What Does pH Balanced Digestive Enzymes Mean?

By

The Chemistry: pH

The measurement of pH is actually a measurement of hydronium ions in a particular solution. By measuring the presence of these particular ions, it is possible to determine whether the solution is acidic or alkaline. The typical pH range is from 0-14. Neutral compounds are located around a pH of 7. Acidic solutions have lower pH's, while alkaline solutions have higher pH's. The closer the substance pH is to zero, the more acidic, and vice versa holds true, the closer the pH is to 14, the more alkaline (basic) the solution is.

Examples of pH

All fluid substances have a pH value.It is also possible to dissolve certain substances to obtain pH values. This is commonly utilized in a laboratory setting. The following is a list of substances commonly known, and their associated pH values.

  • Sodium hydroxide (1 Molar): 14.0
  • Ammonia: 12.0
  • Drano: 11.9
  • Milk of Magnesia: 10.5
  • Toothpaste: 9.9
  • Baking Soda: 9.1
  • Egg Whites: 8.0
  • Water: 7.0
  • Milk: 6.0
  • Tomato Juice: 4.1
  • Vinegar: 2.4
  • Lemon Juice: 2.2
  • Hydrochloric Acid: 0.0

The Body and pH Importance

The body must regulate pH. Provided is a list of some body fluids and their associated pH. The gastric acid (hydrochloric acid) of the stomach obviously has a very acidic pH, at approximately 1.0. Blood plasma is slightly alkaline, maintained at approximately 7.4. Water typically ranges between 6.8 and 7.2, dependent upon the type and the amount of other materials it includes. The lysosome, which is responsible for the destruction of certain foreign substances, maintains a pH of approximately 5.5, slightly acidic. Urine is also slightly acidic, with an average pH value of 6.4.

Digestive Enzymes and pH

Most digestive enzymes require a proper environment for the assurance of correct functioning. The pH of the environment is commonly used as a regulatory factor. Each enzyme in the body has a pH preference. These preferences are dependent upon the enzyme. The activation of enzymatic properties is a complicated topic that is currently researched in a variety of laboratory settings.The pH value is very important to all biological systems throughout the body. The pH is capable of changing the shape and overall charge of enzymes. Many enzymes must be charged to perform their enzymatic functions.

  • Pepsin: 1.5
  • Lipase: 4.0-5.0
  • Maltase: 6.0-6.8
  • Amylase (pancreas): 6.7-7.0
  • Amylase (malt): 4.6-5.2

Energy and pH

Every single reaction mechanism in the body comes down to the need for energy. The majority of energy throughout the body is stored as potential energy and utilized as kinetic energy. This storage of energy is typically accomplished through the formation of specific bonds. It is the breaking of these bonds that cause an energy release. The body must maintain an optimum pH for cellular activity to ensure that energy is stored and released. The presence of hydronium ions is necessary for nearly all reactions within the body.
