Complete hydrolysis of a nonapeptide gave 3 ala, 2 phe, 2 asp, gly, and ser. Reaction of the nonapeptide with Sanger's reagent (

1-fluoro-2,4-dinitrobenzene) followed by hydrolysis gave N-(2,4-dinitrophenyl) alanine. Partial hydrolysis of the nonapeptide gave the following fragments: gly-ala-phe ala-asp-gly-ala phe-ser-ala ser-ala-phe-asp. Which one of the following is the nonapeptide's pripary structure? A) ala-asp-gly-ala-asp-ala-phe-sor-phe B) ala-asp-gly-ala-phe-ser-ala-phe-b C) ala-phe-asp-gly-ala-asp-ser-phe-ala D) gly-ala-phe-ser-ala-phe-asp-asp-ala

Answer:

Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain

ala-asp-gly-ala

gly-ala-phe

phe-be-wing

be-wing-phe-asp

We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"

Orlov [11]

The priority after administering is to assess fetal heart rate. After administering an opioid to a laboring mother, the main concern is to evaluate the effect on the fetus. Opioid administration can cross the placental obstruction with signs as well as measuring heart rate and variability. Subsequently after birth, there may be a reduction in attentiveness. Maternal factors of a reduced blood pressure, constipation and dry month are of a lesser importance.
