Birth of "artificial primitive cells" that proliferates even in life (modern business) --Yahoo! News

----------- In the first to third of the serialization, we introduced a technology called "DNA Oligami", which uses DNA (deokylivobic acid) as a material. And in the fourth to sixth, the DNA Oligami combined the small tube and the protein of kineshin to focus on the nano -sized robot of making a flock and the technology to create artificial muscles. The original role of these DNAs and proteins is to convey genetic information in the living body and carry various substances. Humans are trying to use it in a completely different way. It is not very noticeable, but our body has another important substance called "phospholipid". It is the material of the "cell membrane", which is a DNA and protein vessel. Recently, it has been found that even the unpleasant membrane alone can be deformed or divided. From this time, let's take a look at the possibility that it has been hidden in phospholipids, which has been attracting attention in research on the origin of life. ---------- [Image] Crawling like earthworms and gathering "proteins"

Cell membranes are made of substances similar to detergent

　Is it surprising to say, "Cell membranes are like soap bubbles?" It is that soap bubble that floats in the air, flies to the roof and breaks and disappears. I don't think it's a bit of such an unreliable thing that makes up our body. However, from a chemical perspective, both are the same in the sense that they are a "two -minute dyed membrane" made of "parent medium". Parent -oriented molecules are molecules that dissolve in water and oil are also called "surfactants". In other words, it is detergent. As you know, water and oil are usually not mixed with each other. However, if there is a parent -oriented molecule, it will be a mixture and water and oil will be mixed. That's why the oil stains on the dishes can be removed with water and detergent. And a two -molecular membrane means a film made of two layers (double) of this parent's neutral molecule. The soap bubble membrane is only about one micrometer (1/1000 millimeter), but it is actually made of two films, and the gap contains water. When the light hits it, it is divided into light reflected in the first membrane and the light reflected by the second membrane, and it is a rainbow -like pattern because it is strongly and weakened with each other (interferes). It goes up. Soap water is used for soap bubbles and kitchen detergents, but it is not such a detergent that constitutes a cell membrane. There are several types, and it is called "phospholipid" when putting it together. Roughly, as the name suggests, you can think of it as "fat containing phosphorus". However, "fat" is a solid image, but phospholipids can also indicate the properties close to liquid.
