In most chemical analysis for determination of a given compounds, protocol is usually, recommended a given pH if we do not confined to this pH we will not accomplished the desired reaction precisely at least..... are there interpretations
Metabolic reactions are driven by specific enzymes, which are proteins. Proteins are polimers of amino acids which can be ionized or not depending of the pH. The 3D structure of a protein is related to its activity. Changing the ionization of amino acids of an enzyme by pH modification, you can modify activity of enzymes, therefore affecting metabolic reactions...

Dear Gustavo Felippe da Silva Esq.
This is true in some bio-reactions. However, there are to many chemical reactions in inorganic and organic chemistry required given pH, but devoid of enzyme involvements.
The biological availability of key plant nutrients are optimized at fairly narrow pH ranges. In relationship to this Phosphorus comes to mind. at acid pH the Phosphorus availability is compromised by Iron, Aluminum, Manganese, and Calcium. The window of peak Phosphorus availability is 5.7 to 6.7 pH and outside that range the ability to get Phosphorus in solution will limit the metabolism based on deficiency.
pH is obviously related to the presence of H+ ions which are involved in many biological and a biological reactions. Also remember the pH scale is logarithmic so each pH change of a unit representa a 10-fold change in H+ concentration.
Dear Colludes Esq.
With pH ionic bonds can be weaken and/or strengthen depends upon the ionic bond connected two compound. Weakening and strengthening ionic bonds allows the substitution of compound with another one to facilitate the production of newly required product. Thanks for all...... It is also somehow related to enzyme or amino acid Isoelectric points this true in vitro not in vivo, since pH are burred in cytoplasm
First and fore most because of involvement of amino acids(as the case of enzymes), protonated and deprotonated forms of amino acids facilitate the reactions. Secondly, if no amino acids,with pH ionic bonds can be weaken and/or strengthen depends upon the ionic bond connected two compound. Weakening and strengthening ionic bonds allows the substitution of compound with another one to facilitate the production of newly required product.
