Description

Cellobiose is a disaccharide sugar composed of two glucose molecules linked by a β(1→4) bond, serving as the fundamental repeating unit of cellulose. This high-purity biochemical is essential for research and industrial processes that require a defined and reliable carbohydrate substrate. It is a critical material for scientists and manufacturers in the biotechnology, pharmaceutical, and food science sectors seeking to study enzymatic activity, develop prebiotic formulations, or produce specialty chemicals.

Application

• Biochemical & Pharmaceutical Research: Used as a standard substrate for studying the activity of cellulase and β-glucosidase enzymes, crucial for biofuel and digestive supplement development.
• Prebiotic & Nutraceutical Development: Investigated for its potential as a selective prebiotic to promote beneficial gut microbiota growth in functional food and dietary supplement formulations.
• Food Science & Flavor Chemistry: Acts as a precursor for flavor compounds and a mild sweetener in specialized food products and sensory analysis.
• Microbiology & Fermentation: Serves as a defined carbon source in microbial culture media for the production of organic acids, enzymes, and other fermentation products.
• Cosmetic & Personal Care: Utilized in advanced skincare formulations for its potential moisturizing and skin-conditioning properties.
• Chemical Synthesis: Employed as a chiral starting material or intermediate in the synthesis of complex carbohydrates, glycoconjugates, and other specialty chemicals.

Quality Control

Our Cellobiose is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, optical rotation, and impurity profiles. We support compliance with relevant industry standards for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
