Amelia the Amoeba is the protagonist of a chapter of my book ” Before the Collapse ” (Springer 2019). She is a Naegleria Fowleri who has the rather nasty habit of devouring human brains but, apart from this, she kindly lent herself to be an example of the mechanisms of growth of living creatures. In the following post, Alessandro Chiometti again uses the example of single-celled creatures for an interesting discussion on how our brains are destroyed, not by a brain-eating amoeba, but by an excess of available information. As a post, goes a little against the principles of modern “throwaway information”, in the sense that rather than starting with trying to impress you with some flashy information, it gives you a little lesson in chemistry. But if you feel like working on it just a little, you’ll see that it is a very interesting and thought-provoking post. It suggests that too much information is doing to us the same thing that too much sugar could do to Amelia: it kills our brains. And you’ll learn some chemistry, too! (UB)
We are used to call “sugar” a substance that is actually sucrose, one of the many existing “sugars” which are referred to in organic chemistry as carbohydrates. These compounds can be formed by a single molecule of any sugar (monosaccharides) or by several molecule (polysaccharides). Sucrose is a disaccharide formed by the union of the two monosaccharides, glucose and fructose.
Although these two molecules have the same brute formula (C6H12O6) in reality they are very different: glucose forms a six-atom ring while fructose forms a five-atom one but, above all, it is glucose that is the primary source of energy for every living being.
