The Five Compounds in the Human Body

Author's Note:  This is my science paper.  I chose the topic about the five compounds in the human body, because I'm an athlete, and when I saw fats, proteins, and carbohydrates, I immediately wanted to know the purpose for these compounds.  Learning about them has helped me to eat healthier.


What if I told that out of all the organic compounds in your body, there are only five necessary for life?  Eating the right foods and staying healthy are the best ways to supply these five compounds.  But first things first, what exactly are the five organic compounds necessary for life? 

One of these compounds is fats/oils.  Without fats and oils, several things go wrong.  Fats and oils are responsible for maintaining a healthy circulation and a healthy immune system (Simon), so these areas would be negatively affected.  Also, vitamins A, D, E, and K wouldn’t be properly distributed through the bloodstream (Fat Nutrition) — another negative.  Lastly, because fats and oils are one of the three nutrients that supply the body with calories, you would have energy loss  (Fat Nutrition).  Since the body relies on stored fat for calories, after the first 20 minutes of exercise when carbohydrates supply has been expended (Fat Nutrition), you will develop fatigue very quickly without an adequate supply of fats and oils.

Though fats and oils are essential, you have to consume the correct fats in the correct proportions.  Saturated fats are very unhealthy fats.  Eating extensive amounts of these fats increases the risks of heart disease and cholesterol build up (Fat Nutrition).  Limit your saturated fat intake so that it supplies only 10% of your calorie intake (Fat Nutrition).  Unsaturated fats help lower your cholesterol, but have a higher calorie make up, so you still need to limit these fats (Fat Nutrition). 

Besides fats and oils, carbohydrates are another compound necessary for life.  They are also another one of the three nutrients that supply the body with calories. Carbohydrates actually are the nutrients that most calories should come from, between 40% to 60% (Carbohydrates).  You are probably already thinking about eating fewer carbohydrates to reduce calories in order to lose weight, but that is not the right way to go about it. 

Decreasing your carbohydrate intake either results in low calorie consumption or increase of fat consumption to make up for lack of calories (Carbohydrates).  Both ways result in an unhealthy body because the first way does not supply enough calories to run the body properly, and the second way increases the risk of heart disease and cholesterol build up.  On the other hand, eating excessive amounts of carbohydrates increases the risk of obesity (Carbohydrates, due to the high amount of calories being unused and stored.  Also, besides proportions, choosing the right carbohydrates is very important.  Foods with complex sugars, such as fruits and vegetables, are healthiest.  This is because, unlike processed simple sugars, complex sugars contain not only calories, but also vitamins, minerals and fiber (Carbohydrates). 

Like fats and carbohydrates, proteins are another compound that supplies calories.  Though they provide calories, a protein’s main function is to repair and maintain the human body, which is why foods high in protein content are very popular for athletes.  Be careful though when consuming excessive amounts of protein because too much may result in putting strain on your kidneys.  On the other hand, eating low levels of proteins will reduce the lean body weight. 

Eating the correct amount of protein is important, but you also have to watch what proteins you are eating.  Basically, there are two types of proteins, essential and nonessential.  Essential proteins are proteins your body can only receive from foods (Protein in Diet Nutrition).  The difference between essential and nonessential proteins is that the body can produce nonessential proteins using substances already found in the body (Protein in Diet Nutrition).  No matter if it’s essential or nonessential, these proteins are broken down into amino acids and enter into the bloodstream where they are used to make enzymes and structural proteins (How Cells Work).

The enzymes that amino acids help make are used throughout the body.  The basic function an enzyme has within a cell is to let the cell conduct rapid chemical reactions (Brain).  When needed, these chemical reactions let the cell build or take things.  This process is what makes the cell grow and reproduce (Brain).  Also, the more important a chemical reaction is to a cell and the more often the reaction is needed, the more of the same type of enzymes are produced (Brain).

An enzyme’s function is to build or take things, but they are also the reason for certain deficiencies.  For example, lactose intolerance is where the lactose in milk does not get broken down to its glucose components, making it indigestible (Brain).  This is due to a malfunction of the enzymes that are supposed to break the lactose down.  This problem can actually be fixed by swallowing a drop of lactase before consuming dairy.  However,  many enzyme deficiencies aren’t solved so easily (Brain).

The final organic compound necessary for life in the human body are nucleic acids.  DNA is, without a doubt, the most famous nucleic acid, but some other ones are RNA, mRNA, and tRNA (Biochemistry:Nucleic Acids).  All of these nucleic acids are used to help cells copy and make proteins (Biochemistry:Nucleic Acids).  DNA also has another job that is important in the reproductive process.  Nucleic acids let organisms transfer genetic information from generation to generation (Bailey).  DNA, which actually stands for deoxyribunucleic acids, is the nucleic acid responsible for containing, copying and transferring genetic information to an organism’s offspring (Bailey).

All these organic compounds are very important.  None are more important than the other.  Knowing what you know now, be sure to eat healthy because three of the five compounds are found in the diet.  The other two are just as important because they have essential roles in the human body.  Without any one of these compounds, the human body would not be able to survive.
