A glycoprotein is a compound containing carbohydrate (or glycan) covalently linked to protein. The carbohydrate may be in the form of a monosaccharide, disaccharide(s), oligosaccharide(s), polysaccharide(s), or their derivatives (e.g. sulfo- or phospho-substituted).

2021年1月22日 · A glycoprotein is part of an extremely diverse group of linked amino acid and carbohydrate chains. Glycoproteins are found throughout nature and have a similarly diverse range of functions. They are one of two glycoconjugates – the …

2019年12月8日 · A glycoprotein is a type of protein molecule that has had a carbohydrate attached to it. The process either occurs during protein translation or as a posttranslational modification in a process called glycosylation.

2024年4月1日 · Glycoproteins are intricate macromolecules characterized by the covalent linkage of amino acid and carbohydrate chains. These entities are ubiquitously present in nature and exhibit a vast array of functions. They belong to the category of glycoconjugates, which also encompasses glycolipids.

2021年2月24日 · Glycoproteins are molecules that comprise protein and carbohydrate chains that are involved in many physiological functions including immunity. Many viruses have glycoproteins that...

2023年7月18日 · Glycoproteins are a large and diverse group of proteins to which one or more sugar molecules, known as oligosaccharides, have been attached through covalent bonding. These diverse proteins have a wide range of functions, including roles in immune response activation, cell signaling, and disease processes.

Any protein molecule with a carbohydrate attached is known as a glycoprotein. The protein’s polypeptide side chains are covalently joined to the carbohydrate, an oligosaccharide chain (glycan). Either the process takes place during protein translation, or it occurs post-translationally via glycosylation.

2022年5月14日 · Most of the proteins exposed to the watery surroundings at the surface of cells are glycoproteins. This image shows the primary structure of glycophorin A, a glycoprotein that spans the plasma membrane ("Lipid bilayer") of human red blood cells. Each RBC has some 500,000 copies of the molecule embedded in its plasma membrane.

Glycoproteins are complexes which are made up of molecules that are either oligosaccharide-peptide or oligosaccharide-protein, in which the protein/peptide chain is covalently bonded with an oligosaccharide chain [1–3].

2024年5月21日 · What Is a Glycoprotein? A glycoprotein is a molecule that contains both a protein portion and at least one carbohydrate portion. Glycoproteins are common in biology and perform a range of functions. Some examples of their individual functions are as structural cell components, enzymes, or hormones.
