Uses

  • L-Arabinose is a crucial component in biochemical investigations, specifically in the fields of microbiology and biomedicine.
  • It is used as a selection marker in molecular biology experiments, particularly in the study of gene expression in certain bacterial systems.
  • It is sometimes also included in bacterial culture media as a carbon source.
  • It is also effective for use in the bioproduction of L-ribose and as a substrate for pentose sugar isomerase identification, differentiation, and characterization.

FAQs

Q. Does L-Arabinose have an aldehyde or ketone group ?

L-Arabinose is a monosaccharide with aldehyde functional group.

Q. Is L-Arabinose an inhibitor?

L-arabinose selectively inhibits the intestinal enzyme sucrase, which is responsible for the breakdown of sucrose into glucose and fructose in the small intestine, in an uncompetitive manner and thus suppresses the glycemic response after sucrose ingestion in animals.
