Aminoacidmonoaminomonocarboxilic: CnH2n+1NO2
2CnH2n+1NO2 -> C2nH4nN2O3 + H2O
Mdipeptid........................100%
28g..................................17,5%
Mdipeptid=28*100/17,5=160g/mol
Mdipeptid=12*2n+4n+14*2+16*3=28n+76=160
28n=84 => n=3
CH3-CH(NH2)-CO-NH-CH(CH3)-COOH (alanil-alanina sau ala-ala)
