What is the difference between alpha carotene and beta carotene?
Alpha carotene and beta carotene are both forms of carotenoids, which are plant pigments converted into vitamin A in the body. The main difference is in their molecular structure, with alpha carotene having one more double bond than beta carotene. Both are powerful antioxidants, but research suggests that beta carotene may be more potent and have higher levels in certain foods like carrots and sweet potatoes.
What research has been done on vitamin A?

Can Beta-carotene can be converted to active vitamin A on a one to one ratio?
No. No ref, but 2:1 ratio is bandied about.
What one food source of Vitamin A might pose a toxicity issue?
Food sources don't pose Vitamin A toxicity issues. While too much vitamin A from supplements can be dangerous, beta-carotene (the natural form found in foods) doesn't pose such a risk. Additionally, the relative amount of Vitamin A found in foods as compared to a concentrated vitamin tablet is much, much less.

How do you separate lycopene and beta-carotene?
A good technique is HPLC (liquid chromatography). You'll find references to this approach for the two plant pigments you're interested in. Possibly also, there are patents on this. The procedures outlined in patents are likely to be more efficient, but you can't use these commercially without permission of the patent holders.
How have scientist improved rice one of the world most important food sources?
Rice is a staple for more than half the world's population. Yet it contains very little beta carotene, a necessary protein.
