NUTR 482 Lecture Notes - Lecture 5: Transamination, Gluconeogenesis, Vitamin A Deficiency
Document Summary
Most fat-soluble and water-soluble vitamins are absorbed in the small intestine, aside from vitamin k and biotin which are also absorbed in the large intestine. Fat-soluble vitamins require bile into order to form micelles for absorption: akers, j. l12_vit. min_f16s [powerpoint]. Factors that can have an impact on the processes of absorption, transportation and storage for minerals include other substances in the body such as high amounts of proteins, carbohydrates or fats or the presence of other vitamins/minerals. Alternatively, the presence of other certain vitamins and minerals may either increase or decrease absorption rates of some minerals. For example, the absorption of phosphorous is enhanced by calcitriol and vitamin d but inhibited by phytic acid or excessive magnesium, aluminum or. Another factor that may impact these processes is the metabolic state of the body. For example, calcium absorption is high during times of increased needs (i. e. , growth pregnancy, childhood)
