Insulin lispro is a rapid-acting insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli . Insulin lispro differs from human insulin in that the amino acid proline at position B28 is replaced by lysine and the lysine in position B29 is replaced by proline. Chemically, it is Lys(B28), Pro(B29) human insulin analog and has the empirical formula C 257 H 383 N 65 O 77 S 6 and a molecular weight of 5.808 kDa, both identical to that of human insulin. Humalog Mix50/50 (insulin lispro protamine and insulin lispro) injectable suspension is a mixture of 50% insulin lispro protamine, an intermediate-acting human insulin analog, and 50% insulin lispro, a rapid-acting human insulin analog. Insulin lispro protamine suspension is a suspension of crystals produced from combining insulin lispro and protamine sulfate under appropriate conditions for crystal formation. Insulin lispro has the following primary structure: HUMALOG Mix50/50 (insulin lispro protamine and insulin lispro) injectable suspension is a sterile, white and cloudy suspension for subcutaneous use. Each mL of HUMALOG Mix50/50 contains 100 units of insulin lispro; dibasic sodium phosphate (2.0 mg), glycerin (16 mg), metacresol (2.20 mg), phenol (0.89 mg), protamine sulfate (0.19 mg), zinc oxide content adjusted to provide zinc ion (0.0305 mg), and Water for Injection, USP. The pH is 7.0 to 7.8. Sodium hydroxide and/or hydrochloric acid is added during manufacture to adjust the pH. Primary Structure
