This method requires the knowledge of molar ratios of the components of the solution at which each HA appears in the solution. It is shown that in an HF-Me2CO solution the main part of the molecules is involved in the HA composition starting from the HF content similar to 0.25 molar ...
dracunculus and the essential oils and extracts derived from this species as safe for use [307]. However, there have also been reports of the potential toxicity of the main components of the essential oil of A. dracunculus—estragole and methyl eugenol [54]. In animal studies, these ...
The power of mouse genetics has been fundamental to further dissecting the role of Wnt signaling components during ISC homeostasis. For instance, Ras-like proto-oncogenes A and B (RalA and RalB), two GTPases involved in Wnt signalosome endocytic activation, were recently shown to be required f...
Identification of small molecules is a critical task in various areas of life science. Recent advances in mass spectrometry have enabled the collection of tandem mass spectra of small molecules from hundreds of thousands of environments. To identify which molecules are present in a sample, one can ...
Boundary structures are formed by organic components of the Murchison carbonaceous chondrite The first cellular systems to appear on the Earth were presumably assembled from three molecular species: information-storing molecules capable of replicat... Deamer,W David - 《Nature》 被引量: 338发表: 1985...
Multiple-stimulus-responsive supramolecular gels of two components and dual chiroptical switches. The studies of CD spectra suggested that the supramolecular chirality induced by self-assembled chiral gelator molecules in gels could be tuned by the ... W Miao,L Qin,D Yang,... - 《Chemistry》 被...
waxy cornstarch with casein were prepared and characterised. They were prepared from casein in defatted milk and corn and waxy corn starches phosphated to degree of substitution values (DS) of 0.0637 and 0.0968, respectively. The components were blended in starch to casein ratios of 2:1, 1:1...
Testing a variety of amphiphilic molecules, measurements yielded values of zero, plus or minus one elementary net charge within a margin of error. The experimental set-up described here can be used for lateral separation, enrichment and isoelectric focusing of membrane components. 展开 ...
Long chain dibasic acids (LCDAs) are components of biodegradable aliphatic polyester plastics, which are synthesized from alkane petrochemicals. Numerous enzymes and organisms have been identified that convert aliphatic polyesters into LCDAs and diols. However, it is challenging to convert LCDAs back ...
(FWHM), and, finally, a fast truncation. The SLM was specifically used for spectral phase modulation of spectral components between 815 and 816 nm. In addition, wavelengths longer than ~816 nm were blocked by a razor blade, situated directly in front of the SLM. This was necessary due...
