A 65-year-old patient complains of

occasional
swelling, pain, and a scraping sensation in the knees. X-rays show a narrowing
of the joint space. The patient only wants
to take "natural" oral products to help reverse
this condition.
The products available for
consumption
are examples of which one of the
following types of compounds?
(A) Proteoglycan
(B) Polyol
(C) Glycolipid
(D) Disaccharide
(E) Glycoprotein

Answer 1

The available products for consumption to help reverse osteoarthritis are examples of proteoglycans.

Step-by-step explanation:

The condition described in the question is osteoarthritis, which is associated with aging and 'wear and tear' of the articular cartilage. The narrowing of the joint space seen on X-rays is a characteristic feature of osteoarthritis. The patient wants to take 'natural' oral products to help reverse this condition, and the products available for consumption are examples of proteoglycans. Proteoglycans are large molecules composed of proteins and glycosaminoglycans (GAGs) that are found in the extracellular matrix of connective tissues, including articular cartilage.
