Lateral diffusion in binary mixtures of cholesterol and phosphatidylcholines.
Open accessAbstract
The lateral diffusion of a fluorescent-labeled phospholipid, phosphatidyl-N-(4-nitrobenzo-2-oxa-1,3,-diazole)ethanolamine, has been measured in binary mixtures of cholesterol and dimyristoyl phosphatidylcholine at temperatures both above and below 23.8 degrees C, the chain-melting transition temperature of this phosphatidylcholine. There is a temperature-composition region, approximately temperature less than 23 degrees C and mole fraction of cholesterol (X) less than 0.20, in which the lateral diffusion coefficient of the fluorescent probe is at least an order of magnitude smaller than it is at points outside of this temperature-composition region. At temperatures above approximately 23 degrees C there is a significant increasing cholesterol concentration, for X greater than 0.2.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
