[New data on glycosaminoglycans and proteoglycans].

The most important investigations on glycose aminoglycans and proteoglycans, carried out within the recent 5-7 years, are reviewed. Data on primary structures repeating in glycose aminoglycans and on relationship between these biopolymers and protein components in proteoglycans are considered. Newer information on conformational characteristics of glycose aminoglycans, various complexes aggregation of proteoglycans and distribution of the biopolymers in animal tissues and cells is discussed. Properties of proteoglycans in various solutions are briefly considered.
