... SMTP-1 differs from the above metalloporphyrin-based structures. The metal cation in the center of the porphyrin ring is also coordinated to pyridyl groups of other tpp complexes, allowing the ... both SAPO’s and MeAPSO’s. However, the thermal stability of MeAPO’s is generally lower than that of either AlPO 4 ’s or SAPO’s. In general, the thermal stability of a me...

... formed. The protein is then precipi- tated from the solution. The pH at which this happens is called the isoelec- tric point of the protein. In the presence of an excess of hydrogen ions the molecules ... calcium orthophosphate, which impairs the cheesemaking properties of the milk. The degree of heat treat- ment must be carefully chosen. Physical properties of...
