Hormonal (endocrine) system

The endocrine glands produce chemicals called hormones and pass them directly into the bloodstream. Hormones can be thought of as chemical messages. From the bloodstream, hormones communicate with the body by targeting their target cell to cause a particular change or effect in that cell. The hormone can also create changes in the cells of …

Glycolysis

What is glycolysis? Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates. Glycolysis is an ancient metabolic pathway, meaning it evolved a long time ago and is found in the vast majority of living organisms today. In organisms that perform cellular respiration, glycolysis is …

Feedback Products

How do you get product feedback? If you wish to receive feedback, you must request it. You may receive unsolicited emails from customers with various comments (usually bug reports), but if your customers don’t know you’re looking for their opinion, they’re unlikely to go out of their way to let you know what they think. …

Gas chromatography techniques to evaluate the hydrogen permeation characteristics in rubber: ethylene propylene diene monomer

Gas chromatography techniques to evaluate the hydrogen permeation characteristics in rubber: ethylene propylene diene monomer

We established an ex-situ approach for evaluating hydrogen gasoline permeability by thermal desorption evaluation (TDA) gasoline chromatography (GC) and by self-developed diffusion evaluation software program. Absorbed hydrogen mass in rubber, associated to the GC-peak space, is recorded as a operate of elapsed time after decompressing the hydrogen below high-pressure. From the charging quantity (CH0) and …

Method development in interaction polymer chromatography

Method development in interaction polymer chromatography

Interaction polymer chromatography (IPC) is an umbrella time period overlaying a big number of primarily enthalpically-dominated macromolecular separation strategies. These embody temperature-gradient interaction chromatography, interactive gradient polymer elution chromatography (GPEC), barrier strategies, and so forth. Also included are strategies reminiscent of liquid chromatography on the vital circumstances and GPEC in conventional precipitation-redissolution mode. IPC methods …

Gas chromatography-mass spectrometry based metabolomic approach to investigate the changes in goat milk yoghurt during storage

Gas chromatography-mass spectrometry based metabolomic approach to investigate the changes in goat milk yoghurt during storage

The general objective was to make the most of a fuel chromatography spectrometry based metabolomics approach to investigate the metabolite changes in goat milk yoghurt during storage. A complete of 129 metabolites have been recognized in goat milk yoghurt during 28 days refrigerated storage. Among 129, 39 metabolites have been differentially regulated (p < 0.05) …

Quantification of ustalic acid, a chemotaxonomic marker, in Tricholoma ustale using liquid chromatography-mass spectrometry

Quantification of ustalic acid, a chemotaxonomic marker, in Tricholoma ustale using liquid chromatography-mass spectrometry

The improvement of strategies for the detection and qualification of poisonous substances in mushrooms is a quickly rising analysis space in forensic toxicology. This examine aimed to find out liquid chromatographic and mass spectrometric circumstances relevant to the evaluation of ustalic acid (UA) in Tricholoma ustale. We used HPLC coupled with single quadrupole mass spectrometry …

Triazine-based covalent porous organic polymer for the online in-tube solid-phase microextraction of polycyclic aromatic hydrocarbons prior to high-performance liquid chromatography-diode array detection

Triazine-based covalent porous organic polymer for the online in-tube solid-phase microextraction of polycyclic aromatic hydrocarbons prior to high-performance liquid chromatography-diode array detection

A triazine-based covalent organic porous polymer (COP) was synthesized from the monomers 1,3,5-triphenylbenzene and tricyanogen chloride through the Friedel-Crafts response and characterised intimately utilizing Brunauer-Emmett-Teller evaluation, X-ray photoelectron spectroscopy, elemental evaluation, and scanning electron microscopy, which confirmed that the COP had a tough floor and appropriate extraction web site. It was then employed in in-tube …
