|Grouping compounds into equivalence classes clarifies their nutrient roles|
|1||C||alpha-D-glucose, glycerol, D-mannose, D-glucarate, and 27 others|
|2||C, P||beta-D-glucose-6-phosphate,alpha-D-glucose-1-phosphate, 2 others|
|3||C, N||N-acetyl-beta-D-glucosamine, L-serine, adenosine, and 7 others|
|4||C, N||L-alanine, D-alanine, and 2 others|
The equivalence classes of compounds generated from our original minimal nutrient sets are shown here. All the compounds in an equivalence class are interchangeable in their roles in predicted minimal nutrient sets. For example, alpha-D-glucose (class 1) can substitute for glycerol, D-mannose, and so forth. Column one shows the class’ number, column two shows the elements that we believe it provides as part of predicted minimal nutrient sets, and column three lists all or a representative part of the compounds contained within the class.
