The Provitamin D in Clams [PDF]

Nature, 1949
THE communication on the "Conversion of Cholesterol to Provitamin D 3 in vivo" by Mary Scott, J. Glover and R. A. Morton in Nature of April 2, p. 530, prompts us to publish our results for the provitamin in clams. In order to obtain experimental evidence for the hypothesis that the provitamin D is essentially of endogenous origin, we investigated ...

Performance of testers with contrasting provitamin A content to evaluate provitamin A maize for resistance to Aspergillus flavus infection and aflatoxin production

Frontiers in Plant Science, 2023
In sub-Saharan Africa (SSA), millions of people depend on maize as a primary staple. However, maize consumers in SSA may be exposed to malnutrition due to vitamin A deficiency (VAD) and unsafe aflatoxin levels, which can lead to serious economic and ...
