Tag: L arabinose

According to a 2025 study on individuals with impaired fasting glucose, a single dose of L-arabinose significantly reduced blood glucose peaks by 14% and insulin peaks by 30%. This naturally occurring sugar, often sourced from plant biomass like corn cobs, is gaining attention for its ability to block sugar absorption in the small intestine. These unique properties provide numerous benefits for metabolic health and weight management.

As an aldopentose, arabinose is a five-carbon monosaccharide that is a fundamental component of various plant cell wall polysaccharides. This simple sugar is important for its dual function: in human nutrition, L-arabinose acts as a potent inhibitor of the enzyme sucrase, while in bacterial systems, it is a key regulatory molecule controlling gene expression.
