The complex cellular membrane
- Researchers have identified thousands of different lipid structures in cell membranes. When making synthetic vesicles-synthetic lipid bilayer membranes -mixtures with monoacyl lipids can destabilize the system - so how are these avoided?
- Lipid bilayers surround subcellular organelles, such as nuclei and mitochondria, which are themselves microsystem assemblies. Each of these has their own lipid composition, different from the host vesicle.
- Lipid bilayers have a non-symmetric distribution between inner and outer surfaces.
- Protein-lipid complexes are the required passive transport sites and active pumps for the passage of ions and molecules through bilayer membranes, often with high specificity.
- All lipid bilayers have vast numbers of polycarbohydrate appendages, known as glycans. These are essential for cell regulation. Consider the hexamer of the carbohydrate D-pyranose >1 trillion constitutional and stereochemicalisomers. Eliminating any class of carbohydrates from an organism results in its death.
So how do the Ool researchers address the prebiotic synthesis of these complex lipid bilayers? They don't.
Lol.. it’s not 1840.. very few minds follow the psuedo science of evolution with the flood of scientific proof that it is utter nonsense. Is their a brownsitrs section to post it too? :)
“But regardless of where you ultimately land on the question of what conclusions science should or shouldn’t allow, and whether or not you ultimately affirm that this gold rush of new evidence points to the workings of foresight, I urge you to inspect the evidence. Curiosity may have killed the cat, but it’s done wonders for the scientific enterprise.”
Kill everyone south of a 100 IQ, and we might have a fighting chance at developing rational policies based upon a logical, fact-based analysis of science.
That video by Dr. James Tour is very good.
