Multiple Choice

Glucose tolerance factor (GTF) found in brewer's yeast contains which trace element?

Explanation:
Glucose tolerance factor is a small chromium-containing complex derived from brewer's yeast that enhances insulin action and promotes glucose uptake into cells. The trace element involved is chromium, usually in the trivalent form, bound in a complex with niacin and amino acids. This chromium component is what enables the full activity of the insulin signaling pathway, whereas cobalt (found in vitamin B12), copper, and manganese do not form part of GTF.
