Component
Lysine metabolic availability
Independent cellular process record; interpretation is limited by each linked claim and its study context.
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
The tested whole-wheat bread supplied lysine with an estimated 90% metabolic availability, while low lysine concentration still limited its protein quality.
Experimental context and source evidence
- experimental_model
- Randomized intake-order repeated-measures experiment in five young men
- exposure
- Lysine supplied by the tested whole-wheat bread; bread is a food matrix recorded in context, not a chemical-species entity.
- limitations
- Specific bread and small sample; metabolic availability is method-dependent and does not establish adequacy of all wheat-based diets.
- organism
- Homo sapiens
- plain_language
- A food can deliver most of its lysine efficiently yet contain too little lysine relative to other amino acids.
