Compounds that have the same chemical formulas but different chemical structures are also isobars and might therefore be referred to as strict isobars because they have exactly the same mass. Succinic acid and methylmalonic acid provide an example of a pair of compounds that are strict isobars be...
Using the self-made epoxysuccinic acid as raw material,polyepoxysuccinic acid(PESA)was synthesized in virtue of anionic polymerization.In addition,the expected product was characterized by means of IR.and the six factors influencing relative molecular weight and yield of PESA were investigatd,as a ...
To develop and evaluate the novel renal drug carrier, prednisolone, used as a model drug, was covalently coupled with various molecular weight LMWCs via a succinic acid spacer. The mean residence time (MRT) in plasma of prednisolone conjugates increased as the molecular weight increased. The ...
