Absorption of fat-soluble vitamins and sterols

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...

Fat-soluble vitamins in cystic fibrosis.

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...

Hypertension and the Fat-Soluble Vitamins A, D and E

Hypertension affects populations globally and is thus a public health and socio-economic problem. Macronutrient and micronutrient deficiencies are common in the general population, and may be even more prevalent in hypertensive patients. This study aimed to determine a possible association between hypertension and intake of fat-soluble vitamins A, D and E. Participants were from the cross-secti...
