Photo, thermal and chemical degradation of riboflavin
Beilstein Journal of Organic Chemistry, 2014 Riboflavin (RF), also known as vitamin B2, belongs to the class of water-soluble vitamins and is widely present in a variety of food products. It is sensitive to light and high temperature, and therefore, needs a consideration of these factors for its ...

Microbial degradation of nicotine-N'-oxide. I. Degradation products. [PDF]
Agricultural and Biological Chemistry, 1978 Bacteria degrading nicotine-N′-oxide were isolated from tobacco leaves and soil of tobacco field. The bacterial metabolites from nicotine-N′-oxide were identified to be N′- methylmyosirune and 4′-keto-4′-(3-pyridyl)butylic acid, and four unidentified compounds were present.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Solid phase microextraction (SPME) as an effective means to isolate degradation products in polymers [PDF]
, 1997 A new sample preparation technique, solid phase microextraction (SPME), was compared with direct headspace-GC-MS with respect to the type and amount of identified compounds. Three types of LDPE films containing photosensitising additives according to the

CATALYTIC DEGRADATION OF POLYMERS .3. DEGRADATION OF POLYSTYRENE [PDF]
, 1990 Silica, alumina, silica-aluminas and zeolites were screened as catalysts for polystyrene degradation in the range 200-550°C. More than 80% of the products in the distillate from the catalytic reactions at T≥350°C comprised eleven main compounds, in ...

Ascorbate degradation: pathways, products, and possibilities
Journal of Experimental BotanyAbstract A role for l-ascorbate as the precursor of several plant compounds adds to its already broad metabolic utility. There are many examples of plant species in which oxalate and l-threonate are formed from l-ascorbate breakdown, and a number of roles have been proposed for this: structural, physiological, and biochemical.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Phosphoinositides and inositol phosphates as molecular glues
FEBS Letters, EarlyView.Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.
