In
the cartilage matrix,
|
|
|
individual
proteoglycans
|
|
|
(in box, from before) are
|
|
|
linked
to a nonsulfated
|
|
|
GAG,
called hyaluronic
|
|
|
acid, to form a
giant
|
|
|
complex
with a molecular
|
|
mass of
about 3,000,000.

The
box indicates one of
|
|
|
the
proteoglycans of the
|
|
|
type
shown in first slide.
