Blood types are an example of how glycolipids on cell membranes mediate cell interactions with the surrounding environment. The four main human blood types (A, B, AB, O) are determined by the oligosaccharide attached to a specific glycolipid on the surface of red blood cells, which acts as an antigen. The unmodified antigen, called the H ...
A blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins , carbohydrates , glycoproteins , or glycolipids , depending on the blood group system.
Globoside 4 (Gb4) has been known as the receptor for parvovirus B19, due to observations that B19V binds to the thin-layered chromatogram of the structure.However, the binding on its surface does not match well with the virus, which raised debates on whether or not GB4 is the cause for productive infection.

CD1a, CD1b, and CD1c subtypes present lipid antigens to T cells, while CD1d cells present lipids, glycolipids, and lipoproteins to Natural killer T cells. CD1 a through c cell subtypes initiate T helper type 1 and type 2 responses, and they facilitate sulfatide loading onto the surface of the cells. [ 3 ]
The heads of glycolipids (glyco- stands for sugar) contain a sphingosine with one or several sugar units attached to it. The hydrophobic chains belong either to: two fatty acids (FA) – in the case of the phosphoglycerides, or; one FA and the hydrocarbon tail of sphingosine – in the case of sphingomyelin and the glycolipids.
Some studies link GLP-1 drugs for diabetes with neuroprotective benefits but others say that some of these drugs may increase depression risk, a new review concludes.
Because protein is the foundation of our cells, it plays an important role in every bodily function, including supporting muscle health and healthy immune function., While we focused on protein ...
The glycocalyx (pl.: glycocalyces or glycocalyxes), also known as the pericellular matrix and cell coat, is a layer of glycoproteins and glycolipids which surround the cell membranes of bacteria, epithelial cells, and other cells. [1] Animal epithelial cells have a fuzz-like coating on the external surface of their plasma membranes.
