medicine, and nutrition, providing a robust understanding of biological principles relevant to the healthcare field. Drawing on my extensive teaching experience across over 20 universities in Egypt and Saudi Arabia, this class will utilize effective online teaching techniques honed over six years of virtual instruction. Students will engage with interactive content, practical applications, and assessments that promote critical thinking and mastery of complex biological concepts. The curriculum will cover topics such as cellular biology, human physiology, biochemistry, and the molecular basis of health and disease. By the end of the course, students will have a solid foundation in carbohydrate, protein and lipid metabolism that supports their future studies and professional pursuits in the healthcare sector.
