What is the role of a LED in a circuit?

In electronics, an LED circuit or an LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must supply enough current to illuminate the…

What is the difference between HD and 4k?

The difference between Ultra HD and 4K. From a technical point of view, “Ultra High Definition” is actually a derivative of the 4K digital cinema standard. However, while your local…

What is a chiral resolution?

Chiral resolution in stereochemistry is a process for separating racemic compounds into their enantiomers. It is an important tool in the production of optically active drugs. Other terms with the…

How does a chiral column work?

Chromatographic column chromatography is a variant of column chromatography in which the stationary phase contains a single enantiomer of a chiral compound rather than an achiral. … As with all…

How do you separate two enantiomers?

The separation of a raceme in its components, pure enantiomers, is called chiral resolution. There are various methods, including crystallization, chromatography and the use of enzymes. To effectively differentiate both…

Are D and L glucose Epimers?

It is said that two carbohydrates are enantiomers if they are mirror images that are unmatched by one another. One example of the enantiomer is the D and L isomers…

What is a diastereomer?

Diastereomers (sometimes called diastereoisomers) are a type of stereoisomer. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations on one or more (but not all) of…

What is a chiral and achiral?

In chemistry, chirality usually refers to molecules. Two mirror images of a chiral molecule are called enantiomers or optical isomers. Enantiomers pairs are often called “right”, “left handed” or if…

What does Achiral mean?

A molecule is achiral if it is superimposable to its mirror image. Most achiral molecules have a symmetry plane or a symmetry center. Achiral molecules containing a stereocentre are called…

What is an example of an enantiomer?

Just as our hands are mirror images of each other, molecules can also have mirror images that can not be superimposed on them. These molecules are called enantiomers. An example…

What is an isomer example?

In structural isomers, sometimes referred to as constitutional isomers, atoms and functional groups are joined in different ways. Structural isomers have different IUPAC names and may or may not belong…
