Glycoprotein - Wikipedia
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 …
Glycoprotein Definition and Function - ThoughtCo
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.
Glycoprotein – Definition, Structure, Functions, Examples
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...
An Introduction to Glycoproteins | The Scientist Magazine®
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.
16.6: Glycoproteins - Biology LibreTexts
A cell membrane and its glycocalyx are illustrated below. Oligosaccharides begin their synthesis in the rough endoplasmic reticulum (RER), with the creation of a core glycoside. Partial glycans are enzymatically linked to compatible amino acids of a membrane protein.
16.8: Glycoproteins and Human Health - Biology LibreTexts
We’ll close this chapter with a few examples of glycoproteins that play crucial roles in human physiology. Let’s look first at the major human blood groups. The major A, B, AB, O and Rh blood groups result from the presence or absence of glycoprotein antigens embedded in red blood cell membranes and the presence or absence in the blood, of ...
Glycoproteins: Synthesis and Clinical Consequences
2024年10月21日 · Introduction to Glycoproteins. Membrane associated carbohydrate is exclusively in the form of oligosaccharides covalently attached to proteins forming glycoproteins, and to a lesser extent covalently attached to lipid forming the glycolipids.
