Regarding the first hypotheses, the research showed conclusively that the null hypothesis could be rejected. As such, the research hypothesis -- Sex would not have the same impact on the occurrence of Plasma Retinol (ng/ml) levels as it does on Plasma beta-carotene (ng/ml) levels – was accepted. Regarding the second hypothesis, the research showed that the null hypothesis could not be rejected and that research hypothesis that a correlation exists between the occurrence of Plasma Retinol (ng/ml) and Plasma beta-carotene (ng/ml) in the body could be rejected.
The first test that was carried out was a regression analysis. This regression analysis examined the correlation between sex and plasma Retinol (ng/ml) levels. As noted, this test demonstrated that there was a significant correlation between the two variables. The second test that was carried out was also a regression analysis. This test instead examined the connection between sex and plasma beta-carotene (ng/ml) in the body. This test demonstrated that there was not a significant connection between the variables. Finally, the third test that was carried out was an independent samples t-test. This test examined whether or not a correlation existed between plasma retinol (ng/ml) levels and Plasma beta-carotene (ng/ml). This research showed that a connection did not exist between these two ...Download file to see next pagesRead More

Micronutrien metabolism past and present (synthesis of vitamin A from beta carotene)
(Gropper P 333). Vitamin A can be derived from plant and animal sources. However, plant sources (cartenoids) must go through additional enzymatic activity in order to be converted to retinol. The focus of this paper will be to describe what was known of the conversion of -carotene to vitamin A in the 1920's and what is known today.
