Example of six stable isotopocules of ethanol (i.e. with stable isotopes) out of the total number of 288 stable isotopocules. Isotopocules are isotopically substituted molecules, which differ only in their isotopic composition or their isotopes' intramolecular position. [1] "
Depending on the formula and the symmetry of the structure, there might be several isotopomers of one isotopologue. For example, ethanol has the molecular formula C 2 H 6 O. Mono-deuterated ethanol, C 2 H 5 DO or C 2 H 5 2 HO, is an isotopologue of it. The structural formulas CH 3 −CH 2 −O−D and CH 2 D−CH 2 −O−H are two isotopomers ...
Modern simultaneous CHNS combustion analyzer. Elemental analysis is a process where a sample of some material (e.g., soil, waste or drinking water, bodily fluids, minerals, chemical compounds) is analyzed for its elemental and sometimes isotopic composition.
Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
Advanced Placement (AP) examinations are exams offered in United States by the College Board and are taken each May by students. The tests are the culmination of year-long Advanced Placement (AP) courses, which are typically offered at the high school level. AP exams (with few exceptions [1]) have a multiple-choice section and a free-response ...
To graduate from high school, a student only needed to pass a sixth grade level test. [1] As a result, 24-25% of new college freshmen needed remedial help. This level of literacy was unacceptable for the demands of the 21st century. The SOL set the bar higher for test-oriented education and performance-driven results.
In molecular biology and pharmacology, a small molecule or micromolecule is a low molecular weight (≤ 1000 daltons [1]) organic compound that may regulate a biological process, with a size on the order of 1 nm [citation needed]. Many drugs are small molecules; the terms are equivalent in the literature.
Astral microtubules are a subpopulation of microtubules, which only exist during and immediately before mitosis.They are defined as any microtubule originating from the centrosome which does not connect to a kinetochore. [3]
