Vitamins are divided into two groups: water-soluble (B-vitamins and C vitamin) and fat-soluble vitamins (A, D, E and K). Unlike water-soluble vitamins that need frequent supply, fat-soluble vitamins are stored in the liver and adipose tissues, and are eliminated much more slowly than water-soluble vitamins. In the blood stream, the fat-soluble vitamins are carried on proteins specialized for this task. Retinol (vitamin A) binds to retinol binding protein (RBP), vitamin D and its derivatives bind to vitamin D binding protein (DBP), whereas others like tocopherols (vitamin E) and phylloquinons/menaquinons (vitamin K) are carried by lipoproteins. The water soluble vitamins B and C flows freely dissolved in the water-phase of blood without the need of binding proteins.
In Vitas we have worked with vitamin analyses for 28 years and our people are experts on the topic. We master a broad range of techniques used for vitamin determination from a variety of sample types, including blood, serum, plasma, tissue, milk, urine, etc.
