Analysis of fat-soluble vitamins from food matrix for nutrition labeling

This Application Note shows how to carry out qualitative and quantitative analysis of fat soluble vitamins from two different food matrixes. A robust reverse phase high performance liquid chromatographic (RP-HPLC) method for simultaneous determination of nine fat soluble vitamins was developed. Separation and quantification was achieved by an Agilent 1260 Infinity LC System using an Agilent Por...

Biosynthesis of Food Constituents: Vitamins. 1. Fat-Soluble Vitamins – a Review

Velíšek J., Cejpek K. (2007): Biosynthesis of food constituents: Vitamins. 1. Fat-soluble vitamins – a review. Czech J. Food Sci., 25: 1–16. This review article gives a survey of the generally accepted biosynthetic pathways that lead to fat-soluble vitamins (vitamin A, vitamin D, vitamin E, vitamin K, the corresponding provitamins, and the closely related ubiquinones and plastoquinones) in anim...

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...
