Final answer:
Insulin zinc suspension (Lente) is an intermediate-acting insulin used in the treatment of diabetes, consisting of insulin combined with zinc to extend the duration of action for maintaining steady blood sugar levels.
Step-by-step explanation:
Insulin zinc suspension (Lente) is a type of intermediate-acting insulin used in the management of diabetes mellitus. Insulin is a critical hormone for the regulation of blood glucose levels. It consists of two polypeptide chains; chain ‘A’ with 21 amino acids and chain ‘B’ with 30 amino acids, totaling a molecular weight of 5734 Da. The “Lente” formulation refers to a preparation where the insulin is combined with zinc in a specific suspension which affects how the insulin is released into the bloodstream. This helps in extending the duration of its action, providing a steadier level of blood sugar control over a longer period.
Typically, when administered, the onset of action for Lente insulin is several hours after injection and it has a relatively longer duration of action when compared to short-acting insulin. This makes it useful in maintaining basal levels of insulin in the body and is often administered once or twice daily. The precise timing and dosage depend on the needs of the individual and should be determined by a healthcare professional.
