How to get the molecular weight from the above protein properties?

L7651 Lysozyme from chicken egg white lyophilized powder, protein ...

Thank you

Where did this come from?  Is this in the manual somewhere?

In any case it's probably just an example of expected output from some utility.

Probably pertains to a single polypeptide in a larger complex, but without
proper context, that's just a guess.
