Glycerophospholipids are derived from glycerol-3-phosphate in a de novo pathway. [3] The term glycerophospholipid signifies any derivative of glycerophosphoric acid that contains at least one O-acyl, or O-alkyl, or O-alk-1'-enyl residue attached to the glycerol moiety. [4] The phosphate group forms an ester linkage to the glycerol.
The binding of agonists such as thrombin, epinephrine, or collagen, to platelet surface receptors can trigger the activation of phospholipase C to catalyze the release of arachidonic acid from two major membrane phospholipids, phosphatidylinositol and phosphatidylcholine.
Examples include phosphatidylinositol (4,5)-bisphosphate (PIP 2), that can be split by the enzyme phospholipase C into inositol triphosphate (IP 3) and diacylglycerol (DAG), which both carry out the functions of the G q type of G protein in response to various stimuli and intervene in various processes from long term depression in neurons [19 ...
Phosphatidylserine (PS) is the major acidic phospholipid class that accounts for 13–15% of the phospholipids in the human cerebral cortex. [7] In the plasma membrane, PS is localized exclusively in the cytoplasmic leaflet where it forms part of protein docking sites necessary for the activation of several key signaling pathways.
Enzyme-linked receptors (or catalytic receptors) are transmembrane receptors that, upon activation by an extracellular ligand, causes enzymatic activity on the intracellular side. [33] Hence a catalytic receptor is an integral membrane protein possessing both enzymatic, catalytic, and receptor functions. [34]
Lecithin (/ ˈ l ɛ s ɪ θ ɪ n / LESS-ith-in; from the Ancient Greek λέκιθος lékithos "yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues which are amphiphilic – they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are ...
The functions of gangliosides as specific determinants suggest its important role in the growth and differentiation of tissues as well as in carcinogenesis. It has been found that tumor formation can induce the synthesis of a new complement of ganglioside, and very low concentrations of a specific ganglioside can induce differentiation of ...
These isomers are common in biology and have many functions, for example taste sensory, regulating phosphate levels, metabolic flux, transcription, mRNA export and translation, insulin signaling, embryonic development and stress response. Cis-inositol is the only isomer not found naturally in nature.
