These values were significantly lower than those observed in the positive control, thereby showing a protective effect of α-T against the H2O2 toxicity. Overall, the vitamin E α-T isomer protected the immortalized MDPC-23 pulp cells against the toxic effects of H2O2. Thalidomide is racemic — it contains both left and right handed isomers in equal amounts: one enantiomer is effective against morning sickness, and the other is teratogenic. The enantiomers are converted to each other in vivo. That is, if a human is given D-thalidomide or L-thalidomide, both isomers can be In this work, a new kind of N, Cu codoped carbon dots (N/Cu-CDs) was prepared via a facile one-pot hydrothermal method by using citric acid monohydrate, copper acetate monohydrate and diethylenetriamine. The prepared N/Cu-CDs with a high quantum yield (50.1%) showed excitation-independent emission at 460 nm. The structure and fluorescence properties of N/Cu-CDs were characterized by high on the Left we have one way to represent the ethane molecule the only problem with this drawing is it doesn't give us much information about what ethane looks like in three dimensions on the right is another drawing of the ethane molecule but this this drawing gives us more information this is a wedge and dash drawing remember a wedge has a bond coming out at you in space or bond coming out of These values were significantly lower than those observed in the positive control, thereby showing a protective effect of alpha-T against the H2O2 toxicity.

Isomeraser är enzymer som katalyserar \\ n rotation av en isomer till en redoxreaktioner, till exempel katalas: 2 H2O2 -\u003e O2 + 2 H2O 2. Peroxid -> farligt ämne (H2O2) -> toxiskt mot normalfloran, epitelceller.

The (E)- and (Z)-isomers generate the same products in exactly the same amounts. C) Isomers of compounds have a different arrangement of the atoms. Isomer compounds will differ from identical compounds by the arrangement of the atoms. See example below. Both compounds have the same number of atoms, C 5 H 12.
