citrin
Học thuậtThân thiện
Definition
Noun: - A water-soluble vitamin complex, originally considered a single vitamin, that helps maintain the strength and resistance of capillary walls and cell membranes against permeation. It is now more commonly referred to as a component of the flavonoid group (bioflavonoids), which includes rutin and hesperidin.
Usage
- As a nutrient: Citrin is studied for its role in vascular health.
- Early research suggested that citrin could reduce capillary fragility.
- In historical/obsolete contexts: Referring to the former vitamin classification.
- The substance once called 'citrin' is now understood to be a mixture of flavonoids.
Advanced Usage
- "Citrin deficiency": A historical term for a condition theoretically involving capillary weakness, though not a recognized clinical deficiency syndrome in modern medicine.
- The concept of a citrin deficiency is largely obsolete.
Variants and Related Words
- Bioflavonoids (n): The modern collective term for the group of compounds, including rutin and quercetin, that citrin belongs to.
- Vitamin P (n): An outdated synonym for citrin or the bioflavonoid complex.
- Flavonoids (n): A broader class of plant compounds with various biological activities, which includes bioflavonoids.
Synonyms
- Bioflavonoids
- Vitamin P (obsolete)
- Flavonoid complex
Notes
- Important: 'Citrin' is primarily a historical term in nutrition and biochemistry. In contemporary scientific and medical contexts, the specific compounds within it (e.g., rutin, hesperidin) or the general term "bioflavonoids" are used instead. It is not officially recognized as a standalone vitamin in modern classifications.
Noun
- a vitamin that maintains the resistance of cell and capillary walls to permeation
