Consider the hypothetical serine protease, which shows the specificity pockets. The S1S1 pocket has a glutamic acid in the bottom, the S2S2 pocket is small and hydrophobic, and the S1'S1' pocket is deep and hydrophobic. Suggest an amino acid sequence that this protease would cleave. Which of the sequences would this protease cleave? a) Ile-Lys-Ala

b) lle-Ala-Lys

c) Lys-lle-Ala

d) Lys-Ala- lle

e) Ala-lle-Lys

f) Ala-Lys-lle

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

a electronegativity decreases beacuse the size of nucleus is bigger.
