b. It is a major constituent of PerlaneĀ®
c. It is a major constituent of RadiesseĀ®
d. It is a glycosaminoglycan
e. It is not available as an oral preparation

Correct Answer is C

Comment:

It is a major constituent of Radiesse®. C is false. Hyaluronan, also called hyaluronic acid or hyaluronate, is a non-sulfated glycosaminoglycan found in many tissues of the body, such as skin, cartilage, and the vitreous humour. Perlane® contains a much higher concentratation of hyaluronic acid than Restylane®. Radiesse comprises calcium hydroxyapatite particles. Hyaluronic acid can be found as oral preparations in health food shops and marketed commonly for arthritic ailments.
