Stoffwechselweise

Stoffwechselweise is a German expression formed from Stoffwechsel (metabolism) and -weise (way, manner). It is not a standard technical term in biochemistry; rather it appears in less formal or didactic writing to indicate the way metabolism operates in a given context. Rough translations include “metabolically speaking” or “in metabolic terms.”

In use, the term signals a broad description of metabolic organization rather than the details of individual reactions. It can be used to describe the overall orientation of metabolism under specific conditions, such as predominance of catabolic versus anabolic activity or substrate preference, without listing the specific pathways involved. Because Stoffwechselwege (metabolic pathways) are the more precise concept, Stoffwechselweise is typically reserved for a high-level characterization rather than experimental reporting.

Because it is informal and context-dependent, its meaning can vary between authors. Some writers may juxtapose Stoffwechselweise with more precise terms like Stoffwechselwege or Stoffwechselregulation to contrast the overall metabolic state with specific steps or regulatory mechanisms.

As a linguistic note, the term reflects German tendencies to form adjectives and adverbs from compound nouns to convey nuance. For readers, the term conveys a metabolic orientation rather than a fixed pathway description. See also metabolism, metabolic pathways, and metabolic regulation.
