PROCESS FOR PRODUCING NOVEL SIALO-SUGAR CHAIN
Provided are: a novel sialo-sugar chain
a process for producing said sialo-sugar chain
and production equipment for said sialo -sugar chain. The novel sialo-sugar chain can be easily and efficiently mass-produced by reacting a sugar wherein one of the hydroxyl groups is substituted with an alkynyl group (hereinafter, said sugar being often referred to as "an alkynylated sugar") with a specific sialic acid donor in the presence of a sialic acid-introducing enzyme.
