Macromolecules in cells

Macromolecules are a large class of molecules very important biologically. There is also the term monomer that comes from a greek word. Mono meaning one and meros meaning part which is what they are made of. Different molecules that when are pulled apart form a different function. They are chemically bonded together to form long multipart polymers. Polymers you may know is a very difficult term but it has the most basic meaning in the world. Polymer means a large molecule made up of similar or identical subunits called monomers. You may know with every class their must at least one or two main subunits but in this class their is four which all behave differently. They are protein, carbohydrates, lipids, and nucleic acids. You may know if you have taken health that all of these main components show up in your daily life but the one that I found most interesting was carbohydrates. They make up most of our diet and are showed up in many of our foods but it doesn't only show up in our food. I bet you didn't know that some molecular structures of carbohydrates are found on cancer cells and help doctors tackle the cancer before it finally spreads throughout your body and takes its course in making you weak. Just like when you have a glucose molecule and  galactose molecule one little switcheroo will make the name change and the way it behaves. The oh and the h will be switched and that is when galactose is formed. But most importantly you have to know how a macromolecule is formed and what it is formed by. Macromolecules are formed by condensation reactions and are broken down by hydrolysis.  Making many new ingredients that are used in our diets today. Such as the glucose that is in our fatty foods.
