NutritionalRoleEnum

Name
NutritionalRoleEnum
Description
What element or macronutrient an ingredient supplies to the medium. One of three orthogonal role facets (with PhysicochemicalRoleEnum and CellularMetabolicRoleEnum). A single ingredient may carry multiple nutritional roles (e.g. L-cysteine supplies both amino-acid and sulfur).

Permissible values
Carbon source
Text
CARBON_SOURCE
Description
Provides organic carbon for biosynthesis and energy.
Mappings
  • METPO:2000006
Nitrogen source
Text
NITROGEN_SOURCE
Description
Provides nitrogen for amino acids, nucleotides, and other biomass components.
Mappings
  • METPO:2000014
Sulfur source
Text
SULFUR_SOURCE
Description
Provides sulfur (typically for cysteine, methionine, Fe-S clusters).
Mappings
  • METPO:2000020
Phosphate source
Text
PHOSPHATE_SOURCE
Description
Provides phosphate for nucleotides, phospholipids, and energy carriers.
Iron source
Text
IRON_SOURCE
Description
Provides iron (typically for cytochromes, Fe-S clusters, and other metalloproteins).
Trace element
Text
TRACE_ELEMENT
Description
Provides a micronutrient required in trace amounts (e.g., zinc, cobalt, manganese, molybdenum).
Mineral source
Text
MINERAL_SOURCE
Description
Provides a bulk inorganic mineral nutrient not covered by a more specific element-source value — in practice the macronutrient cations magnesium, calcium, potassium, and sodium (e.g., MgCl2, CaCl2, KCl, NaCl). Prefer the specific value (PHOSPHATE_SOURCE, IRON_SOURCE, SULFUR_SOURCE, TRACE_ELEMENT) whenever the salient nutrient is one of those; MINERAL_SOURCE is the residual bucket, mirroring how TRACE_ELEMENT buckets the micronutrient metals.
Vitamin source
Text
VITAMIN_SOURCE
Description
Provides vitamins or vitamin precursors.
Meaning
CHEBI:33229
Amino acid source
Text
AMINO_ACID_SOURCE
Description
Provides one or more specific amino acids as building blocks.
Mappings
Protein source
Text
PROTEIN_SOURCE
Description
Provides peptides, proteins, or complex amino-acid mixtures (e.g., yeast extract, peptone, tryptone).
Mappings
Cofactor provider
Text
COFACTOR_PROVIDER
Description
Supplies enzyme cofactors or prosthetic groups to the medium (the compound acts as a source; contrast with CellularMetabolicRoleEnum.COFACTOR, which is the intracellular role).
Mappings
Energy source
Text
ENERGY_SOURCE
Description
Primary energy substrate for chemotrophic growth.
Mappings
  • METPO:2000010
Light source
Text
LIGHT_SOURCE
Description
Radiant-energy source for phototrophic growth. No CHEBI or METPO term yet describes a radiant-energy *supply* role (METPO:1000656 is the organism metabolic-mode `photoautotrophic`, not a supply-side role); METPO submission pending.
