Chemical classification of carbohydrates entering the colon

 Chemical classification of carbohydrates entering the colon


The chemical classification of carbohydrates entering the colon is as follows:

●Monosaccharides: all except for glucose, fructose, and galactose are partly or completely unabsorbed. Fructose in the absence of a source of glucose (mono-, di-, or polysaccharide) is partly unabsorbed.

 

●Sugar alcohols: all are partly or completely unabsorbed.

 

●Disaccharides: all except for maltose, sucrose, and lactose are unabsorbed. Lactose is completely or partly unabsorbed in individuals with low intestinal lactase activity.

 

●Oligosaccharides: all are unabsorbed except for maltodextins.

 

●Polysaccharides: all nonstarch polysaccharides are unabsorbed.

 

●Resistant starch.

Absorption, metabolism, and metabolic functions of pantothenic acid

  Absorption, metabolism, and metabolic functions of pantothenic acid   About 85% of dietary pantothenic acid is as CoA and phosphopantetheine. In the intestinal lumen these are hydrolyzed to pantetheine; intestinal mucosal cells have a high pantetheinase activity and rapidly hydro-lyze pantetheine to pantothenic acid. The intestinal absorption of pantothenic acid seems to be by simple diffusion and occurs at a constant rate throughout the length of the small intestine; bacterial synthesis may contribute to pantothenic acid nutrition.   The first step in pantothenic acid utilization is phos-phorylation. Pantothenate kinase is rate limiting, so that, unlike vitamins that are accumulated by meta-bolic trapping, there can be significant accumulation of free pantothenic acid in tissues. It is then used for synthesis of CoA and the prosthetic group of acyl carrier protein. Pantothenic acid arising from the turn-over of CoA and acyl carrier protein may be either reused or excre...

Metabolic functions of vitamin B6

  Metabolic functions of vitamin B 6 Pyridoxal phosphate is a coenzyme in three main areas of metabolism: ●        in a wide variety of reactions of amino acids, espe-cially transamination, in which it functions as the intermediate carrier of the amino group, and decar-boxylation to form amines   ●        as the cofactor of glycogen phosphorylase in muscle and liver, where it is the phosphate group that is catalytically important   ●        in the regulation of the action of steroid hormones. Pyridoxal phosphate acts to remove the hormone– receptor complex from DNA binding, and so ter-minate the action of the hormones. In vitamin B 6   deficiency there is increased sensitivity and respon-siveness of target tissues to low concentrations of steroid hormones, including estrogens, androgens, cortisol, and vitamin D.

Vitamin E Absorption and metabolism

  Absorption and metabolism Tocopherols and tocotrienols are absorbed unchanged from the small intestine, in micelles with other dietary lipids, and incorporated into chylomicrons. The major route of excretion is in the bile, largely as gluc-uronides and other conjugates. There are two mechanisms for tissue uptake of vitamin E. Lipoprotein lipase releases the vitamin by hydrolyzing the triacylglycerols in chylomicrons and VLDLs, while separately there is uptake of low-density lipoprotein (LDL)-bound vitamin E by means of LDL receptors. Retention within tissues depends on intra-cellular binding proteins, and it is likely that the dif-ferences in biological activity of the vitamers are due to differences in the affinity of these proteins for the different vitamers.
