Modelling amino acid efficiency

The absorption of amino acids is dictated by several factors that affect the transport system such as operational characteristics, kinetics behaviours, mode of energization and substrate recognition (Guidotti and Gazzola, 1992). Because the transport mechanism is specific to amino acids or group of amino acids (Stevens, 1992), one amino acid that is in excess may compete with the absorption of another amino acid that uses the same transport system. Therefore, a model to compute the likelihood of an amino acid being absorbed given the concentration of amino acids and transport system specificity could be used to generate dynamic absorption coefficients that are sensitive to amino acid imbalances.
