Aspartame is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages. In the European Union, it is codified as E951. Aspartame is a methyl ester of the aspartic acid and phenylalaninedipeptide.IUPAC name: N-(L-α-Aspartyl)-L-phenylalanine 1-methyl esterStructural formula can be found in 'Reated Links' below this answer.
There are two nitrogen atoms in aspartame. One is a primary N in R-NH3, while the other is a secondary N in R-NH-R (R represents the rest of the carbon structure). Since both N has three substituents in addition to the already present lone pair, they both have 4 groups attach to them. Thus, they are both sp3 hybridization.
