What is the difference between calyx cell recognition and cell recognition of membrane proteins

The main difference between the two is the different ingredients.

The proteins contained in biofilms are called membrane proteins, which are the main bearers of biofilm functions. According to the difficulty of protein separation and the location of distribution in the membrane, membrane proteins can be basically divided into three categories: outer membrane proteins or peripheral membrane proteins, inner membrane proteins or integral membrane proteins, and lipid-anchored proteins.

Membrane proteins include glycoproteins, carrier proteins, and enzymes, among others. Usually there are sugars attached to the membrane proteins, which are equivalent to transmitting signals to the cell through changes in the molecular structure of the sugar itself.

Glycocalyx is a general term for the viscous substance secreted by bacteria, epithelial cells, or other cells that covers the surface of cells. The mucus from the skin of fish is a kind of sugar calyx. The original meaning of this term refers to the polysaccharide structure that covers the surface of epithelial tissue and is secreted by epithelial cells.

The structure between the capsular and mucus layers is called a glycocalyx. Glycocalyx is a general term for a polysaccharide protein complex that covers the surface of the apical membrane of vascular endothelial cells. It is connected to endothelial cells by a number of backbone pillars, which include proteoglycans and glycoproteins.

The interaction between the two forms a network in which some plasma-derived and endothelial-derived soluble biomolecules are incorporated into this network to form the basic structure of the glycocalyx. Soluble plasma components are directly or indirectly linked (via proteoglycans and mucopolysaccharides). There is a dynamic equilibrium between the soluble components of the glycocalyx and the plasma, which continuously affects the composition and thickness of the glycocalyx, while the glycocalyx is constantly shedding under the action of enzymes and shear forces, and at the same time a new dynamic equilibrium is generated and shed.

Cell-to-cell recognition involves signaling through selective interactions with other cell surface ligands or receptors through cell surface receptors or ligands, resulting in a range of physiological and biochemical responses. Regardless of the identification system, they all have a common basic characteristic, that is, selectivity, or specificity.

1. Material transportation, mainly involved in assisted diffusion, active transportation, ion channel transportation and other modes of transportation;

2. Information recognition, such as blood group matching and fertilization, is related to the recognition of membrane proteins;

3. Protective functions, such as glycoproteins on the surface of the membrane;

4. Lubrication, such as glycoprotein on the surface of the membrane.

To be precise, a glycoprotein is also a protein.

Glycoproteins are on the surface of the cell membrane and are responsible for cell recognition.

Glycoproteins made up of sugars and proteins are related to cell recognition!

Glycoprotein... But glycoprotein = carbohydrate + protein.

Cell-to-cell recognition is related to the cell's cancerous glycoproteins (proteins and carbohydrate composition).

There are three types of membrane proteins: mosaic, intercalated, and transverse components are proteins.

It's good, there is carcinogenesis first, and then the membrane changes, and people have membrane changes, and protein doesn't play any role.

Satisfactory Answer: Voluntary Fugitive, Level 142011-07-23It has a very important function in cellular life activities. For example, glycoproteins in the epidermis of the digestive and respiratory tracts have a protective and lubricating effect; Sugars are closely related to cell surface recognition. The sugar on the surface of the cell membrane of cancer cells is reduced, the adhesion is reduced, and it is easy to spread and metastasize.

Blood group determination on the red blood cell membrane. Follow-up question: Is sugar determined by blood type on the red blood cell membrane?

General protein refers to a multimer composed of amino acids, which has structural, catalytic, transport, regulatory and immune functions; Glycoproteins, on the other hand, are formed by the organic combination of proteins and sugars, mainly for the function of recognizing and transmitting information, such as receptor proteins; As for membrane proteins, they generally refer to proteins on cell membranes, including glycoproteins.

The most essential difference is the spatial structure.

Glycoprotein is on top of the protein, which is made up of some filaments on a circle, that is the glycoprotein.

There is a difference between biology and the teacher said.

Cellular recognition is related to glycoproteins, which are made up of proteins and polysaccharides. So cellular recognition is not only related to the proteins in the glycoproteins, but also to the sugar chains.

I think so, the key difference between glycoproteins is amino acid sorting, and this different ordering will have different recognition functions. Just like immunoglobulin, it has a special recognition function to eliminate "foreign bodies".

Sugars are divided into monosaccharides, disaccharides and polysaccharides, monosaccharides include glucose, fructose, ribose, deoxyribose, etc., disaccharides include sucrose, maltose, lactose, etc., and polysaccharides include starch, cellulose and glycogen.

Sugars are the most abundant compounds in the dry weight of most plants.

1. The concept is different

Glycoproteins are substances on the surface of the cell membrane that are linked together by the sugar chains and proteins on the cell membrane.

Glycocoat is a general term for glycolipids and glycoproteins. Glycolipids are formed by the combination of sugar chains and lipids.

2. Glycoprotein is the structure, and the glycoprotein is the tissue.

3. Different ingredients:

Glycoprotein is a sugar-containing protein, and the composition of the glycocoat is generally polysaccharides, a few are proteins or polypeptides, and there are also polysaccharides and polypeptide complex types.

On the surface of the cell membrane, there is a layer of glycoproteins called glycoproteins formed by the proteins on the cell membrane and polysaccharides.

Essentially, sugar refers to the real structure of matter that has a physiological function, that is, the thing that has a recognition function.

And glycoprotein is the chemical essence of that thing that recognizes! It's the ingredients!

Good luck in your studies1

Glycoprotein refers to a protein embedded in phospholipids that is attached to a sugar chain, sugar refers to a structure that surrounds the cell membrane and is composed of a variety of substances, and sugar refers to the glycoprotein on the cell membrane.

A glycoprotein is a protein that contains oligosaccharide chains, which are linked by covalent bonds. The oligosaccharide chains are usually linked to proteins through glycosylation during co-translation modification or post-translation modification.

In glycoproteins, the composition of sugars is often complex, including mannose, galactose, fucose, glucosamine, galactosamine, sialic acid, etc.

Glycoprotein polypeptide chains often carry many short heterosaccharide chains. They usually include N-acetylhexylfurfuramine and hexose (often galactose and/or mannose, but less glucose).

On the surface of the cell membrane, there is a layer of glycoprotein formed by the combination of proteins and polysaccharides on the cell membrane, which is called glycocoat.

Glycoproteins on the surface of epithelial cells of the digestive and respiratory tracts have protective and lubricating effects; Sugars are closely related to cell surface recognition.

The recognition of glycoproteins on the surface of animal cells is like the words or language used to communicate between cells, or between cells and other macromolecules.

That's all I can tell you, maybe it's one side of the glycoprotein side of the story! Hope it helps you a bit

Glycoprotein has a lot to do with immunity It has a special function of recognizing certain antigens and is located outside the cell (like a detector).

It is located on the phospholipid bilayer. Proteins that play a role in recognition.

A bound protein in which the non-protein part is a carbohydrate substance and is covalently bonded to the protein moiety, and the attached sugar is either a monosaccharide or a relatively short oligosaccharide. Usually each molecule contains less sugar (about 4%). Some glycoproteins contain only one or a few glycans, while others contain multiple linear or branched oligosaccharide side chains.

Glycoproteins are usually secreted either into body fluids or into membrane proteins, which are located outside the cell and have corresponding functions. Glycoproteins include enzymes, hormones, carriers, lectins, antibodies, etc.
