Chondroitin sulphate and keratan sulphate are almost isosteric.
Keratan sulphate and chondroitin sulphate (KS and CS) in the 2-fold helical configurations that are prevalent in solution are of very similar tacticity. The chiral centres, anionic sites and hydrophobic patches are in identical conformations. Only the position of the acetamido group varies from CS to KS, but part of its intramolecular H-bonding potential in CS is retained in KS. The formation o...
متن کاملZonal distribution of chondroitin-4-sulphate/dermatan sulphate and chondroitin-6-sulphate in normal and diseased human synovium.
OBJECTIVES Chondroitin sulphate is the major sulphated glycosaminoglycan present in the extracellular matrix of soft connective tissues and the aim of this study was to investigate the distribution of chondroitin sulphate species in normal and diseased synovium. METHODS Distribution of chondroitin-4-sulphate/dermatan sulphate (Ch4S/DS) and chondroitin-6-sulphate in normal (n = 6), osteoarthri...
متن کاملSynovial fluid chondroitin and keratan sulphate epitopes, glycosaminoglycans, and hyaluronan in arthritic and normal knees.
OBJECTIVES To determine concentrations of chondroitin sulphate (CS) and keratan sulphate (KS) epitopes, glycosaminoglycans (GAGs) and hyaluronan (HA) in knee synovial fluid (SF) from normal subjects and patients with osteoarthritis (OA) or rheumatoid arthritis (RA), to test whether these variables may be used as markers of the OA process. METHODS OA was subdivided into large joint OA (LJOA), ...
متن کاملChondroitin and keratan sulphate epitopes, glycosaminoglycans, and hyaluronan in progressive versus non-progressive osteoarthritis.
OBJECTIVE To determine if a single time point estimation of chondroitin sulphate (CS) or keratan sulphate (KS) epitopes, hyaluronan (HA), or total glycosaminoglycans (GAG) in knee synovial fluid at time of hospital referral can predict subsequent radiographic progression of knee osteoarthritis. METHODS Two groups of hospital referred patients with knee osteoarthritis were compared: (1) a "pro...
متن کاملNature of the interaction of chondroitin 4-sulphate and chondroitin sulphate-proteoglycan with collagen.
The electrostatic interaction of chondroitin sulphate and the chondroitin sulphate-proteoglycan with collagen was studied by chromatography of the glycosaminoglycan and the proteoglycan on a collagen gel. The observed binding between the macromolecules increased with decreasing pH and ionic strength, and was significant under physiological conditions. A study of the interaction between chondroi...
