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
Chronically vitamin-C-restricted guinea pigs had a higher brain DHA percentage despite lower total brain vitamin C.
Experimental context and source evidence
- availability_state
- nutrient_deficiency Imported condition classification; unverified.
- cross_nutrient
- false
- experimental_model
- Thirty female guinea pig offspring, control/deficient/repleted diets, postnatal day 70
- exposure
- Prenatal/postnatal 100/100 mg vitamin C/kg diet versus 900/750 mg/kg controls; female offspring at day 70
- limitations
- A higher oxidized fraction does not establish higher absolute DHA concentration.
- nutrient_topic
- Vitamin C research collection; topical membership is not evidence of a direct dietary effect. · Vitamin C
- organism
- Cavia porcellus
- plain_language
- A larger fraction of the smaller brain vitamin C pool was oxidized.
