What class of molecules contain the group NH2?
PROTEINS
What molecules are found in soil?
soil
Is citric acid a class II preservative?
yes it is....
How many atoms of iron are found in 2 molecules of iron sulfate?
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
What term describes the class of molecules that includes starch and glycogen?
carbohydrates
What is the major class of organic molecules found in egg yolk?
major class of molecules found in egg yolk
Class II MHC molecules are found only on which of the following?
Presented by APCs as MHC-exogenous peptide complex
What is the difference between a class I MHC mechanism vs a class II MHC mechanism?
The Class I MHC molecules process endogenous(intracellular) peptides/antigens whereas the Class II process exogenous(extracellular) peptides/antigens. The Class I molecules are assembled and located in the ER whereas the Class II are assembled in the ER but located in the endosomes. When extracellular peptides are taken into the cell via receptor mediated endocytosis or phagocytosis, they will be transported into the endosomes and get degraded. This will enable the peptide generated to be loaded onto the Class II molecules. For Class I, when a bacteria or virus infect a cell, they will replicate and produce proteins. These proteins will be ubiquitinated and degraded by the proteasome. This smaller peptides can then be transported into the ER via the TAP transporters, that are complexed with the Class I molecules, to be loaded onto the Class I molecules.
Is HLA only found on leukocytes?
HLA (human leukocyte antigen) is the name for the MHC (major histocompatibility complex) found in humans. MHC class I molecules (HLA-A, HLA-B, HLA-C) are found on pretty much all cells (some important exceptions are red blood cells). MHC Class II molecules (HLA-DQ, HLA-DP, HLA-DR) are found on special antigen presenting cells, which include B-lymphocytes, dentritic cells, and macrophages.
What is the type of major histocompatibility marker that's most likely found on a liver cell?
Answer Class II MHC protein. Class II are found in membranes of antigen-presenting cells-phagocytic cells and lymphocytes. The liver performs phagocytosis and antigen presentation.
What role does the macrophage play in?
presents antigens of an engulfed pathogen in its class II MHC molecules to helper T cells, and releases IL-1
How many water molecules are bound to iron II ammonium sulfate?
Six water molecules are bound to iron (II) ammonium sulfate.
When was DRG Kleinlokomotive Class II created?
DRG Kleinlokomotive Class II was created in 1932.
What molecules are found in chromosomes?
DNA molecules.
Can a Class II ball mount can be used with a Class III receiver hitch.?
No ... the ball diameter (and subsequent nut and fitting) are smaller on Class II.
Can a Class II ball mount be used with a Class III receiver hitch?
No ... the ball diameter (and subsequent nut and fitting) are smaller on Class II.
Is Xanax a Class II Narcotic?
