As for the Moufang identities. Since
> * The invertible elements in any alternative ring or alternative algebra form a Moufang loop.*
The answer should be yes, bioctonions (which are just octonions and hence a unital composition algebra over \(\mathbb{C}\) and thus invertible except for 0) form a Moufang loop. So the identities hold.
