Polyglucans and beta-glucans are commonly derived from which source?

Yeast cells
Animal cells
Plant material
Mineral extracts

The correct answer is: Yeast cells

Polyglucans and beta-glucans are polysaccharides that are primarily derived from yeast cells, particularly from the cell walls of certain yeast species. These compounds have gained prominence in the skincare and cosmetic industry due to their beneficial properties, including their ability to enhance skin hydration, improve skin barrier function, and boost the skin's immune response. Yeast-derived beta-glucans are known to possess soothing and anti-inflammatory effects, making them valuable ingredients in products designed for sensitive or irritated skin. The uniqueness of these polysaccharides lies in their molecular structure, which can interact favorably with skin cells, offering protective and reparative effects. Other sources like animal cells, plant materials, or mineral extracts do not produce polyglucans and beta-glucans in the same way that yeast does, limiting their use in this context. Therefore, yeast cells are recognized as the primary source of these beneficial compounds in skincare formulations.
