Component
Synthesis of membrane phospholipids
Synthesis of membrane phospholipids. Species, exposure and limitations are retained in each linked claim.
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.
Where it participates (unsigned role)
Acetate made a significantly larger carbon contribution to lipids than propionate, butyrate, glucose or glutamine in rat colonic epithelial cells, with butyrate and 3-hydroxybutyrate the other major contributors and glucose, glutamine and propionate making only minor contributions, and incorporation was significantly greater into phospholipids than into free fatty acids and triacylglycerides, suggesting the major role of this lipogenesis is membrane synthesis.
