Hi,

Im wanting to try some alternative processes in my dark room, and I want to get the proteins/amino acids of an egg (raw or cooked) dissolved in a solution, and am wondering what kind of solvent I can use to do this.

I've tried the usual water + sodium hydroxide, which doesnt appear to work.

Thinking about making a trip to the shop to grab some mineral turpentine - non-polar solvent, and I was reading on each of the amino acids egg is made of the and some are hydrophobic - but there must be more to it then simlpy whacking it in a non-polar solvent.


I also dont actually have any acids atm (hcl, nitric or sulphuric which I need to get) apart from ascorbic acid (not ascorbate).


edit: in fact, lets say I bought some protein powder from the supermarket (i have a large an of soy based stuff here with me) - which has a wide range of amino acids - how would you go about actually dissolving it?

The first thing I thought of was Mayonnaise, which uses vinegar.
I wonder if you adjust the recipe if you can get it to dissolve the egg rather than be an emulsion.

hydrogen peroxide partially dissolves the egg.. as well is the protein powder which slowly starts to turn from opaque in water to partially transparent, but i only have 3% hydrogen peroxide.

I decided to try egg as it has a high concentration of amino acids (which all practially should be make good photographic developers if dissolved in an alkalai solution).

The turpentine did something strange and left a membrane on the bottom of my measuring cylinder with some egg yolk... which in turn left a milky opaque film on one side of the cylinder as I tried to clear it out.. oh well..
