Creative Proteomics is a pioneer in metabolic analysis service and provides reliable, professional and cost-effective retinol metabolism analysis service in animal. We leverage our rich experience, professional expertise, and advanced technologies to speed up your scientific purposes of retinol metabolism analysis in animal.

Overview

Retinol (also known as vitamin A1) is a vitamin in the vitamin A family. In many organs of animals, retinol is located at a metabolic crossroads in which it undergoes several biochemical reactions. Dietary intake of retinol is through liver parenchymal cells during chylomicron metabolism. But circulating retinol, mostly binding to retinol-binding protein (RBP), can enter and leave the liver in the process known as retinol recycling. Once taken up, retinol may be esterified via retinol acyltransferase and majorly stored as retinyl esters in stellate cells. Retinol may be metabolized to more polar forms through oxidation on its β-ionone ring and conjugation to form the water-soluble retinoyl glucuronides. Retinol at normal doses is well tolerated. High doses may result in an enlarged liver, dry skin or hypervitaminosis A. On the other hand, retinol deficiency causes various human diseases like night blindness and cancer. Therefore, understanding retinol metabolism is vital for animal's health. Scientists at Creative Proteomics take advantage of highly quantitative methods with high-performance liquid chromatography (HPLC) for the determination of retinol metabolism related metabolites levels in various samples. Furthermore, we provide reliable, rapid and cost-effective retinol metabolism related service to speed up your research aims ranging from diseases diagnosis to gaining new insights in disease mechanism or treatment.
