Numéro d’image : 11521274
| Vitamin A. Molecular model of vitamin A,also called retinol (formula: C20H30O). The atoms are spherical and colour-coded: carbon (blue),oxygen (red) and hydrogen (white). Vitamin A is essential for normal growth,for bone and teeth formation,night vision and for protecting against infection. It is found in animal foods such as liver,fish- liver oil,eggs and dairy products. Carotene,from sources such as green vegetables and fruits,is converted into vitamin A in the liver. Deficiency leads to night-blindness,dry skin and eyes,and reduced resistance to infection. Prolonged excess intake can cause hypervitaminosis A,leading to nausea,hair loss and liver damage | |
