[...] residues (lipophilic end). However, the polar end is not quite polar enough to make diglycerides self-assemble on contact with water, unless they are mixed with other lipids, like phosphatidylcholine (PC). This [...]

Comment on Lipid Rafts and a Possible Cure for Cancer That Could Go Viral by Dr Samuel Furse » A Raft of Concern About HIV

Dr Samuel Furse » A Raft of Concern About HIV — Sun, 31 Mar 2013 23:14:11 +0000

[...] idea of a local collection of lipids for virus budding is not inconsistent with that of lipid rafts. There is some debate about how they arise in the context of viral budding, and it is not clear how [...]

[...] a dominant influence on the curvature of the assemblies they form, and can even be divided up into ‘types’ on this basis. However, types 0, I and II (Figure 1) seem rather indistinct when we consider how slight curvature [...]

[...] machinery that lipids comprise. There is already evidence that lipids that suffer oxidation can be recycled in ocular systems, but there is now evidence that this is type of ‘damage-repair’ occurs in a model gastropod [...]

[...] provides an excellent way of doing this: it allows a lot of matter that is not water-soluble, to be washed away, bacteria included. What you might not expect is that a good detergent will also dissolve [...]

[...] provide a barrier between the toxic compound and the aqueous system in which it is suspended. The self-assembly properties of lipids mean that the system can remain intact under physiological conditions, and [...]

[...] Whilst we understand how the cell membrane is constructed (well beyond the point of knowing that biological membranes are not flat), and what a membrane does, we also know that in order for you to be reading this now, millions [...]
