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 word "triacylglycerol" is sometimes used synonymously with "triglyceride". In these compounds, the three hydroxyl groups of glycerol are each esterified, typically by different fatty acids. Because they function as an energy store, these lipids comprise the bulk of storage fat in animal tissues.
Niger seed oil is obtained from the edible seeds of the Niger plant, which belongs to the genus Guizotia of the family Asteraceae. The botanical name of the plant is Guizotia abyssinica. Cultivation for the plant originated in the Ethiopian highlands, and has since spread from Malawi to India. [102] Poppy seeds, used to make poppyseed oil
Triglycerides are formed from the esterification of 3 molecules of fatty acids with one molecule of trihydric alcohol, glycerol (glycerine or trihydroxy propane). In the process, 3 molecules of water are eliminated. The word "triglyceride" refers to the number of fatty acids esterified to one molecule of glycerol.
Glycerophospholipids have three components: fatty acid lipid groups (orange), glycerol backbone (white), and 3-phosphate ester (green) Glycerol 3-phosphate is a starting material for de novo synthesis of glycerolipids .
Based on whether the sn-1 lipid is unsaturated next to the ether linkage, they can be further divided into alkenyl-acylphospholipids ("plasmenylphospholipid", 1-0-alk-1’-enyl-2-acyl-sn-glycerol) and alkyl-acylphospholipids ("plasmanylphospholipid"). This class of lipids have important roles in human cell signaling and structure.
Diacylglycerol is a precursor to triacylglycerol (triglyceride), which is formed in the addition of a third fatty acid to the diacylglycerol under the catalysis of diglyceride acyltransferase. Since diacylglycerol is synthesized via phosphatidic acid, it will usually contain a saturated fatty acid at the C-1 position on the glycerol moiety and ...
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 ...
