Wewaii [24]

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"

Aminosyn is an amino acid often times used in tpn orders to provide protein for cellular repair and growth. a physician writes a
love history [14]
I think theres a few methods to do it, but this is probably the most efficient.

Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin

Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.

To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%

Therefore 1% = 12.5/8.5= 1.470588

Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml

Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
