Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]
arXiv, 1999 Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.

The Plant Journal, 2001 Phospholipid metabolism is involved in plant responses to drought and salinity stress. To investigate the role of phospholipase D (PLD) and its product phosphatidic acid (PtdOH) in stress signalling, we isolated a novel PLD cDNA, designated AtPLDdelta ...

Extraction Methods and an Investigation of Drosophila Lipids [PDF]
, 1959 In earlier work (8) we extracted lipids from dried, macerated Drosophila melanogaster with ether, but later, working with larger quantities of undried flies, we found that most of the phospholipids were autolyzed.

Role of phosphatidic acid in plant galactolipid synthesis [PDF]
Biochimie, 2012 Phosphatidic acid (PA) is a precursor metabolite for phosphoglycerolipids and also for galactoglycerolipids, which are essential lipids for formation of plant membranes. PA has in addition a main regulatory role in a number of developmental processes notably in the response of the plant to environmental stresses.

Acceptors of fatty acid for glyceride synthesis in guinea pig mammary gland
Journal of Lipid Research, 1964 Glycerides are shown to be synthesized by two pathways in mammary tissue of lactating guinea pigs. One pathway involves the direct acylation of monoglycerides.

Biotechnology for Biofuels, 2018 Background Triacylglycerols (TAGs) rich in medium-chain fatty acids (MCFAs, C10–14 fatty acids) are valuable feedstocks for biofuels and chemicals. Natural sources of TAGs rich in MCFAs are restricted to a limited number of plant species, which are ...

Are Strong Bronsted Acids Necessarily Strong Lewis Acids? [PDF]
arXiv, 2006 The Broensted and Lowry acid base theory is based on the capacity of proton donation or acceptance (in the presence or absence of a solvent) whereas the Lewis acid base theory is based on the propensity of electron pair acceptance or donation. We explore through DFT calculation the obvious question whether these two theories are in conformity with each

Human Type 2 Phosphatidic Acid Phosphohydrolases
Journal of Biological Chemistry, 1998 Phosphatidic acid (PA), lysophosphatidic acid, ceramide 1-phosphate (C1P), and sphingosine 1-phosphate (S1P) are lipid mediators generated by phospholipases, sphingomyelinases, and lipid kinases.
