Vitamin A

Vitamin A

Vitamin A adalah kumpulan sebatian organik pemakanan tak tepu, termasuk retinol, retina, asid retinoik, dan beberapa provitamin A karotenoid, di antaranya beta-karoten adalah yang paling penting. Vitamin A mempunyai pelbagai fungsi: penting untuk pertumbuhan dan pembangunan, untuk mengekalkan sistem imun dan penglihatan yang baik. Vitamin A diperlukan oleh retina mata dalam bentuk retina, yang menggabungkan opsin protein untuk membentuk rhodopsin, molekul penyerap cahaya yang diperlukan untuk kedua-dua cahaya rendah dan penglihatan warna. Vitamin A juga berfungsi dalam peranan yang sangat berbeza seperti asid retinoik, yang merupakan faktor pertumbuhan hormon penting untuk epitelium dan sel-sel lain. Dalam makanan haiwan, bentuk utama vitamin A adalah ester, terutama retinyl palmitate, yang ditukar kepada retinol dalam usus kecil. Bentuk retinol berfungsi sebagai bentuk penyimpanan vitamin, dan boleh ditukar kepada dan dari bentuk aldehid aktif, retina. Semua bentuk vitamin A mempunyai cincin beta-ion yang mana rantai isoprenoid dilampirkan, dipanggil kumpulan retinil. Kedua-dua ciri struktur adalah penting untuk aktiviti vitamin.

Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the most important. Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision. Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light and color vision. Vitamin A also functions in a very different role as retinoic acid, which is an important hormone-like growth factor for epithelial and other cells. In foods of animal origin, the major form of vitamin A is an ester, primarily retinyl palmitate, which is converted to retinol in the small intestine. The retinol form functions as a storage form of the vitamin, and can be converted to and from its visually active aldehyde form, retinal. All forms of vitamin A have a beta-ionone ring to which an isoprenoid chain is attached, called a retinyl group. Both structural features are essential for vitamin activity.
