Insulin comes in various concentrations. 40U insulin means that there are 40U (or "units") of insulin in 1ml while 100U insulin means that there are 100 units of insulin in 1ml.
It should also be noted that insulin syringes come calibrated to the type of insulin they are to be used with, so you should never use a 40U syringe with 100U insulin, for example, without consulting your doctor for the correct dose with the mismatched syringe.

How do substances work by altering the ways cells function?
Like the receptors for other protein hormones, the receptor for insulin is embedded in the plasma membrane. The insulin receptor is composed of two alpha subunits and two beta subunits linked by disulfide bonds. The alpha chains are entirely extracellular and house insulin binding domains, while the linked beta chains penetrate through the plasma membrane. The insulin receptor is a tyrosine kinase. In other words, it functions as an enzyme that transfers phosphate groups from ATP to tyrosine residues on intracellular target proteins. Binding of insulin to the alpha subunits causes the beta subunits to phosphorylate themselves (autophosphorylation), thus activating the catalytic activity of the receptor. The activated receptor then phosphorylates a number of intracellular proteins, which in turn alters their activity, thereby generating a biological response. Several intracellular proteins have been identified as phosphorylation substrates for the insulin receptor, the best-studied of which is insulin receptor substrate 1 or IRS-1. When IRS-1 is activated by phosphorylation, a lot of things happen. Among other things, IRS-1 serves as a type of docking center for recruitment and activation of other enzymes that ultimately mediate insulin's effects. from yo mama
What are the 4 kinds of subunit?
The four kinds of subunits are: alpha subunits, beta subunits, gamma subunits, and delta subunits. These subunits play a crucial role in forming the structure and function of various macromolecules in biological systems, such as proteins or nucleic acids.
What are the subunits polysaccharides?
The subunits of Polysaccharides are monosaccharides
What is the fate of the newly formed subunits?

Subunits in carbohydrates?
The subunits (or monomers) of carbohydrates are monosaccharides and disaccharides. The polymers (the products of these linked subunits) are starches and polysaccharides.
How many different kinds of protein subunits are there?
1000's of proteins subunits can be made.
What subunits make up nucleic acids?
The subunits making up nucleic acids are nucleotides

the number of histone subunits in a nucleosome is?
What are the subunits?
For example glucose.
What subunits are present in carbohydrates?
Carbohydrates, Cx(H2O)y, are made up of two subunits, carbon (Cx) and water (H2O)y, where x and y are the number of molecules in each of the subunits.
