hemicellulose

HEM-ee-sell-yuh-lohss

Definition

A type of plant-derived polysaccharide that forms part of the cell wall structure along with cellulose and lignin, serving as a primary feedstock material for producing biochar.

Etymology

Derived from the Greek 'hemi-' meaning 'half' and 'cellulose,' reflecting its role as a related, though structurally different, component of plant cell walls that is less complex than cellulose.

In the news

In the article, hemicellulose is listed as one of the three main structural components of plant-based biomass that undergoes thermal rearrangement during the pyrolysis process to form biochar.
