The detectives re-interviewed Lee Merryweather to follow up on information uncovered since their last conversation. Read more ... Ray Jennings follow-up interview
Sterols are a subgroup of steroids with a hydroxyl group at the 3-position of the A-ring. They are amphipathic lipids synthesized from acetyl-coenzyme A via the HMG-CoA reductase pathway. The overall molecule is quite flat.terols are a subgroup of steroids with a hydroxyl group at the 3-position of the A-ring.

The steroids are a family of lipids based on a molecule with four fused carbon rings. This family includes many hormones and cholesterol. Cholesterol is a component of the cell membrane in animals and functions to moderate membrane fluidity because it restricts the motion of the fatty acid tails.ats, steroids, and phospholipids are very important to the functioning of membranes in cells and will be the focus of this tutorial. Fats (triacylglycerols, triglycerides). Fats are synthesized from two different classes of molecules: fatty acids attached to the alcohol glycerol.
