permissible_values:
alpha:
text: alpha
description: The exocyclic oxygen at the anomeric centre is formally cis, in the
Fischer projection, to the oxygen attached to the anomeric reference atom.

description: The sugar is in its acyclic form, so it has no anomeric centre.
unknown:
text: unknown
description: The configuration is not known, or is deliberately left unspecified,
