If you’re not familiar with some of the terms used in this discussion – some key ones are described here for your reference:Bio-inorganic chemistry – the study of the role of metals in biological processes. This includes naturally occurring molecules and artificially introduced proteins.Metal center (active site) – the active metal in a larger molecule that reacts in (or catalyzes) a reactionCatalysis – increasing the rate of a reaction by introducing a substance to the reaction know as a catalyst. Catalysts are not consumed in the reaction.Functionalization of Carbon-Hydrogen bonds – converting a (Carbon-Hydrogen) C-H bond to a C-R bond. R represents a functional group that enables the final molecule to perform a specific reaction.Activation of Carbon-Hydrogen bonds – Reading (or breaking) the C-H bond so that the desired functional group can replace the Hydrogen.Enzyme – An organic catalyst, often found in nature and active in living cells. Enzymes are typically protein molecules.Organic molecule/organic substrate – A compound containing Carbon.Hydrogen bonding – An electrostatic force of interaction between a Hydrogen atom and another electronegative atom. The most common Hydrogen bonds occur between Hydrogen and either Nitrogen, Oxygen, or Fluorine.Reoxidize (oxidize) – during a reaction, a catalyst may accept electrons from the primary reactants or otherwise become reduced. Removing those electrons, or otherwise oxidizing the catalyst enables it to once more catalyze the reaction.Stoichiometric amount – Calculating the number of molecules (usually in moles) required for a given reaction.Photochemistry – Chemical reactions which are influenced by the presence or absence of light, often at specific wavelengths. Photochemistry is used to closely control reactions – i.e. the reaction will not take place if the correct light isn’t present.Motif – A specific part of a molecule – often found in a number of molecules. Prof Maiti is contactable on social media, and you can find him on LinkedIn at https://www.linkedin.com/in/debabrata-maiti-54ab622a/ Our theme music is "Wholesome" by Kevin MacLeod (https://incompetech.com)Music from https://filmmusic.ioLicense: CC BY (http://creativecommons.org/licenses/by/4.0/) Connect with me (Paul) at https://www.linkedin.com/in/paulorange/H.E.L. group can be found at www.helgroup.com online,on LinkedIn at https://www.linkedin.com/company/hel-group/ on Twitter, we're @hel_group, https://twitter.com/hel_groupor search for us on Facebook
