  • J Joules The unit of energy. S Steroid A lipid derived molecule E Emulsion What E is formed when there is a positive result for a fat test? V V-max Rate of reaction levels off when all the active sites
  • Test for a lipid: Emulsion test: Add 2cm3 fat or oil to a test tube containing 2cm3 of absolute ethanol. Dissolve the lipid by shaking vigorously. Add an equal amount of cold water. Observation:
  • The steroid hormones are lipid-soluble so can easily pass through membranes by lipid diffusion. They diffuse to the nucleus, where the bind to a receptor, which activates protein synthesis. (E.g. testosterone
