Dear Collegues,

A compound contains the following substances with the
corresponding functions :

1) Malic acid ( Function : organic acid catalyst)
2) Sodium Hexametaphosphate (Function : Inorganic
   buffering agent)

      MALIC ACID CITRIC ACID

         COOH CH2-COOH
      HO-C-H HO-C-COOH
         CH2 CH2-COOH
         COOH

- Can Malic acid be substituted by Citric acid for
this purpose as an organic acid catalyst ?
Citric acid is very similar in structure to Malic acid
Both are metabolites in Krebs/Citric acid cycle

- Can Sod.Hexametaphosphate be substituted by sodium
citrate as the buffering agent ?
Citric acid/Sodium Citrate buffer

Aim is to achieve dual purpose of citric acid : As an
organic acid catalyst and buffering agent.
Is this possible?

Thanks in advance,
jmarjorie
