beta-carbon atom <β-carbon atom>

Beta-Kohlenstoffatom {n} <β-Kohlenstoffatom>biochem.

• It holds the beta-carbon oxygen in place so that it’s in prime position to make the ester linkage.
• The FMN cofactor is first reduced by NADPH, the substrate is then bound, and finally the substrate is reduced by a hydride transfer from NADPH to the substrate’s beta carbon.
• The beta carbon is then deprotonated, creating an alpha-beta unsaturation and pushing a lone pair onto the aldimine nitrogen.
• β-Carbon nitride ("beta"-carbon nitride), β-C3N4, is a superhard material predicted to be harder than diamond.
• Inspection of the alternative phenonium-type species, in which an aryl group has begun to migrate to the beta-carbon, reveals the greater electron delocalization with a substituent para on the migrating aryl group and thus a more stabilized pathway.

• As the alpha carbon is being deprotonated, the pro-R hydrogen of the beta carbon leaves as a hydride to FAD in a concerted step.
• It is believed that one of the graphitic forms of the carbon nitride C3N4 is built up of linked heptazines. Heptazines could be a precursor molecule to the diamond-like beta carbon nitride.
• The HOMO of stabilized enolates has a large coefficient on the central carbon atom while the LUMO of many alpha, beta unsaturated carbonyl compounds has a large coefficient on the beta carbon.
• The structure of beta carbon nitride (β-C3N4) was first proposed by Amy Liu and Marvin Cohen in 1989.
• As it functions in the step immediately preceding the actual beta-oxidation and forms a double bond extending from the beta-carbon (position 2), enoyl-CoA isomerase is involved in both the NADPH-dependent and NADPH-independent pathways of beta-oxidation.

• The beta-carbon is chiral and must have the R-configuration so that the beta-hydroxyl group is oriented towards the Asn-293 residue in helix 6 to form a hydrogen bond essential to binding to the beta-2 receptor.
• They are also a member of the carbon nitride class of materials that include beta carbon nitride (β-C3N4), predicted to be harder than diamond.
• All of these compounds differ from PEP in that the alpha carbon is extended and a ketone is attached to the beta carbon (with the exception of prolintane), among other modifications.
• They feature a phenethylamine core with an alkyl group attached to the alpha carbon, and a ketone group attached to the beta carbon, along with additional substitutions.
• It is also related to methamphetamine, differing by the β-ketone substituent (at the beta carbon) and an ethyl group replacing the methyl group at the carbon alpha to the amine.

• The position of the carbon-carbon double bonds in carboxylic acid chains in fats is designated by Greek letters.
• The α-carbon ("alpha"-carbon) refers to the first carbon atom that attaches to a functional group, such as a carbonyl.
