Ergosterol glucoside

Updated: 2026-09-15

Overview

Ergosterol glucoside is a sterol derivative primarily found in fungi and yeast. It plays a crucial role in the biosynthesis of vitamin D2 when exposed to UV light, making it significant in pharmaceutical and nutraceutical applications. The compound is known for its stability and bioactive properties, which are leveraged in research and industrial processes. As a naturally occurring molecule, ergosterol glucoside is often extracted from fungal sources or synthesized for specific uses. Its glucoside form enhances solubility in certain solvents, broadening its utility in formulations. The compound is also studied for its potential health benefits and role in fungal cell membranes.

Physical and Chemical Properties

Ergosterol glucoside is a white to off-white powder with a molecular weight of approximately 558.80 g/mol. It is soluble in organic solvents such as ethanol and methanol but insoluble in water, which influences its formulation and handling. The compound exhibits stability under standard storage conditions, though it should be protected from light and moisture to prevent degradation. Its molecular structure includes a sterol backbone conjugated with a glucose moiety, which contributes to its unique solubility and bioactive characteristics.

Main Applications

In the pharmaceutical industry, ergosterol glucoside is valued as a precursor for vitamin D2 production, which is essential for dietary supplements and fortified foods. Its bioactive properties also make it a candidate for research into antifungal agents and metabolic studies. Nutraceutical companies utilize this compound in formulations aimed at enhancing vitamin D intake. Additionally, it serves as a marker in fungal research, helping scientists understand cell membrane dynamics and sterol metabolism in microorganisms.

Safety and Storage

Ergosterol glucoside should be handled with standard laboratory precautions, including the use of gloves and eye protection to avoid irritation. It is not classified as highly hazardous, but proper ventilation is recommended when working with powdered forms. For long-term stability, the compound should be stored in a cool, dry environment, ideally in airtight containers with desiccants. Exposure to UV light or extreme temperatures should be minimized to preserve its integrity and efficacy.

B2B Procurement Guide

When sourcing ergosterol glucoside, buyers should prioritize suppliers who provide certificates of analysis (CoA) to verify purity and composition. Reputable manufacturers often adhere to Good Manufacturing Practices (GMP) for consistency and quality assurance. Pricing varies based on purity levels and order volumes, with bulk purchases typically offering cost advantages. Buyers should also consider logistics, such as shipping conditions and lead times, to ensure the product arrives in optimal condition.
