Number of Alanine molecules
Hi, I'm a little stumped on this question if you guys could help me out it would make my day
Assume that you have hydrolyzed 7mg of a polypeptide solution of a protein with a know molecular weight of 1265. You have also analyzed the type and quantity of amino acids.
AMINO ACIDS-
alanine- Amount 0.97mg Molecular weight- 89
aspartic acid- Amount 2.19mg Molecular weight-133
cysteine- Amount 1.32mg Molecular weight- 120
glutamine- Amount 1.30mg Molecular weight-119
Serine- Amount 1.15 Molecular weight- 105
What is the number of alanine molecules in the polypeptide chain? This is a 3rd question after they asked the ratios of each amino acid to one another.
I just don't know how I should work the number out, thanks!
