| A | Mucin in stool | |
| B | Protein in CSF | |
| C | Hyaluronate in synovial fluid | |
| D | Protein in pleural fluid |
| A | Mucin in stool | |
| B | Protein in CSF | |
| C | Hyaluronate in synovial fluid | |
| D | Protein in pleural fluid |
Hyaluronate in synovial fluid
All are examples of glycosaminoglycans, EXCEPT:
| A |
Hyaluronic acid |
|
| B |
Chondroitin sulfate |
|
| C |
Heparin |
|
| D |
None of the above |
Hyaluronic acid – mucopolysaccharide is present in
| A |
Cornea |
|
| B |
Mast cell |
|
| C |
Vitreous humor |
|
| D |
Dermis |
C i.e. Vitreous humor
Heparin is –
| A |
Polysaccharide |
|
| B |
Lipoprotein |
|
| C |
Monosaccharide |
|
| D |
Polyenoic acid |
Ans. is `a’ i.e., Polysaccharide
o Heparin is mucopolysaccharide.
Uronic acid pathway does not have a role in the formation of which Proteoglycan:
| A |
Keratan sulfate |
|
| B |
Chondroitin sulfate |
|
| C |
Hyaluronic acid |
|
| D |
Heparan sulfate |
Glycosaminoglycans are heteropolysaccharide (heteropolysaccharides are polysaccharides which contain two or more different monosaccharide unit or their derivates).
Keratan Sulfate- It is the only GAG that does not contain any uronic acid. The repeating units are galactose and N-acetyl glucosamine in the beta-linkage. It is found in cornea and tendons.
Mucopolysaccharide having anticoagulant action is‑
| A |
Heparin |
|
| B |
Phenindione |
|
| C |
Rivoroxaban |
|
| D |
Dabigatran |
Ans. is ‘a’ i.e., Heparin
Heparin
- It is a parenteral indirect thrombin inhibitor.
- It is a on uniform mixture of straight chain polysaccharides with molecular weight 10, 000 – 20, 000.
- It contains polymers of two sulfated disaccharide units D glucosamine L iduronic acid and D glucosamine D glucuronic acid.
- Heparin is the strongest organic acid present in the body.
