生物活性

Aspartame (SC-18862) is a methyl ester of a dipeptide. Aspartame can be used as a synthetic nonnutritive sweetener. Aspartame is composed of phenylalanine (50%), aspartic acid (40%) and methanol (10%)[1][2].

体外研究
(In Vitro)

Aspartame is composed of phenylalanine (an important role in neurotransmitter regulation), aspartic acid (an excitatory neurotransmitter in the central nervous system) and methanol[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Aspartame (4000 mg/kg bw/day; p.o.) shows no adverse effect in acute, subacute and chronic toxicity studies with aspartame, and its decomposition products, conducted in mice, rats, hamsters and dogs[1].
