Harris-Benedict Tables

Harris-Benedict Tables is a method that is used to determine the composition and structure of molecules in chemistry and biology. This method was developed by John Albert Harris and Francis Howard Benedict in 1935.

Harris and Benedict proposed a method based on the use of tables in which the values ​​of the relative atomic masses and electronegativity of the elements were indicated. This method allows one to determine the composition and structure of a molecule, as well as its properties.

Harris-Benedict table method is one of the most common methods in chemistry and biochemistry. It is used for the analysis of proteins, nucleic acids, lipids and other molecules. The method can also be used to determine the structure and properties of molecules, as well as to study their interactions with other molecules.

In conclusion, it can be said that the Harris-Benedict table method is an important tool in the field of chemistry and biochemistry, which allows scientists to study the structure and properties of molecules.

Harris-Benedict Tables are an important discovery in the field of chemistry and biology, created by John Addison Harris (J. A. Harris) and Francis George Benedict (F. G. Benedict) in 1935. Harris and Benedict were American biochemists and physiologists who worked to develop methods for studying the biochemical properties of proteins.

Harris and Benedict conducted experiments studying the effect of temperature on the rate of chemical reactions. They noticed that for each protein there is a certain temperature at which the reaction rate is maximum. This temperature is called the optimum temperature or optimum melting point.

Instead of trying to find the optimal temperature for each protein separately, Harris and Bededict developed a table that could predict that temperature for all proteins simultaneously. In this table they used the temperature coefficient, which is a measure of the effect of temperature on the rate of a chemical reaction.

The temperature coefficient is calculated as follows: it is necessary to raise the temperature to a power equal to the coefficient in the list and multiply by the value of the rate constant. A rate constant is a mathematical quantity that describes the rate of a chemical reaction under conditions without additional reagents or catalyst.
