Aspartame is an artificial sweetener that is added to food and beverages as a substitute to table sugar or sucrose. It is apparently 200 times sweet than sucrose. It is also more preferable especially in the food industry because its sweetness lasts longer than sucrose does.

The composition is 40% aspartic acid, 50% phenylalanine and 10% methanol. This compound was accidentally discovered by James Schlatter when he was trying to test an anti-ulcer drug.
