cholesterol has an insoluble nature - because its used in cell membranes

haemoglobin has the hydrophobic part on the inside and hydrophilic part on the outside because it needs to be water soluble

A popular and straightforward  quiz to check your understanding of biological molecules and biochemical tests. I have edited some questions to improve clarity.  The correct plural for helix is helices.
