Vitamin A Pdf Vitamin A Vitamin a is a fat soluble vitamin, a category that also includes vitamins d, e and k. the vitamin encompasses several chemically related naturally occurring compounds or metabolites, i.e., vitamers, that all contain a β ionone ring. [4]. Vitamin a is a fat soluble life essential group of compounds both of animal and vegetal origin characterized by an unsaturated isoprenoid chain structure. all vitamin a forms share a similar structure and the same physiological functions in an organism.
Vitamin A Pdf The two main forms of vitamin a in the human diet are preformed vitamin a (retinol, retinyl esters), and provitamin a carotenoids such as alpha carotene and beta carotene that are converted to retinol. This review aims to evaluate the importance of vitamin a in human health and understand the underlying mechanisms that lead to the development of diseases. this study analyses the unique properties of vitamin a and its food sources. Derived from various sources, vitamin a can be found in foods of animal origin as preformed vitamin a, while plants provide provitamin a carotenoids, such as β carotene. therefore, vitamin a is not just a singular compound. it encompasses a group of related compounds known as retinoids. Vitamin a is a fat soluble vitamin. its different forms are often called "retinoids." they include retinol, retinal, retinoic acid, and retinyl ester. vitamin a is needed for the proper.

Vitamin a is not present in plants, but many vegetables and fruits contain one or more of a class of pigments that can be converted to vitamin a in the body; of these pigments, beta carotene (provitamin a) is an excellent source of vitamin activity. Since vitamin a is fat soluble, it is packaged into chylomicrons in the small intestine, and transported to the liver. the liver stores and exports vitamin a as needed; it is released into the blood bound to a retinol binding protein, which transports it to cells. Precursors to vitamin a, also known as provitamin a, are found in plant based foods such as fruits and vegetables. the most common type of provitamin a is beta carotene. Vitamin a is the name of a group of fat soluble retinoids, primarily retinol and retinyl esters [1, 2]. vitamin a is involved in immune function, cellular communication, growth and development, and male and female reproduction [1 3].
