Chlorophyll contamination in extracts

I have been having a discussion on another forum, on how it is possible for water to pickup chlorophyll in an extraction, when chlorophyll is basically a hydrocarbon, which is mostly insoluble in water.

I did enough research to know that I was in over my head with chemistry that I took on the late fifties and early sixties, so I asked Joe, our budding biochemist, to take a run at it.

In quick summary, before Joe’s response, “define soluble?” The word soluble means different things in biochemistry, than it does in inorganic chemistry, because of the behavior of the molecules of life.

The chlorophyll molecule has a magnesium (Mg) at its ringscenter, which makes it ionic and water-loving (hydrophilic) and a ring that is water fearing (hydrophobic) with carbonyl groups near a tail that make it polar (also hydrophilic).

    I slowly heated my extracted matter until it was soft and whip-able. Question: will prolonged heat ruin my extraction? It was over a low heat for a few hours while i waited for it to stop bubbling. Bubbling I understood was the butane evaporating. Am I misunderstanding? I was worried about the effects of prolonged heat so I removed it.
