Glycosaminoglycans, Proteoglycans & Glycoprotein
Hi, after long time Today, we will explain Glycosaminoglycans, Proteoglycans and Glycoprotein but before we start, we will make a quick revision for basics of carbohydrates. Revision: Carbohydrates have general formula (CH2O)n , where n ≥ 3. They are classified into monosaccharides (simple sugar such as glucose), disaccharides and polysaccharides. They can also be classified into aldoses (-CHO) and ketoses (-CO) where: Enantiomers are special type of isomerism is found in the pairs of structures that are mirror images of each othe r where the two members of the pair are designated as a D- and an L-sugar. In the D isomeric form, the –OH group on the asymmetric carbon (a carbon linked to four different atoms or groups) farthest from the carbonyl carbon is on the right, whereas in the L-isomer, it is on the left . Cyclization: You can see anomeric carbon in the image (referred by arrow). Alpha anomer where OH on anomeric carbon is trans to
