Question

In cartilage, the proteoglycan present is attached with which of the following?

• A. Chondroitin
• B. Cassin
• C. Ossien
• D. Lacunae

Answer 1

The correct option is A Chondroitin

Chondroitin is an important vital part of cartilage. It is composed of long chain of alternating sugars which are N-acetylgalactosamine and glucuronic acid and is attached to proteins as a part of proteoglycan which is a chain of heavily glycosylated proteins. It also helps in retaining water in the cartilage. On the other hand, ossien is matrix protein of bone, also known as collagen of bone.

So, the correct answer is 'Chondroitin'.
