Alpha Carbon

Some articles on alpha carbon, alpha, carbon, alpha carbons:

Keto-enol Tautomerism - Mechanism
... by a two step mechanism in an aqueous acidic solution.For this it is necessary that the alpha carbon(carbon closest to functional group) contains at least one hydrogen atom known as alpha hydrogen.This atom is ... The existence of hydrogen atom at alpha carbon is necessary but not sufficient condition for enolization to occur ... In order to be acidic, the alpha hydrogen should be positioned such that may line up parallel with antibonding pi-orbital of the carbonyl group ...
Idh1 - Catalytic Mechanism - Steps
... The products of the reaction are alpha-ketoglutarate, carbon dioxide, and NADH + H+/NADPH + H+ ... The second box is Step 1, which is the oxidation of the alpha-C (C#2) ... In this process, the alcohol group off the alpha-carbon (C#2) is deprotonated and the electrons flow to the alpha-C forming a ketone group and removing a hydride off C#2 using NAD+/NADP+ as an ...
HNCOCA Experiment
... acid residue is transferred to the amide nitrogen, and then to the alpha carbon of the previous residue in the protein's amino acid sequence ... complementary HNCA experiment transfers magnetization to the alpha carbons of both the starting residue and the previous residue in the sequence ... HNCOCA experiment is used, often in tandem with HNCA, to assign alpha carbon resonance signals to specific residues in the protein ...
Idh1 - Catalytic Mechanism - Detailed Mechanism
... (w6 and w8) in the Mn2+ isocitrate porcine IDH complex to deprotonate the alcohol off the alpha-carbon atom ... The oxidation of the alpha-C also takes place in this picture where NAD+ accepts a hydride resulting in oxalosuccinate ... Along with the sp3 to sp2 stereochemical change around the alpha-C, there is a ketone group that is formed form the alcohol group ...

Famous quotes containing the word alpha:

    Imagination is a valuable asset in business and she has a sister, Understanding, who also serves. Together they make a splendid team and business problems dissolve and the impossible is accomplished by their ministrations.... Imagination concerning the world’s wants and the individual’s needs should be the Alpha and Omega of self-education.
    Alice Foote MacDougall (1867–1945)
