Component
DHA phospholipid remodeling
Acyl turnover of DHA-containing phospholipids, distinguished from absolute DHA concentration.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
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 acts on it
Embryos from vitamin E-depleted zebrafish parents incorporated more water-18O label into LPC 22:6 and three DHA-containing phosphatidylcholines during 48–72 hours post-fertilization than vitamin E-sufficient controls, supporting increased acyl turnover.
