Analysis

The amazing human body that we live with every day is mainly made up of really only a few molecules and even fewer atoms. Which means the structure of the cells are important. Only 3 molecules displayed on the graph is organic and then makeup-less then 50% of our body. Water is easily the most important molecule in our body since it makes up 65% of us. Protein is the highest amount of organic molecules at 18%. These molecules share a similar function in the human body which is they both fuel or aid in reactions.  Protein can be formed as enzymes that catalyze metabolism. Water, even though not an organic molecule, is needed for Hydrolysis and a by-product in dehydration synthesis. Lipids are the third most occurring, they form the cell walls of every cell in our body. These basic building blocks of life could not exist without this molecule.
