We consider the plasma membrane that contains a cholesterol molar fraction of 0.4 and ask how that cholesterol is distributed between the two leaves. Because of the rapid flip-flop of cholesterol between leaves, we assume that its distribution is determined by the equality of its chemical potential...
That bending energy might be important to the cholesterol distribution was suggested by Giang and Schick (9). Noting that phosphatidylethanolamine (PE), which is found almost completely in the inner leaf, has a spontaneous curvature that is relatively large in magnitude, they suggested that ...
Protein is a structural nutrient used to grow and repair cells, among other things. Protein is only used for energy in the absence of carbohydrates, through a process called gluconeogenesis (which entails the creation of glucose from non-carbohydrate sources). On the other hand, both carbs and ...

cholesterol gets made. Therefore, the enzyme that runs this reaction, HMG-CoA reductase, is very important—it’s like the foreman in charge of the cholesterol assembly line. This enzyme needs to be carefully controlled, because we don’t want cells wasting their time and energy building ...

When stenabolic was used on mice with heart hypertrophy, the size and weight of their heart were reduced with no change in their blood pressure. The levels of good cholesterol also increased by stenabolic while the bad cholesterol was reduced. This is ideal for fitness enthusiasts because the he...
