“…The latter can react with the hydroxyl group of either Ser or Tyr to yield a thiohemiacetal. Under continuous UV exposure, the C–S bond of the thiohemiacetal is expected to cleave, either homolytically or heterolytically [92,93,94], and the vinyl ether is generated via subsequent oxidation and deprotonation, respectively [95]. An important difference between the results of both growth hormones is the formation of an ether cross-link in mGH vs. a vinylether cross-link in hGH.…”

“…Hence, compound 27 was suggested to be methylthiomethyl dithioformate. Methylthiomethyl dithioformate has been identified as a primary photoproduct of 254 nm irradiation of an MeCN solution of 1,3,5-trithiane . However, the mass spectrum of methylthiomethyl dithioformate was not reported.…”

“…Chemicals and solvents used in the experiments were dimethyl sulfide, pent-1-en-3-one, 1-hexanethiol, ( Z )-hex-3-enal, 2,4-dithiapentane, oct-1-en-3-one, dimethyl trisulfide, ( Z )-hex-3-enol, 2-isopropyl-3-methoxypyrazine, methional, ( Z )-dec-4-enal, (2 E ,6 Z )-nona-2,6-dienal, tris­(methylthio)­methane, 3-phenylpropionaldehyde, β-ionone, 1 M lithium triethylborohydride in THF (Sigma-Aldrich Japan, Tokyo, Japan), carbon disulfide, THF (Junsei Chemical Co., Ltd., Tokyo, Japan), and methyl iodide (Tokyo Chemical Industry Co., Ltd., Tokyo, Japan). The following compounds were synthesized by using reported methods: hydrogen sulfide and methanethiol, hept-1-en-3-one, methylthiomethanethiol, 2,3,5-trithiahexane, methylthiomethyl dithioformate, 2,4,5,7-tetrathiaoctane, and 1,2,4,6-tetrathiepane . Methyl dithioformate was synthesized as described below.…”

“…The shape of such curve depends on numerous factors, such as: the structure of the absorbing molecules, solvent type, solution pH, measurement conditions, and the presence of impurities. The type of instrument used to take measurements also plays an important role [16,17]. Absorption spectra for brown coal solutions were recorded with the use of the Ultra-3660 UV-ViS double-beam spectrophotometer for measuring the transmission and absorbance of solid, liquid, and gaseous bodies with a high-quality diffraction grating ensuring high measurement accuracy and stability.…”

“…The course of the absorption spectrum curves obtained corresponds to a monotonically decreasing line. The decreasing nature of humic acid spectra in the UV-ViS range is related to their structure (the occurrence of aromatic rings and groups of quinone and semiquinone nature in their structure) [17,18,19].…”
