#112 Dry matter/dry weight

[Anonymous]

The most frequently substance unit in constraint-based modeling is millimole per gram dry weight. The mass part is often abbreviated as gDW and refers to the dry matter fraction of the probe used (see https://en.wikipedia.org/wiki/Dry_matter). When using the unit gram to indicate the mass part of the composite unit mmol/gDW it would be desirable to have a specific SBO term that allows modelers to indicate that gDW is the mass of the dry matter fraction and not of the total probe.

The description of the term could point out that there are multiple methods available to obtain the dry matter from a probe. Modelers should therefore be encouraged to also indicate which of these methods was used in their experiment. This could be done, e.g., by using further annotations of the unit.
