Do you not understand what they mean, or how to use them?
1. You can often take an adjective and convert it to the noun form with the "of" as follows:
Can I be helpful? Can I be of help?
Would this be useful? Would this be of use?
That was interesting. That was of interest.

2. Of X origin - from X.
