The enzyme aminocyclopropane-1-carboxylic acid synthase (ACC synthase, ACS) (EC 4.4.1.14) catalyzes the synthesis of 1-Aminocyclopropane-1-carboxylic acid (ACC), a precursor for ethylene, from S-Adenosyl methionine (AdoMet, SAM), an intermediate in the Yang cycle and activated methyl cycle and a useful molecule for methyl transfer:
[1] [2] Some of the commonly used grades of purity include: ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses.
Anglo-Chinese School (Independent) (ACS(I)) is an independent Methodist secondary school in Dover, Singapore.Founded in 1886 by Reverend William Fitzjames Oldham, it was recognised as an International Baccalaureate World School in 2005, and has since consistently ranked among the top three schools worldwide that offer the IB Diploma Programme.
ACS Sustainable Chemistry & Engineering is a weekly peer-reviewed scientific journal published by the American Chemical Society. [1] [2] It covers research in green chemistry, green engineering, biomass, alternative energy, and life cycle assessment. [3] According to Journal Citation Reports, the journal has an impact factor of 7.1 in 2023. [4]
However, changes made in the CET test content, format, and scoring systems are evidence of the endeavors to bring about positive washback of the test on English teaching and learning in China. It is the expectation of the CET committee that the test can reflect and catch up with the needs of rapid economic reform and the new open-door policy.
In 1874, a group of American chemists gathered at the Joseph Priestley House to mark the 100th anniversary of Priestley's discovery of oxygen.Although there was an American scientific society at that time (the American Association for the Advancement of Science, founded in 1848), the growth of chemistry in the U.S. prompted those assembled to consider founding a new society that would focus ...
In task 1, test-takers answer opinion questions on familiar topics. They are evaluated on their ability to speak spontaneously and convey their ideas clearly and coherently. In tasks 2 and 4, test-takers read a short passage, listen to an academic course lecture or a conversation about campus life, and answer a question by combining appropriate ...
Cellulose is a polymer composed of β-1,4-linked glucosyl residues. β-glucosidases, cellulases (endoglucanases), cellobiosidases (exoglucanases) are required by a number of organisms to consume it. These enzymes are powerful tools for degradation of plant cell walls by pathogens and other organisms consuming plant biomass. β‑glucosidases ...
