Is insulin or glucose bigger?
An insulin molecule is much bigger than a glucose molecule.
What is the hydrophobic or hydrophilic areas of insulin?
Insulin core is hydrophobic but its periphery has hydrophillic regions
Which pancreatic hormone stimulates the uptake of glucose by cells?
The hormone that predominately signals glucose uptake by the cells is the insulin. It is secreted in the pancreas by the islets of Langerhans.
Is insulin a quaternary or tertiary structure?
Insulin has a tertiary structure which is folded into a spherical shape. An insulin molecule comprises two chains of amino acids held together by disulfide bonds. This is the active state of the hormone.
What is the difference between insulin and hemoglobin?
The only thing that they have in common is that they are proteins. Insulin is a molecule that carries glucose across the body cell membranes. Hemoglobin is a very large molecule that contains iron and carries oxygen. The red blood cells are packed with it.
What is the name of the molecule that is proein hormone that tells animal cells to store blood glucose as glycogen?
Insulin
The bonds that hold the two chains of an insulin molecule together are?
s-s bridge or disulfide bond
What would happen to a insulin molecule if the amino acids were assembled in a different order?
It wouldn't work right.
How many amino acid residues are in an insulin molecule?
Human insulin (I'm not sure about other species) is a 51-residue peptide. It's stored as a hexamer, but the active form is the monomer.
Does an organic molecule contain sulfur?
It can do!!!! If you take the molecule ethanol (ethyl alchol) CH3CH2OH , and substitute the the oxygen for sulphur, we have CH3CH2SH. This molecule is 'ethanethiol'. A critical biologicial molecule that contains sulphur is 'Insulin'. needed by humans to control sugar levels in the blood stream.
How does insulin open pores?
Once in the blood, insulin molecules can reach all the cells of the body. An insulin molecule is able to attach itself to the cell membrane of cells. When it does, one kind of pore opens. Sugar from the blood can then enter the cell through the open pore.
Which molecule from humans is inserted into bacteria to cause them to produce insulin?
No. When genes from humans are inserted into bacteria, the bacteria acts as factories that produce chemicals of importance to humans, such as insulin.
