Be. Insulin is a protein hormone secreted by islet cells in the pancreas.
Insulin is involved in regulating carbohydrate and fat metabolism, controlling blood sugar balance, and prompting the liver and skeletal muscles to convert glucose in the blood into glycogen. Lack of effective insulin can lead to high blood sugar, diabetes. Therefore, insulin can be used for diabetes.
Its molecular weight is 5808 daltons.
Insulin has been used in clinical practice for decades, from the first generation of animal insulin with strong antigenicity to the second generation of human insulin that is genetically recombinant but needs to wait 30 minutes before a meal, and then to the current insulin analogues that can well mimic the physiological pattern of human insulin secretion. At present, insulin that better mimics the physiological hypoglycemic pattern of normal human beings is the third-generation insulin, an insulin analogue.

Bovine insulin is, of course, protein.
The basic units that make up proteins are amino acids, which form peptide chains through dehydration and condensation. Protein is a biological macromolecule composed of one or more polypeptide chains, each of which has 200 or more amino acid residues. The various amino acid residues are arranged in a certain order.
Bovine insulin: Extracted from bovine pancreas, the molecular structure has three amino acids, ok, obvious.
-
Do you want to ask if it's protein, or do you want to ask if it's not protein?
Whatever you ask, bovine insulin is a protein, and it was the first protein molecule to be measured in primary structure.
You can take a look.
-
Bovine insulin is a protein, and you say that bovine insulin is not a protein in the textbook, either you read it wrong, or you printed it wrong, or you made a mistake when you typed the question. Bovine insulin is made up of 223 amino acids, how is it not protein?

Bovine insulin is, of course, protein.

Insulin is a protein-like hormone. Insulin in the body is secreted by pancreatic islet cells.
Here's a more detailed explanation:
1.Next to the duodenum of the human body, there is a long organ called the orange pancreas.
2.There are many groups of cells scattered in the pancreas called islets.
3.The total number of islets in the pancreas is about 100.2 million. Pancreatic islet cells are divided into the following types according to their function of secreting hormone: (learned in high school biology class).
B cells ( cells), which make up about 60% to 80% of islet cells, secrete insulin, which lowers blood sugar.
A cells ( cells), which account for about 24% to 40% of islet cells, secrete glucagon, which acts in the opposite way to insulin and can increase blood sugar.
D cells, which account for about 6% to 15% of the total number of islet cells, secrete growth hormone inhibitory hormone.

Insulin is a protein. So it can't be taken orally, only injected. The stomach breaks down proteins.
Protein hormones secreted by the islets of Langerhans in the pancreas. It is composed of A and B chains and contains a total of 51 amino acid residues. It can enhance the uptake and utilization of glucose by cells, and promote the synthesis of protein and lipid metabolism.
-
Insulin is a protein that contains 51 amino acids.
-
It should be, it is a protein hormone for details.
-
It is protein, and all the insulin produced by animals is protein, which is made up of peptide chains formed by amino acids. Human insulin is made up of two peptide chains formed by 51 amino acids.
-
A: Insulin is a hormone secreted by pancreatic B cells, a protein composed of 51 amino acids and two peptide chains. It is functional to lower blood sugar concentrations. If insulin secretion is insufficient, the oxidation pathway of sugar is blocked, which can lead to diabetes.
-
The insulin molecule also has two peptide chains, which are protein molecules containing 52 amino acids.
-
I guess it will be digested directly if you swallow insulin directly
-
It is not a protein, it can only be regarded as a polypeptide chain, because it does not have the spatial structure of proteins, and insulin mainly controls blood sugar and has an antagonistic relationship with glucagon.
-
The insulin molecule has two peptide chains and contains 52 amino acids. Generally speaking, more than 50 amino acids are considered proteins, and of course they must have a certain spatial structure and function, as insulin has.
-
It's protein, I've confirmed the teacher. Insulin is a hormone secreted by pancreatic B cells that regulates the lowering of blood sugar. Insulin is two peptide chains of 51 amino acids that are coiled to form proteins with a three-dimensional structure.
Whereas, glucagon is a straight peptide chain composed of 29 amino acids.
That's all, I hope it can help you.
-
Yes, because of this, it can only be injected with **diabetes.
It is a meaning, but the translation is different, English incretin, there are translations of incretin in China, some are translated as incretin, some are translated as incretin, and some are translated as incretin, in fact, I personally prefer the translation of incretin, because this kind of hormone is secreted by the intestine and has a blood sugar regulating effect, but its role is not only to promote the secretion of insulin, but also to inhibit glucagon secretion, reduce appetite, control weight, etc., these combined effects all help to lower blood sugar.
If you have type 1 diabetes, you will definitely not get it if you don't get it. It's going to die. If you have type 2 diabetes, you can use oral medication to control it.
