The Role of Vitamin-A, Vitamin-Beta-Carotene, Vitamin-E and Vitamin-C in Cancer Cell BiologyLupulescu, ALupulescu A (1994) The role of vitamin-A, vitamin-beta-carotene, vitamin-E and vitamin-C in cancer cell biology. Int J Vitam Nutr Res 64: 3-14....
The cleavage of β-carotene yields two molecules of vitamin A. To create the first generation of golden rice, gene delivery was used to introduce an entire biosynthetic pathway into the plant cells using promoters that are specific to the endosperm (Figure 18.10). The endosperm was chosen ...
1.Beta-carotene is an antioxidant and therefore may offer some protection against certain cancers and other diseases. 2.Beta-carotene is a naturally occurring substance present in green and yellow fruits and vegetables. 3.In the body, beta-carotene is converted...
Beta-carotene is the molecule that gives carrots their orange colour.It is part of a family of chemicals called the carotenoids, which are found in many fruit and vegetables, as well as some animal products such as egg yolks. Biologically, beta-...
Beta-carotene powder is dark red crystalline powder. B-eta-carotene insoluble in water, slightly soluble in ethanol and ether, soluble in chloroform, benzene and oil.Beta-carotene's melting point is 176 ~ 180 C. Beta-carotene can be transformed into vitamin A ...

A process for obtaining beta -carotene. The present invention relates to a new process for the production of beta -carotene from submerged cultures of mucor fungi such as Blakeslea, Choanephora or Phycomyces by means of addition to the culture medium of lecithin in conjunction with pH control...

In zebrafish, targeted gene knockdown of 尾,尾-carotene-15,15鈥 -oxygenase (bcox), the key enzyme for vitaminA formation, provokes a loss of retinoid signalling during early eye development that results in microphthalmia at larval stages. Using this model, we analysed the consequences of this ...
