Effect of Wood Hemicellulose Composition on Binding Interactions with Caffeine

Wood is one of the important construction materials and it is necessary to protect it from biological pests. Hemicellulose in wood consist of various sugar hexoses or pentoses depending on the tree species. This composition can have significant effects on interactions with chemical substance as bioc...
