The major metabolic pathway leads to N-(3,3-dimethylbutyl)-L-aspartyl - L - phenylalanine with a side product of methanol, and the minor pathway happens when the N-(3,3-dimethylbutyl)-L-aspartyl - L - phenylalanine is oxidized into 3,3-dimethylbutyric acid. The side products for the minor pathway is methanol, aspartic acid and phenylalanine. [12]
