Diagram of mediator with cyclin-dependent kinase module. Mediator is a multiprotein complex that functions as a transcriptional coactivator in all eukaryotes.It was discovered in 1990 in the lab of Roger D. Kornberg, recipient of the 2006 Nobel Prize in Chemistry.
Ekplexite is a unique sulfide-hydroxide niobium-rich mineral with the formula (Nb,Mo)S 2 •(Mg 1−x Al x)(OH) 2+x. [5] [3] It is unique because niobium is usually found in oxide or, eventually, silicate minerals.
The ground state is a triplet radical with two unpaired electrons (X̃ 3 B 1), [10] and the first excited state is a singlet non-radical (ã 1 A 1). With the singlet non-radical only 38 kJ above the ground state, [ 10 ] a sample of methylene exists as a mixture of electronic states even at room temperature, giving rise to complex reactions.
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
The following outline is provided as an overview of and topical guide to organic chemistry: Organic chemistry is the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives.
In supramolecular chemistry, [1] host–guest chemistry describes complexes that are composed of two or more molecules or ions that are held together in unique structural relationships by forces other than those of full covalent bonds. Host–guest chemistry encompasses the idea of molecular recognition and interactions through non-covalent ...
This is a list of important publications in chemistry, organized by field. [1] [2] [3] [4]Some factors that correlate with publication notability include: Topic creator – A publication that created a new topic.
The science of molecules is called molecular chemistry or molecular physics, depending on whether the focus is on chemistry or physics. Molecular chemistry deals with the laws governing the interaction between molecules that results in the formation and breakage of chemical bonds, while molecular physics deals with the laws governing their ...
