Nutritional Aspects of Digestive Systems (ALS 5104 / HNFE 5104)
Catalog Description
Principles of gastrointestinal tract structure, motility, and digestive functions with emphasis on neuroendocrine and metabolic regulation of absorption and transport of carbohydrates, lipids, amino acids, minerals, and vitamins during the life cycle of food animals and humans.
Lecture Topic
