they may stimulate directly the reaction forming dolichyl diphosphate n , n'-diacetylchitobiose from dolichyl diphosphate n-acetylglucosamine , or activate the synthesis of this latter intermediate from a particular pool of dolichyl monophosphate which is readily converted afterwards into disaccharide and oligosaccharide derivatives and glycosylates protein .
