The food we consume can either be beneficial or not depending on the body’s requirements. However, the required components by the body are usually absorbed and utilized or stored as reserves for later use. Additionally, the excess and undigested matter that is ingested is expelled as fecal matter. This means that we should always be mindful of our dietary intake. The biomolecules topic has broadened my view on the function of each of the components and why we need to include them in our diet. Since we utilize energy in all our actions even while sleeping, carbohydrates should be our primary energy source and should be included in our meals. People who frequently do intense work like miners, manual laborers, and athletes should frequently take in carbohydrates. This is because carbohydrates are easily broken down during metabolic processes to provide energy as compared to the other biomolecules.
Proteins are also essential when selecting the foods to eat since they act as building blocks for cells and body systems. Proteins are required for growth and development as well as in the replenishing of enzymes that control metabolic reactions. Proteins ingested are usually broken down in our body into amino acids and depending on their need, they are utilized by the body. Our dietary intake should also include nucleic acids since they play a significant role in DNA and RNA formation. Cellular replication and protein formation through translation often require nucleic materials. Nucleotides are the building blocks of nucleic acids and they help in the storage and transfer of genetic information which happens not only during replication but in gamete formation. Additionally, other energy-forming components like ADP contain nucleic acid.
The body also has its unique way of storing energy reserves which are in form of lipids. The building blocks of lipids are glycerol and fatty acids and these are produced from the excess carbohydrates in the body. Our dietary intake should not include a lot of lipids since they are quite difficult to break down (since they are not water-soluble) by fat-digesting enzymes in the gastrointestinal tract. However, the little lipids that we ingest can be utilized in cell membrane formation. Generally, our diet should include all the biomolecules but more of the carbohydrates and less of lipids since all are necessary to our body development and operation.
