Cell membrane constitution and construction and resulting characteristics

What sorts of member molecules may be distributed asymmetrically? Why does it make sense for certain components of membranes to be asymmetrically distributed? Give specific examples. How can a membrane maintain asymmetry despite its fluid consistency?

Do lipids make a good soap?

You are the owner of a company that sells cleaning products. The people in Research have two new products for you to review.
