Cytidine diphosphate glycerol, acid

Glaser and Burger, using membrane preparations of several bacterial species and various nucleotide precursors, prepared in vitro a few kinds of teichoic acids which were identical with samples extracted from the cell walls of the studied strains. The following TA chain precursors were used cytidine diphosphate glycerol (CDP-... 

Figure 21-3 Major pathways of synthesis of fatty acids and glycerolipids in the green plant Arabidopsis. The major site of fatty acid synthesis is chloroplasts. Most is exported to the cytosol as oleic acid (18 1). After conversion to its coenzyme A derivative it is converted to phosphatidic acid (PA), diacylglycerol (DAG), and the phospholipids phosphatidylcholine (PC), phosphatidylinositol (PI), phosphatidylglycerol (PG), and phosphatidylethanolamine (PE). Desaturation also occurs, and some linoleic and linolenic acids are returned to the chloroplasts. See text also. From Sommerville and Browse.106 See also Figs. 21-4 and 21-5. Other abbreviations monogalactosyldiacylglycerol (MGD), digalactosyldiacylglycerol (DGD), sulfolipid (SL), glycerol 3-phosphate (G3P), lysophosphatidic acid (LPA), acyl carrier protein (ACP), cytidine diphosphate-DAG (CDP-DAG).

Complete hydrolysis of phosphatidyl choline yields phosphoric acid, glycerol, saturated and unsaturated fatty acids. Phosphatidyl choline and phosphatidyl ethanolamine are obtained by routes similar to the above (11.102). In eukaryotic cells, various phospholipids are biosynthesised from phosphatidic acid via cytidine diphosphate diacylglycerol (11.103). 

Cytidine diphosphate Ribitol, Glycerol Synthesis of Teichoic acids (see). 

Cytidine phosphates cytidine S -monophosphate (CMP, cytidylic acid, M, 323.2), cytidine 5 -diphos-phate (CDP, M, 403.19) and cytidine 5 -triphosphate (CTP, M, 483.16). For structure, see e. g. Pyrimidine biosynthesis. CTP is a precursor of RNA synthesis, while deoxy-CTP is a precursor of DNA synthesis. CDP may be regarded as the coenzyme of phospholipid biosynthesis (see Membrane lipids) (activated choline is CDP-choline). Glycerol and the sugar alcohol, ribitol, are also activated by bonding to CDP (see Nucleoside diphosphate sugars). Reduction of ribose...
