Hertz. Hertz (abbreviated: Hz) is the standard unit of measurement used for measuring frequency. Since frequency is measured in cycles per second, one hertz equals one cycle per second. Hertz is used commonly used to measure wave frequencies, such as sound waves, light waves, and radio waves.
Novolin R should only be mixed as directed by the physician. 1  Novolin R is a short-acting insulin and is often used in combination with intermediate- or long-acting insulins. 2  The order of mixing and brand or model of syringe should be specified by the physician.

One rapid-acting insulin analog is insulin lispro, which is marketed by Eli Lilly and Company as Humalog and became commercially available in 1996. The structure of the insulin lispro molecule is identical to that of human insulin except that the amino acids at two positions on the B chain, B28 and B29, are reversed.nsulin is a hormone, or chemical messenger that is released into the bloodstream to be transported throughout the body. Most hormones, including insulin, are proteins, which means that they are made up of molecules called amino acids.
