Biological cell surfaces present dense areas known as “glycocalyx” with the carbohydrate systems conjugated to lipids or proteins. 1 This led to the concept of a “glycocode”, in other words biological information transfer by sugars. 2 This spatial coding offers huge numbers of structural permutations for oligosaccharides sequences through variation of glycosidic linkage position as well as orientation. There appear to be two forms of recognition through which carbohydrates can ...
