Homocysteine Disulphides and Vascular Disease
The total plasma concentration of homocysteine is a marker of this amino acid's atherogenic potential. However, the homocysteine pool exists almost entirely as oxidized homocysteine equivalents (OHcyE), composed of homocystine and cysteine-homocysteine disulphides (20-30%), and protein-bound disulphide (70-80%). We have noticed that the total concentration of OHcyE in injured coronary artery ti...
متن کاملOrganic photolysis reactions in tropospheric aerosols: effect on secondary organic aerosol formation and lifetime
This study presents the first modeling estimates of the potential effect of gasand particle-phase organic photolysis reactions on the formation and lifetime of secondary organic aerosols (SOAs). Typically only photolysis of smaller organic molecules (e.g., formaldehyde) for which explicit data exist is included in chemistry–climate models. Here, we specifically examine the photolysis of larger ...

متن کاملUV Photolysis and Creation of Complex Organic Molecules in the Solar Nebula
Two proposed possibilities for the complex organics are that they are a) formed by Streck synthesis in ancient sub-surface aquifers on asteroid parent bodies [2], or b) by accretion of material created in the ISM [3,4]. Measured D/H ratios of the meteoritic amino acid samples imply a low-temperature origin, challenging model a). And dense molecular clouds are nearly opaque to UV penetration, ch...
