I'm making a picture book and I need to draw the following, what would they look like?

Pepsin
Bile
Trypsin

What I'm asking is what do the following look like. Is it a solid or a liquid and what color. Thanks.

Thanks Ms. Sue but I still can't seem to find them.
Did you click the links above?

If that doesn't work, go to Google, click images, and type in each of the substances you need to draw.
