Egg Yolk	Walnut
Mass of lipid source (g)	1.0105g	0.987g
Volume of lipid extract (lower phase) (ml)	0.5ml	2ml
Mass of empty crucible (g)	71.734g	64.22g
Mass of crucible with dry total lipids (g)	71.806g	64.732g

A) Which of the two sources contains more lipid in g/g (lipid source)?

B) Calculate the % cholesterol in the total lipid content Egg Yolk and Walnut samples. (Molecular weight of cholesterol = 386.66gmol^-1) given 0.537 = 0.0674x + 0.1554 = 5.66 nM Conc. Of cholesterol in egg yolk

C) Do your answers coincide with literature values?

literature value ->LARGE EGG YOLK= 186mg cholesterol

If not, can you suggest a reason why.
