The Nitrogen Cycle
All life requires nitrogen-compounds, e.g.,
proteins and nucleic acids.
Air, which is 79% nitrogen gas (N2), is the
major reservoir of nitrogen.
But most organisms cannot use nitrogen in
Plants must secure their nitrogen in
cell Dysfunction and Diabetes
Insulin resistance lead to the increase need for
Increased demand leads to exhaustion of the
cells and ultimate failure.
The cells may also

MOLECULAR SIEVE (GEL EXCLUSION) CHROMATOGRAPHY
The gel exclusion chromatography is a technique used to separate solutes that are present in a m
Protein Purification Techniques
Often the first step in a purification protocol and
takes advantage of the different solubilities of
proteins in differing concentrations of salt.
The salt often used is ammonium sulphate (NH4)2SO4
Weigh 200 300 mg of liver in a top pan balance.
Cut into small pieces with scissors and place in 10mL of cold cacodylate buffer.
Keep the homogenizing tube on ice
Use a cheesecloth to filter liver extract.
Using a 1:20 ratio dilute the filtered liver ex

For 0.5 mL of aliquot glucose content
X = 0.004/2.2663
= 0.00176 micro mole
In 1.0 mL of aliquot glucose content = 0.00176/0.5 = 0.003529 micromole/ml
For 1.0 mL of aliquot glucose content
0.009/2.2663 = 0.003971 mic
