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.
Glycerophospholipids or phosphoglycerides are glycerol-based phospholipids. They are the main component of biological membranes in eukaryotic cells. They are a type of lipid, of which its composition affects membrane structure and properties. [1] Two major classes are known: those for bacteria and eukaryotes and a separate family for archaea. [2]
Glycolipid. Glycolipids are lipids with a carbohydrate attached by a glycosidic (covalent) bond. [1] Their role is to maintain the stability of the cell membrane and to facilitate cellular recognition, which is crucial to the immune response and in the connections that allow cells to connect to one another to form tissues.

Although the functions of plasmalogens have not yet been fully elucidated, it has been demonstrated that they can protect mammalian cells against the damaging effects of reactive oxygen species. [ 1 ] [ 2 ] [ 3 ] In addition, they have been implicated as being signaling molecules and modulators of membrane dynamics.
[2]: 333–4 This is known as the hydrophobic effect. In an aqueous system, the polar heads of lipids align towards the polar, aqueous environment, while the hydrophobic tails minimize their contact with water and tend to cluster together, forming a vesicle ; depending on the concentration of the lipid, this biophysical interaction may result ...
In biological membranes, the phospholipids often occur with other molecules (e.g., proteins, glycolipids, sterols) in a bilayer such as a cell membrane. [7] Lipid bilayers occur when hydrophobic tails line up against one another, forming a membrane of hydrophilic heads on both sides facing the water.
A study confirmed that side effects like pancreatitis and kidney damage are possible while taking GLP-1s like Ozempic. Here's what a doctor wants you to know.
A high concentration of high density lipoproteins-cholesterols (HDL-C) have what is known as a vasoprotective effect on the body, a finding that correlates with an enhanced cardiovascular effect. [9] There is also a correlation between those with diseases such as chronic kidney disease, coronary artery disease, or diabetes mellitus and the ...
