Nutrients and their absorption center
- Carbohydrate: Simple sugar are absorbed into the small intestine and into the portal blood system and then to the liver in the form of glucose.
- Fat: Is absorbed through intestinal membrane in the form of fatty acids and monoglycerides. A few diglycerides, and triglycerides are also absorbed. The synthesis of triglycerides takes place in the ER of intestinal wall. Here, Fatty acids are simultaneously absorbed.
- Protein: Absorption takes place in small intestine. Amino acids pass into portal blood and then to the liver.
- Minerals: Vitamin D promote the absorption of both Ca and P.
- Vitamins: Are readily absorbed from the digestive tract into the small intestine.
