The PH scale is numeric and always indicates the levels of hydrogen ions in a solution or a substance. It is used to ascertain the acidity or the basicity level of a substance. The level of acidity is always expected to have a lower PH value than all the basic substances. The PH scale plays a crucial role in the health of a person as it helps determine the body’s PH balance (Costa & Fernandes, 2018). The acid-base balance in the body is crucial as it helps the body to be able to function properly. The human body is made to maintain a healthy balance of the acidity and base, and any time the levels go up or down, different problems arise in the body. Acids and bases are responsible for balancing the body’s PH levels, and they also help break down some components to be in ways that the body can easily use them. Salts are essential in balancing the PH of a solution. A buffer is a solution made up of a weak acid and its salt or a weak base and its salt. The buffer solution is always used to neutralize a strong base or acid as it can resist PH change when it gets into contact with an acid or base substance, and this helps in making the PH levels stable.
Carbohydrates, lipids, proteins, and nucleic acids are important human structures and functions. The carbohydrates contained three elements, Carbon, Hydrogen and Oxygen, and their major function is to provide energy to all living things (Sarbu et al., 2017). Proteins structures contain Carbon, Hydrogen, Oxygen, Nitrogen and Sulphur, and they are essential in providing structures in the body. Lipids structures have Carbon, Hydrogen and Oxygen but they are different from carbohydrates as they are fats and oils, and their function is to store energy in the body. The Nucleic acids structures are made of Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorus, and their function is to create and store biological information in the cells.
