How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What it acts on
Delphinidin 3,5-diglucoside showed no detected yeast alpha-glucosidase inhibition in the tested range.

**Enzyme identity changes the digestive-enzyme claim.** A purified-compound assay used yeast α-glucosidase and a synthetic substrate, not human sucrase-isomaltase. Delphinidin aglycone inhibited with an IC50 near 4.11 µM; cyanidin was about 17.01 µM. Delphinidin-3-glucoside was much weaker, around 364 µM, and its 3,5-diglucoside showed no detected inhibition in the tested range. These values establish structure-dependent assay behavior. They cannot be imported as human intestinal IC50 values or a clinical comparison with acarbose. Docking does not repair that species/substrate gap.
