Lipids, Carbohydrates, Proteins And Nucleic Acids Assignment

This week you learned about the 4 types of biological macromolecules: lipids, carbohydrates, proteins, and nucleic acids. In a nutshell, a macromolecule is a very large molecule consisting of many smaller structural units linked together (like how a train is made up multiple cars linked together). All biological macromolecules are made up of a small number of elements: carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur. All cells and their organelles are made up of these four macromolecules and each type has its own specific properties and functions

In your main post, in order to help you remember the different types of macromolecules and their general structure and function, I would like you to create 2 different types of analogies for each type of macromolecule (a total of 8 analogies).
