The Intestinal Villi Explained -- Absorption Improving nutrient absorption mechanisms survive, your nnutrient must have a system for transforming food and drink Improving nutrient absorption mechanisms nutrients that it can absorb and use. Digestion begins when you see, smell, feel, or absorpyion foods. The absorptlon and nervous systems signal the gastrointestinal tract that food is on the way. Muscles flex and digestive secretions flow. Cooperating organs including the mouth, esophagus, stomach, small and large intestines, pancreas, liver, and gall bladder orchestrate digestion. To get the nourishment you need, nutrients must successfully traverse the gastrointestinal tract GIT. The GIT is a long, muscular tube that extends from the mouth to the anus.

Am J Clin Nutr S- S, Zinc deficiency may be caused by insufficient zinc intake, factors inhibiting zinc absorption such as phytate and polyphosphate, consumption of medicines that inhibit zinc absorption or increase zinc excretion, or congenital zinc deficiency.

Congenital zinc deficiency is known as acrodermatitis enteropathica AE [20] Kury S , Dreno B , Bezieau S , Giraudet S , Kharfi M , Kamoun R , Moisan JP : Identification of SLC39A4, a gene involved in acrodermatitis enteropathica. Nat Genet , Am J Hum Genet 73, J Biol Chem , Int J Endocrinol , Zinc deficiency may increase the risk of undernutrition due to taste disorders and anorexia, and delay the healing of bedsores; therefore, prevention of zinc deficiency is important.

The absorption rate of zinc in the gastrointestinal tract varies depending on the amount consumed. Am J Clin Nutr , Plant foods are one of the major sources of zinc.

However, plant foods, especially the starch layer and germ of cereals, endosperm, and cotyledons of legume seeds also contain a large amount of phytic acid myo-inositol hexaphosphate , which inhibits zinc absorption; thus, the bioavailability of their zinc may not be high [30] Schlemmer U , Frølich W , Prieto RM , Grases F : Phytate in foods and significance for humans: food sources, intake, processing, bioavailability, protective role and analysis.

Mol Nutr Food Res S S, Nutrients , Nutr Rev , Nature 95, Several factors inhibit the absorption of zinc in food additives. Phytic acid, as mentioned above, is used to prevent discoloration, oxidation, and pH adjustment of foods via its metal-chelating effect.

Food and Drug Administration. Zinc ingested from food is primarily absorbed in the duodenum and jejunum, bound to albumin and α2-macroglobulin in the portal vein, adsorbed into the liver, and subsequently distributed to peripheral tissues.

Zinc that is not absorbed into the gastrointestinal tract or contained in gastrointestinal secretions and sloughing mucosal cells is excreted in the feces [1] Kambe T , Tsuji T , Hashimoto A , Itsumura N : The physiological, biochemical, and molecular roles of zinc transporters in zinc homeostasis and metabolism.

Zinc homeostasis is regulated by several proteins, including zinc transporters and metallothioneins. Zinc transporters include the ZRT, IRT-like protein ZIP and Zn transporter ZNT families. Fourteen members of the ZIP family and 10 members of the ZNT family have been identified in humans; however, ZNT9 is thought to have no zinc transport function [1] Kambe T , Tsuji T , Hashimoto A , Itsumura N : The physiological, biochemical, and molecular roles of zinc transporters in zinc homeostasis and metabolism.

The zinc transporter ZIP4 is expressed on the apical membrane of intestinal epithelial cells, and ZNT1 is expressed on the basolateral membrane of intestinal epithelial cells; both play a critical role in intestinal zinc absorption. ZIP4 transports zinc from the lumen into enterocytes, and ZNT1 exports zinc into the portal blood.

These transporters regulate the absorption of dietary zinc in the gastrointestinal tract Fig. Dietary zinc absorption mechanisms.

Dietary zinc is primarily absorbed by the duodenum and jejunum. Divalent zinc ions released from food are taken up intracellularly via ZIP4, which accumulates on the luminal side of intestinal epithelial cells.

Zinc is transported into the blood via ZNT1, which is present on the basolateral membrane. Zinc in plasma is bound to albumin and α2-macroglobulin and delivered to the whole body.

Zinc that is not absorbed by the gastrointestinal tract or contained in detached intestinal cells, pancreatic juice, or bile, is excreted in feces. Zinc is also excreted in urine and sweat. Hum Mutat , PLoS Genet 8: e, Biol Chem , Am J Physiol Regul Integr Comp Physiol R R, Regulation of ZIP4 and ZNT1 expression according to zinc levels.

ZIP4 expression is regulated by dietary zinc in a post-transcriptional, and post-translational manner. Under conditions of zinc deficiency, ZIP4 accumulates on the apical membrane through mRNA stabilization and inhibition of protein degradation.

When there is sufficient zinc, ZIP4 is rapidly endocytosed and undergoes ubiquitin-mediated degradation. In contrast, ZNT1 undergoes endocytosis and intracellular degradation during zinc deficiency, whereas it accumulates on the basolateral membrane under zinc-sufficient conditions, regulated by metal response element binding transcription factor 1 MTF MTF-1 senses cytoplasmic zinc concentration in enterocytes and regulates ZNT1 expression.

Biochem J , Cold Spring Harb Perspect Biol 5: a, ZNT1 is expressed in various tissues; in the intestinal tract, it is expressed in the basolateral membrane and is thought to function in the transport of zinc from the intestinal epithelial lining to the bloodstream [50] Wang X , Wu Y , Zhou B : Dietary zinc absorption is mediated by ZnT1 in Drosophila melanogaster.

FASEB J , In addition, ZIP5 and ZIP14 are expressed on the basolateral membrane of intestinal epithelial cells and are thought to transport zinc from the blood to intestinal epithelial cells [41] Weaver BP , Dufner-Beattie J , Kambe T , Andrews GK : Novel zinc-responsive post-transcriptional mechanisms reciprocally regulate expression of the mouse Slc39a4 and Slc39a5 zinc transporters Zip4 and Zip5.

Am J Physiol Gastrointest Liver Physiol G G, Int J Vitam Nutr Res , Moreover, the systemic hormone hepcidin, which is produced in response to iron loading and regulates iron homeostasis, appears to attenuate ZNT1 expression and influence its export from small intestinal epithelial cells [56] Hennigar SR , McClung JP : Hepcidin attenuates zinc efflux in Caco-2 cells.

J Nutr — , As zinc exists as a divalent ion, its absorption mechanism in the gastrointestinal tract is different from that of iron and copper. Iron and copper ions present in food are reduced by their respective reductases before uptake into intestinal epithelial cells by their respective transporters, DMT1 and CTR1.

Therefore, the absorption of iron and copper is markedly affected by the activity of reductases [57] Hashimoto A , Kambe T : Mg, Zn and Cu transport proteins: a brief overview from physiological and molecular perspectives, J Nutr Sci Vitaminol S , Science , Based on the hypothesis that food factors that increase the expression of ZIP4 have a positive effect on zinc absorption, we established a screening method for dietary components that would enable an increase in ZIP4 expression and cellular zinc levels.

We examined more than food extracts, and found several soybean extracts were effective in promoting the expression of ZIP4 [59] Hashimoto A , Ohkura K , Takahashi M , Kizu K , Narita H , Enomoto S , Miyamae Y , Masuda S , Nagao M , Irie K , Ohigashi H , Andrews GK , Kambe T : Soybean extracts increase cell surface ZIP4 abundance and cellular zinc levels: a potential novel strategy to enhance zinc absorption by ZIP4 targeting.

Zinc is an essential trace jechanisms with various physiological functions; it is a structural, catalytic, and signaling component of proteins. Improving nutrient absorption mechanisms to its wide range of Improving nutrient absorption mechanisms, zinc deficiency causes Improving nutrient absorption mechanisms symptoms, such nurtient taste nutrjent, dermatitis, hair Understanding DEXA scan results, decreased appetite, abslrption disorders, and gonad dysfunction. Approximately 2—3 g of zinc is present in the adult human body. Systemic zinc homeostasis is regulated by the zinc transporters ZIP4 and ZNT1, which play major roles in regulating the absorption of food-derived zinc, primarily in the duodenum and jejunum. ZIP4 is expressed on the apical membrane of intestinal epithelial cells and allows divalent zinc ions to enter cells from the lumen. Zinc in enterocytes is subsequently transported by ZNT1 on the basolateral membrane into the portal vein, where it binds to albumin and α2-macroglobulin.
