Carbohydrates and sugars
Carbohydrates are consumed in the daily diet as a mixture of polysaccharides, disaccharides, and monosaccharides. Digestion of carbohydrates begins in the mouth with salivary amylase and ends in the small intestine with brush border enzymes. Monosaccharides are absorbed into the bloodstream and taken to the liver via the hepatic portal vein.
