phlozirin

Definition

1. Noun:
   • Chemical compound: "phlozirin" (also spelled phlorizin) is a bitter, crystalline glycoside found in the bark and root bark of apple, pear, cherry, and other fruit trees. It inhibits the reabsorption of glucose in the kidneys, causing glycosuria (excretion of sugar in urine), and is used in medical research to study diabetes and kidney function.

Usage Examples

• Noun:
  • Phlozirin is often extracted from apple tree roots for experimental purposes. (The compound is obtained from the roots of apple trees.)
  • Researchers administered phlozirin to laboratory animals to induce temporary diabetes. (The compound was used to cause a diabetic state in test subjects.)

Advanced Usage

• "phlozirin-induced glycosuria": a condition of glucose in the urine caused by the administration of phlozirin.

  • The study observed phlozirin-induced glycosuria in rats after a single dose. (The rats developed sugar in their urine due to the compound.)

• "phlozirin sensitivity": the responsiveness of kidney cells to the compound's inhibitory effect on glucose transport.

  • Differences in phlozirin sensitivity were noted between species. (Some species were more affected by the compound than others.)

Variants and Related Words

• Phlorizin (n): an alternative spelling of phlozirin.

  • Phlorizin is the more common spelling in modern chemical literature. (The term is often written with an 'r' after the 'l'.)

• Phloretin (n): a related compound formed when phlozirin is broken down by enzymes.

  • Phloretin is a hydrolysis product of phlozirin. (Phloretin is produced when phlozirin reacts with water.)
