Intestinal absorption of vitamins
Current Opinion in Gastroenterology, 1999This article provides an overview of advances in understanding the cellular and molecular mechanisms and regulation of intestinal absorption processes of vitamins. The vitamins covered are the water-soluble vitamins folic acid, cobalamin (vitamin B12), biotin, pantothenic acid, and thiamine (vitamin B1) and the lipid-soluble vitamin A.

Intestinal absorption of vitamin D: from the meal to the enterocyte.
Food & Function, 2015Vitamin D plays key roles in bone, infectious, inflammatory and metabolic diseases. As most people get inadequate sun exposure for sufficient vitamin D status, they need adequate intake of dietary vitamin D.

The intestinal absorption of folates
The American Journal of Clinical Nutrition, 1979Dietary folates, existing primarily in the form of pteorylpolyglutamates, are absorbed in the jejunum by a process involving hydrolysis and subsequent intestinal transport of pterolymonoglutamyl folate. Current evidence indicates that one (or more) intestinal mucsoal enzyme(s), termed folate conjugase, is required for the hydrolysis of ...

Pharmacogenetics of Intestinal Absorption
Current Drug Delivery, 2008The small intestine is the primary site of absorption for many drugs administered orally and so is the target tissue for pharmacotherapeutic strategies to control the oral absorption of drugs. Drug transporters, including the ATP-binding cassette (ABC) superfamily and the solute carrier (SLC) superfamily, have been considered to play a physiological ...

Intestinal iron absorption is a critical process for maintaining body iron levels within the optimal physiological range. Iron in the diet is found in a wide variety of forms, but the absorption of non-heme iron is best understood. Most of this iron is moved across the enterocyte brush border membrane by the iron transporter divalent metal-ion ...

INTESTINAL ABSORPTION OF SUCROSE
Acta Medica Scandinavica, 1972Abstract: Sucrose in synthetized in the green leaves of plants. With increasing economical status the sucrose from sugar cane and beets, like fat, supplies an increasing fraction of our food. Sucrose is easily metabolized and utilized. Too high consumption is, however, not desirable from nutritional point of view, since this highly refined product ...

Intestinal Absorption of Aluminum
1992The intestinal absorption of aluminium can contribute significantly to systemic exposure to this element. Aluminium can be absorbed not only from oral pharmaceuticals but also from solid food and drinking water. The absorption process is not restricted to patients with kidney disorders; other groups of patients and healthy subjects are not excluded ...

Intestinal Absorption of Calcium
Archives of Internal Medicine, 1972Although the intestinal sites of calcium absorption were fairly well localized in the past, those mechanisms which conditioned the absorptive process have been incompletely understood. Recent advances in transport physiology and vitamin D and protein chemistry have added a new dimension to prevailing concepts of Ca transport across the intestinal ...

Delayed Intestinal Absorption of Levothyroxine
Thyroid, 1995We report four female patients with nodular goiter (in two of the four due to Hashimoto's thyroiditis) and one male patient with frank hypothyroidism due to Hashimoto's thyroiditis in whom TSH-suppressive or replacement L-T4 therapy failed to suppress or, respectively, normalize serum TSH.

The last 15 years has seen tremendous advances made in our understanding, at the molecular level, of the proteins involved in iron transport and regulation of iron metabolism with the major players involved in intestinal non-heme iron transport now identified. This achievement comes after several decades had seen little progress in this area and it was
