L-Arabinose is a five-carbon sugar (aldopentose) with an aldehyde group generally found in nature. Unlike most sugars, which occur mostly in their D-form, it is more abundant and a vital component of natural biopolymers like hemicellulose and pectin. It has been researched broadly, particularly for its role in the L-arabinose operon in E. coli, which is involved in the breakdown of arabinose. L-Arabinose gets its name from gum arabic, the substance from which it was first isolated.
CAS No.: 5328-37-0
Synonyms: Ara; Arabinopyranose; Arabinopyranoside; Arabinose; L-Ara; L-Arabinopyranose; L-Arabinopyranoside; L(+)-Arabinose.

L-Arabinose is a five-carbon sugar (aldopentose) commonly found in nature as a component of plant biopolymers like hemicellulose and pectin.
It is considered healthy as it can inhibit sugar absorption in the small intestine, potentially helping to regulate blood sugar levels.
Yes, L-Arabinose acts as an inhibitor of the sucrase enzyme, which breaks down sucrose into glucose and fructose in the small intestine.
It is used as a food additive, a selection marker in molecular biology, and a carbon source in bacterial culture media. It is also utilized in bioproduction and enzyme studies.
It helps in regulating blood sugar levels, supports weight management, and improves cholesterol levels. It also has potential anti-inflammatory benefits and may protect the blood-brain barrier.
