Question

Problema 988, va rog!

Answer 1

H2NOC-CH2-CH(NH2)-CONH-CH(CH3)-COOH + NaOH ⇒  NaOOC-CH2-CH(NH2)-CONH-CH(CH3)-COONa + H2O

1 mol Asp-Ala ___  mol NaOH

=> 2 moli Asp-Ala __ va neutraliza x moli NaOH

=> x = 2 moli NaOH

Cm = n / Vs => Vs = n / Vs = 2 / 0,1 = 20 L sol NaOH

Am reeditat.. raspunsul... si anume..

asparaginil = monoamida acidului asparagic asadar in Asparagil-Alanina vom avea liber doar 1 grupare -COOH

=> A, E
