Question

Organic or inorganic?

-Glycosaminoglycans

-Hydroxyapatite

-Fluoride

-Proteoglycans

-Sulfate

-Glyciproteins

-Provides flexibility

-Calcium carbonate

-CaCO3

-Resists tensile (pulling) forces

-Collagen

-Resists compressive forces (pushing)

-Provides hardness

-Magnesium

-Calcium phosphate

-Ca10(PO4)6(OH)12

Answer 1

Anything which contains carbon in its structure is said to be organic compound.

And compounds without carbon in their structure are called non organic compounds.

So, among the given compounds above, the organic ones are-

-glycosaminoglycans

- proteoglycans

-glyceroproteins

- provide flexibility

- collagen

- provide flexibility

- resist pulling force

- resist compressive force

Rest of the compounds are inorganic.

NOTE- Although calcium carbonate contains carbon in its structure, but it is not a organic compound. It is an exception. It is because the basic structure is of calcium, not carbon.
