That's my question. If true, it would make my job a lot easier. I will appreciate any feedback on the matter. 




Seems I underestimated this problem.


First passage from Wikipedia is crucial:



> 
> An alicyclic compound is an organic compound that is both aliphatic and cyclic.

And second is wrong:



> 
> They contain one or more all-carbon rings(...)

[Glucose](https://en.wikipedia.org/wiki/Glucose) is **carbohydrate**, in its circular form which is found in [glycans](https://en.wikipedia.org/wiki/Glycan) (also glucose isn't a glycan, but glucose residue is found in many of them) it has oxygen atom in the ring - according to second passage from Wikipedia it therefore shouldn't be alicyclic, but one can easily find mention about alicyclic ethers for ex. [here](http://www.nrcresearchpress.com/doi/pdf/10.1139/v68-161), with oxygen in ring. So I'm changing my answer to:


**Yes, they are.**
