What is a polymer? Polymers are substances containing a large number of structural units connected by the same type of bond. As soon as you hear the word polymers, you assume it's made in huge chemical factories. In fact, polymers have existed in nature since the beginning. All living things, plants, animals and humans, are made of polymers. However, what you don't know is that they are different types of polymers: synthetic polymers that use harmful toxins to be synthesized and those that are natural. These are many polymers that fall into the natural process and are used both in our society and in our body, which are cellulose; starch, rubber, proteins and both are DNA and RNA, and many more. To begin with, cellulose is made up of glucose units naturally found in plants, for example corn. Since all plants produce it, it is probably the most abundant organic compound on Earth. Besides being the primary building material for plants, cellulose has many other uses. Cellulose is used as a precursor in the production of ethanol. Then, the glucose is fermented by yeast to produce ethanol. Ethanol is a major product because it is used in alcoholic beverages, and...... middle of paper......, natural polymers participate in the construction of our society and our body. A long time ago, before the advent of plastics and synthetic polymers, in fact, from the beginning of Earth, nature used natural polymers to make life possible. We don't consider natural polymers to be in the same league as synthetic polymers because they are made with immense chemicals. However, this does not make natural polymers any less important; it turns out they are the most important in many ways. To summarize, natural polymers include proteins, which are contained in our body, and RNA and DNA are so important in genes and starches that we make from food and we build things and make clothing from cellulose.
