D-ribose

D-Ribose (CAS 50-69-1) is a naturally occurring pentose sugar used across food, pharmaceutical, and biotechnology sectors. As a FEMA 3793-listed ingredient, it is recognized as a flavoring substance and functional nutrient. In formulation and manufacturing, it acts primarily as a biochemical substrate, humectant, and energy-support ingredient. In food and nutraceutical products, it is incorporated into sports nutrition supplements and energy drinks.

Functional foods targeting cellular energy replenishment frequently utilize this sugar. Pharmaceutical and healthcare formulators use it as a precursor in the biosynthesis of nucleotides, coenzymes, and active pharmaceutical ingredients. This includes the production of various antiviral compounds. Biotechnology and life sciences manufacturers rely on it as a carbon source and substrate in fermentation media, cell culture systems, and enzymatic assay reagents.

In personal care formulations, it functions as a humectant and Maillard reaction participant. This contributes to skin-conditioning effects in select cosmetic applications where cellular energy support is a primary goal. The material is supplied as a white crystalline powder. Food-grade and USP-grade specifications are the most commonly traded forms, with food-grade material frequently meeting FCC standards for use in dietary supplements.

Bulk quantities are available for industrial procurement across various sectors. Pharmaceutical-grade material is subject to additional purity and documentation requirements to ensure compliance with global manufacturing regulations.
