phytochemical
Noun: A naturally occurring chemical compound found in plants. These substances are biologically active, meaning they can have effects on living organisms, but they are not considered essential nutrients (like vitamins or minerals) for human health.
The term is used primarily in the fields of nutrition, biochemistry, and medicine to describe plant-derived compounds studied for their potential health effects. * Scientists are researching the phytochemical resveratrol, found in grape skins. * Many fruits and vegetables contain beneficial phytochemicals. * The biological activity of a phytochemical may help protect cells from damage.
- As a modifier: The term is frequently used as an adjective in compound nouns like "phytochemical analysis" or "phytochemical profile," referring to the study or composition of these plant chemicals.
- In contrast to nutrients: A key distinction is that phytochemicals are "not nutritive." They are not classified as essential nutrients required to prevent deficiency diseases, but rather as compounds that may provide other health benefits.
- Phytonutrient (noun): A near-synonym often used in nutritional contexts, though it can sometimes blur the line with "nutritive" compounds. "Phytochemical" is the more precise scientific term.
- Secondary metabolite (noun): A broader biochemical term for compounds produced by plants (or other organisms) that are not essential for basic growth, but often serve defensive or signaling roles. Many phytochemicals are plant secondary metabolites.
- Plant chemical
- Bioactive plant compound
The definition is specific and does not have widely divergent meanings. Its core meaning is always a biologically active, non-nutritive chemical from plants. It should not be confused with: * Pharmaceutical: A medical drug, which may be synthesized or derived from any source. * Nutrient: An essential substance like a vitamin, mineral, carbohydrate, protein, or fat.
