bodymetabolizable
Bodymetabolizable is a term used to describe the portion of a substance that the body can metabolize to yield energy or synthesize tissues, after digestion and absorption. It is a concept used in nutrition science to distinguish the metabolizable fraction from the total or gross content of a compound. In practice, researchers typically discuss metabolizable energy (ME) or metabolizable protein (MP), while “bodymetabolizable” may be used informally to indicate the biologically usable portion of a nutrient.
The concept depends on several steps: digestion in the gastrointestinal tract, absorption of digestion products into
Measurement methods include controlled feeding trials that compare gross energy intake with losses in feces and
Factors influencing bodymetabolizable fraction include chemical form (e.g., starch versus resistant starch), degree of processing, presence
Use of the term is mainly theoretical or informal. When precision is required, scientists prefer established
