Insulin is a hormone manufactured by B-cells in the Pancreas.

Pancreas
Trigger body cells to take up glucose.
Human insulin is preferable to animal insulin because it is made through genetic engineering, ensuring higher purity and reducing the risk of allergic reactions. Additionally, human insulin closely mimics the natural insulin produced by the human body, which leads to more predictable and consistent results in managing diabetes. Lastly, human insulin is now more widely available and cost-effective compared to animal-derived insulin.
The pancrease
Sugar in the blood.
The pancreas secretes digestive enzymes along with the enzymes insulin and glucagon.
Insulin is most definitely a biological substance. It is produced in the body and is made up of carbon and hydrogen atoms.
The insulin that we engineer bacteria to make (E.colidoes not naturally make insulin) is identical to human insulin.
Human Insulin, is a replica of the insulin found naturally in human beings. These are synthetically prepared. An insulin analogue however is an altered form of this human insulin, by addition,subsitution or substraction of one/or more amino acid chain/s. This is done to make insulin more safe and effective for human use.
The process involves inserting the human gene for insulin into a bacterial plasmid, which acts as a vector. The bacteria then replicates the gene and produces insulin protein. The protein is harvested, purified, and formulated into insulin for medical use.
Pig insulin is used as a substitute for human insulin in some cases because it is similar in structure and function to human insulin, making it effective in managing diabetes. Additionally, using pig insulin can be more cost-effective and readily available for some patients compared to human insulin.
