What do glycoproteins have that simple proteins do not?
Glycoproteins have a carbohydrate, glycogen, attached to them. They face the outside of a cell, and are vital for certain functions, such as cell to cell recognition.
The ER sends proteins and lipids it makes to what to be modified?
The endoplasmic reticulum (ER) sends proteins and lipids in membranous vesicles to the Golgi body (also known as the Golgi apparatus or the Golgi complex). The Golgi body looks like a stack of pita breads; it resembles the ER. There, the membranous vesicles containing proteins or lipids will fuse with one side of the Golgi body known as the cis face.Inside the Golgi body, proteins and lipids will have carbohydrate molecules added to them, forming glycoproteins (proteins with carbohydrates attached) and glycolipids (lipids with carbohydrates attached). After being modified, the glycoproteins and glycolipids will exit the Golgi body in membranous vesicles through the trans face (the side opposite the cisface).
How do you use Attached in a sentence?
Excuse me, miss, are you currently attached? My hand is attached to a chair. Please see the attached example. I have attached the power cord plug to the wall socket.
What are the changes in width of attached gingiva with age?
Width of attached gingiva increases with age.
Is your hair an inanimate object?
If your hair is attached to you and you are an animate object than no but if your hair was not attached to you (fell out) than I guess it would be inanimate. :)
Proteins with sugar molecules attached to them are called what?
glycoproteins
What are glycolipids and glycoproteins?
Glycolipids are lipids with a carbohydrate attached. While glycoproteins are proteins that contain oligosaccharide chains covalently attached to polypeptide side-chains.
What are proteins with surgar molecules attached to them called?
I believe they are called glycoproteins
What do glycoproteins have that simple proteins do not?
Glycoproteins have a carbohydrate, glycogen, attached to them. They face the outside of a cell, and are vital for certain functions, such as cell to cell recognition.
What name is given to proteins with sugars attached?
carbohydrates are short polysaccharides composed od different
What part of the body do the glycolipids and glycoproteins identify self and nonself?
Glycoproteins are proteins covalently attached to carbohydrates Glycolipids are lipids attached to carbohydrates. The antigen that determines blood types belongs to glycoproteins and glycolipids.
What are proteins with suger molecules allached to them called?
Proteins with saccharides (sugar molecules) attached to them are known as glycoproteins.
What is the important function of oligosaccharides in plasma membranes?
Enable cell recogination and attached to globular protein to form glycoproteins
The molecule that make the cell surface fuzzy sticky and sugar-rich are the?
Glycoproteins and glycolipids are the molecules that make the cell surface fuzzy, sticky, and sugar-rich. They have carbohydrate chains attached to proteins and lipids, respectively, creating a glycocalyx that helps with cell-cell recognition and adhesion.
What is a glycoprotein?
Glycoproteins are proteins that contain oligochakarid chains (glycans) covalently attached to polypeptide side-chains. The carbohydrate is attached to the protein in a cotranslational.
Can glycoproteins be lipids associated with carbohydrates?
Glycoproteins are not lipids but rather proteins that have carbohydrate groups attached to them. These carbohydrates can be linked to the protein through covalent bonds, influencing the protein's function, stability, and localization. While glycoproteins themselves are not lipids, they can be found in lipid-rich environments, such as cell membranes, where they may interact with lipids and other biomolecules.
What is the difference in the function of the protein and the carbohydrate attached to a cell membrane?
--------------------------------------- Many of the proteins in a cell membrane actually have carbohydrates attached to them as they are secreted through the endoplasmic reticulum and Golgi apparatus, and these are called glycoproteins. It's hard to generalize the function of glycoproteins since they are involved in really diverse processes such as cell signaling, development, immune response, sperm-egg recognition, virus-host cell interactions etc and can also play important roles in making sure a protein folds correctly so it can function. It's important to note that glycoproteins can interact with other glycoproteins or proteins that don't have sugars attached to them. As an example, many hormones are peptides with sugars attached to them. Sugars can also be attached to lipids (which are the main component of membranes), such as glycosphingolipids which are also important in immunology and cell signaling. Since the sugars attached to glycoproteins can be very heterogeneous, glycoproteins are harder to isolate and study than proteins without sugars attached to them. People are still working hard to figure out what the sugar attachments to many of these proteins actually do, so it's an exciting area of current research. Wikipedia doesn't have a great entry for them, but you can look up glycoproteins on that site. Also if you're really interested, you can look up an excellent paper by Ajit Varki of UCSD, the reference is: Biological roles of oligosaccharides: all of the theories are correct. Varki A.
