Hemicelluloses
Web7 apr. 2024 · Hemicelluloses are polymeric carbohydrates with five and six carbon atoms in the main chain. Their general formulas are as follows: pentosans ((С 5 Н 8 О 4) n) and hexosans ((С 6 Н 10 О 5) n). Hemicelluloses in coniferous woods consist of hexosans and pentosans in equal proportions, while deciduous woods consist of pentosans by 90% .
