GENERAL HISTOLOGY

Detailed explanation-1: -Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across.

Detailed explanation-2: -During digestion, starches and sugars are broken down both mechanically (e.g. through chewing) and chemically (e.g. by enzymes) into the single units glucose, fructose, and/or galactose, which are absorbed into the blood stream and transported for use as energy throughout the body.

Detailed explanation-3: -Fiber is a type of carbohydrate that the body can’t digest. Though most carbohydrates are broken down into sugar molecules called glucose, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested.

Detailed explanation-4: -Monosaccharides such as glucose, fructose, and galactose. Amino acids from the breakdown of proteins. Nitrogenous bases from the breakdown of nucleotides. Glycerol and fatty acids, which are the products of lipids are absorbed by the lacteal inside the villi. More items
