[11] The cofactor 3,5-dihydro-5-methyldiene-4H-imidazol-4-one (MIO) is involved in the reaction and sits atop the positive pole of three polar helices in the active site, which helps to increase its electrophilicity. [12] MIO is attacked by the aromatic ring of L-phe, which activates the C-H bond on the β carbon for deprotonation by a basic ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)
Catch bonds were first proposed in 1988 in the Proceedings of the Royal Society by M. Dembo et al. while at Los Alamos National Laboratory.While developing molecular model to study the critical tension required to detach a membrane bound to a surface through adhesion molecules, it was found that it is theoretically possible for bond dissociation to be increased by force, decreased by force ...
In organic chemistry, enols are a type of functional group or intermediate in organic chemistry containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a portmanteau deriving from "-ene"/"alkene" and the "-ol". Many kinds of enols are known. [1]
The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction. The type of addition that occurs depends on multiple different factors of a reaction, and is defined by the final orientation of the substituents on the parent molecule .
The anion [Ce(NO 3) 6] 2− has T h (idealized O h) molecular symmetry.The CeO 12 core defines an icosahedron. [4]Ce 4+ is a strong one-electron oxidizing agent.In terms of its redox potential (E° ≈ 1.61 V vs. N.H.E.) it is an even stronger oxidizing agent than Cl 2 (E° ≈ 1.36 V).
AMP can be produced from ADP by the myokinase (adenylate kinase) reaction when the ATP reservoir in the cell is low: [5] [6] 2 ADP → ATP + AMP. Or AMP may be produced by the hydrolysis of one high energy phosphate bond of ADP: ADP + H 2 O → AMP + P i. AMP can also be formed by hydrolysis of ATP into AMP and pyrophosphate: ATP + H 2 O → ...
