... During chlorophyll degradation, large amounts of the isoprenoid alcohol phytol are released. The pathway of phytol catabolism has been studied in humans, because chlorophyll is part of the human diet, but little is known for plants. In humans, phytanoyl‐CoA derived from phytol is degraded via α‐oxidation by phytanoyl‐CoA hydroxylase (PAHX) and 2‐hydroxy‐phytanoyl‐CoA lyase (HPCL). Arabidopsis cont ...
... Propargylic alcohols and amines are versatile building blocks in organic synthesis. We demonstrate a straightforward enzymatic cascade to synthesize enantiomerically pure propargylic alcohols and amines from readily available racemic starting materials. In the first step, the peroxygenase from Agrocybe aegerita converted the racemic propargylic alcohols into the corresponding ketones, which then w ...

Abstract:
... A popular approach to mathematical modeling of the combined effect of temperature, pH, water activity, oxygen tension, and the concentration of salts, sugars, alcohol, and/or antimicrobials on microbial growth rate is known as the gamma hypothesis. It is based on the notion that the growth rate, however defined, can be expressed as a multiplication product of algebraic terms each constructed from ...
... Soil particle density is commonly determined using the pycnometer and the volumetric flask methods. These methods could be improved or even replaced to simplify the routine analysis, reduce analysis time and generation of residues, and minimize the maintenance costs of sophisticated equipment. We aimed to develop a practical methodology to determine particle density using only a precision scale, s ...

Abstract:
... The rising world population and its corresponding energy demands pose a considerable burden on natural energy sources. The exploitation of fossil fuels at such an alarming rate blurs the goals of sustainable development and controlling global warming as pledged during the Paris Agreement. Due to the detrimental effects of exhausts from conventional diesel fuel on the environment, biodiesel has ear ...
... Driven by the demand for various cationic biopolymers in recent years, the quaternization of cellulose nanofibers was carefully investigated to have tight control over their final characteristics. The addition of sodium hydroxide (NaOH) to the reaction mixture is crucial as it catalyzes the conversion of alcohol groups of cellulose into more reactive alcoholate groups. On the other hand, excessive ...

... Since low serum l-arginine (Arg) and high asymmetric dimethylarginine (ADMA) can predict microvascular complications in type 2 diabetes mellitus (T2DM), we tested whether Arg and ADMA are affected by diet and physical activity in overweight/obese and T2DM subjects. We tested the effects on serum Arg and ADMA of single loads of dextrose, protein, fat, or alcohol (∼300 calories each); one episode of ...
... Surfactants are known to enhance the foliar uptake of agrochemicals by plasticizing the transport-limiting barrier of plant cuticles. The effects of two different polydisperse alcohol ethoxylates with a low degree [mean ethoxylation of 5 ethylene oxide units (EOs)] and a high degree (mean ethoxylation of 10 EOs) of ethoxylation on cuticular barrier properties were investigated. The diffusion of th ...
