Organic Molecules – Lipids (Fats, Phospholipids , Waxes & Steroids) Phospholipids Phospholipids are a major component of all cell membranes. Most phospholipids contain a diglyceride as the tail, and a phosphate group for head. Hydrocarbon tails ___________ , but phosphate heads are _____________ . So phospholipids are soluble in both water and oil. Tails from both layers facing inward and the heads facing outward = _________________.

Organic Molecules – Lipids (Fats, Phospholipids, Waxes & Steroids ) Waxes Do not have a hydrophilic head: so completely water insoluble. Steroids The central core of a cholesterol molecule (4 fused rings) is shared by all steroids. Cholesterol is precursor to our ____ hormones and Vitamin ___. Our cell membranes contain cholesterol (in between the phospholipids) to help keep membrane “fluid” even when exposed to cooler temperatures.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
