The human body is about 60-100 trillion cells, these cells formed many cell group. Each group of cells in different ways adhered to each other, between cells and the matrix also exist mutual recognition and interaction, between the group and the mutual recognition, interaction and mutual restriction, regulation and control of higher organisms along the natural space and time axis orderly development. In such a complex development process required extremely huge bioinformatics only by the amount of information contained in the sugar chains of molecules for nucleic acid and protein is several orders of magnitude greater than to bear. This led to the birth of "sugar" in biology.

Scientists to study of in vivo polysaccharide of science called "sugar biology", it was also followed "genome" and "proteomics" concept to the subject called "glycomics" and its research field is carbohydrate chemistry, sugar chain biosynthesis, sugar chain in the organism function, sugar chain operations and technology.
