The molecular structure of the four fat-soluble vitamins and of cholesterol, the major intestinal sterol in man, are shown in Figure 1. In spite of the obvious dissimilarities that exist between these compounds they possess one common feature, namely, they are all nonpolar lipids with extremely low solubilities in aqueous media. Because of this, it is convenient to consider them together when e...

When cystic fibrosis (CF) was first recognized (Andersen, 1939), symptoms and signs of deficiency of vitamin A were common in infants with the condition. It was realized that pancreatic insufficiency from birth caused fat malabsorption and, therefore, malabsorption of the fat-soluble vitamins A, D, E and K. With the use of pancreatic enzyme replacement therapy and routine vitamin supplementatio...

CONTEXT Although vitamin deficiency is encountered infrequently in developed countries, inadequate intake of several vitamins is associated with chronic disease. OBJECTIVE To review the clinically important vitamins with regard to their biological effects, food sources, deficiency syndromes, potential for toxicity, and relationship to chronic disease. DATA SOURCES AND STUDY SELECTION We sea...

The prevalence of asthma and other atopic disorders continues to increase worldwide. Examination of the epidemiologic patterns has revealed that this rise has occurred primarily in western, industrialised countries and countries transitioning to this lifestyle. While many changes have occurred in human populations over the years, it has been hypothesised that some of the relevant changes that h...

The biofortification of staple crops with vitamins is an attractive strategy to increase the nutritional quality of human food, particularly in areas where the population subsists on a cereal-based diet. Unlike other approaches, biofortification is sustainable and does not require anything more than a standard food-distribution infrastructure. The health-promoting effects of vitamins depend on ...

With a view to study the formation of cross-links in BAPN treated rats by the simultaneous administration of certain vitamins, seven groups of weauling albino rats were raised for three weeks on basal dietalone or vitamin deficient basal diets with BAPN. One of the vitamins namely calcium pantothenate, vitamin E and vitamin B12 was supplemented along with BAPN. The analysis of skins showed that...

The effect of exclusion of individual water-soluble (thiamine, riboflavin, pyridoxine, cyanocobalamin, pantothenic acid, folic acid, niacin, biotin, choline, inositol, ascorbic acid) and fat-soluble vitamins (vit. A, D, K and E) in semi-purified diets on growth and survival of juvenile shrimp, P. monodon was studied in the laboratory for 8 weeks. Diets lacking riboflavin and vitamin K did not a...
