A molecule, such as H20, is the smallest unit of a compound that maintains the characteristics of that compound. A compound often looks and behaves differently from its constituent elements. Consider a water (H2O)molecule, which is made up of two hydrogen atoms and one oxygen atom. Both hydr...
Stoichiometry refers to the calculations made to find amount of reactants and products in a chemical reaction. Stoichiometry is based on the law of conservation of mass, where the total mass of reactants will have to produce an equal amount of products, supposing the reaction has a 100% rea...

Significance was assessed with a Student's t-test t-test (ns: not significant). 3.4. CPT1A-specific inhibitor Etomoxir can reduce BoHV-1 virus replication Etomoxir (ETO) is a chemical inhibitor of FAO that has irreversible effects on inhibiting CPT1A activity (Xu et al., 2003). To ...
In addition to examining the kinetics of the h20S proteasome activity in the presence or absence of Aβ peptides, we use gel electrophoresis, LC-MS, and TOF-MS/MS analyses to examine the degradation of Aβ(1−42) by the h20S proteasome. The observed peptide fragments resulting from ...
A chemical element is a common name given to all atoms which have the same number of protons in their nucleus. Examples of elements are chlorine, zinc, and hydrogen. A chemical compound is formed when two or more chemical elements come together and bond electronically (either by electron-...
ChemFormula is a Python class for working with chemical formulas. It allows parsing chemical formulas, calculating formula weights for stoichiometric calculations, and generating formatted output strings (e.g. HTML). - molshape/ChemFormula
