Ag formation

Other models consider the steps up to and including Ag formation to be rapid in both the forward and reverse directions, thereby setting up an equihbrium condition involving, Ag, and Br, where is a trapped hole and Br is the result of Br neutralization by. In estabUshing... 

Two possible pathways for the biosynthesis of 2-AG have been proposed (1) a phospholipase C (PLC) hydrolysis of membrane phospholipids followed by a second hydrolysis of the resulting 1,2-diacylglycerol by diacylglycerol lipase or (2) a phospholipase Ai (PLA,) activity that generates a lysophospholipid, which in turn is hydrolyzed to 2-AG by lysophospholipase C (Fig. 5) (Piomelli, 1998). Alternative pathways may also exist from either triacylglycerols by a neutral lipase activity or lysophosphatidic acid by a dephosphorylase. The fact that PLC and diacylglycerol lipase inhibitors inhibit 2-AG formation in cortical neurons supports the contention that 2-AG is, at least predominantly, biosynthesized by the PLC pathway (Stella, 1997). However, a mixed pathway may also be plausible. 

The secondary strucmre of DIMS9054 has AG formation value greater than one for DIMS9051 and is represented by a relatively labile hairpin that melts easily when it comes to intermo-lecular interactions between four molecules of DIMS9054 (Figs. 1 and 2) (see Notes 10-12).

Arachidonoyl-bound lysophospholipids such as LPA may contribute to 2-AG formation (Sugiura et al., 2006). LPA can derive either from PLArmediated hydrolysis of PA or by lyso-PLD-mediated hydrolysis oflysophospholipids (Fig. 2). 

Chemical Methods. By far the most celebrated chemical reaction leading to 02( Ag) formation is that of hypohalite with hydrogen peroxide summarized in Eq. (6) [20]. 

Clearly, then, determination of quantum yields for sensitized 02( Ag) formation is crucial for evaluation of the importance of the energy transfer relative to all...
