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...

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 Contents in Atlantic Mackerel from the North

The main purpose of this study in order to estimate fat soluble vitamins contents Mackerel fillets from the northeastern coast of Tunisia. Retinol, α-tocophérol and cholecalciferol were analyzed using HPLC system. The experimental procedure used for extraction consisted on saponification, normal phase separation with UV and fluorescence detection for tocopherol and retinol. While cholecalcifero...
