Isozymes (and allozymes) are variants of the same enzyme. Unless they are identical in their biochemical properties, for example their substrates and enzyme kinetics, they may be distinguished by a biochemical assay. However, such differences are usually subtle, particularly between allozymes which are often neutral variants.
Alloenzymes (or also called allozymes) are variant forms of an enzyme which differ structurally but not functionally from other allozymes coded for by different alleles at the same locus. These are opposed to isozymes , which are enzymes that perform the same function, but which are coded by genes located at different loci.
In chemistry, azide (/ ˈ eɪ z aɪ d /, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure − N=N + =N −.It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1]
Amino acid replacement is a change from one amino acid to a different amino acid in a protein due to point mutation in the corresponding DNA sequence. It is caused by nonsynonymous missense mutation which changes the codon sequence to code other amino acid instead of the original.
The C-N distance in isocyanides is 115.8 pm in methyl isocyanide.The C-N-C angles are near 180°. [3]Akin to carbon monoxide, isocyanides are described by two resonance structures, one with a triple bond between the nitrogen and the carbon and one with a double bond between.
The depth of analysis depends on the field of study or the chemical and physical properties of interest. The English word "isomer" ( / ˈ aɪ s əm ər / ) is a back-formation from "isomeric", [ 2 ] which was borrowed through German isomerisch [ 3 ] from Swedish isomerisk ; which in turn was coined from Greek ἰσόμερoς isómeros , with ...
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Aerobic organisms use atmospheric dioxygen as the terminal oxidant in cellular respiration in order to obtain chemical energy. The ground state of dioxygen is known as triplet oxygen, 3 [O 2], because it has two unpaired electrons. The first excited state, singlet oxygen, 1 [O 2], has no unpaired electrons and is metastable.
