Human monocomponent insulin. Chemistry and characteristics.

Abstract

The primary structure of different insulins is reviewed and the properties, identification tests, purity, potency and immunogenicity of human insulin are summerized. Novo Research Institute has developed a method, simply using an enzymatic conversion reaction to substitute the B30 alanine of porcine insulin with threonine to manufacture human insulin. This process is basically an extension of the process currently used to manufacture the Novo purified insulins which are commercially available.
