Why is it better to take a drug as the active enatiomer instead of the racemic mixture?
Enantiomers can have very different effects on the body, which contains many chiral compounds. While one enantiomer may have a healing medicinal effect, the other can be harmful, or at best, ineffective. While it is much more complicated to make a single enantiomer or separate a racemic mixture, taking a single-enantiomer drug often has a much greater effect.

Is Robitussin cough syrup a pure substance or mixture?

What is benzoyl DL-arginine p-nitroaniline hydrochloride?
It is substrate used to measure proteas activity. Trypsin is one of the enzymes it is used for. The compound you mentioned is a racemic mixture and I believe it is only the L form that is an active substrate. Thomas Henriksson, Ph.D.
Is a dispensable tablet mixture of compounds?
Yes, a dispensable tablet is typically a mixture of various compounds, including active pharmaceutical ingredients (APIs) and excipients. The active ingredients provide therapeutic effects, while excipients serve various purposes such as binding, filling, and aiding in the tablet's disintegration and absorption. This combination allows for effective delivery of medication in a convenient form.
Is scope mouthwash a mixture or a compound?
Scope mouthwash is a mixture. It is composed of various ingredients such as water, alcohol, flavoring agents, and active ingredients like menthol or eucalyptol. These components are mixed together to create the final product, which can be separated into its individual parts.
What is difference between a racemic mixture and a meso compound?
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
How is chiral resolution process?
The separation of a racemic mixture into two optically active forms (+ or −) is known as chiral resolution. Since diastereomers have different chemical and physical properties, they can be separated into corresponding enantiomers by chiral resolution. This method is called enantiomeric enrichment, and it is a process of continuously increasing the percentage of enantiomers until the enantiomeric excess finally approaches 100%./BOC Sciences
Does the birth control yaz contain all active pills?
No, Yaz contains a mixture of active and placebo pills.
When is burrowing owls most active?
They are mostly active during the day time, instead of night.
How do you identify isomers?
plane polarised light is being used. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form. A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form. If the solutions are equally concentrated the amount of rotation caused by the two isomers is exactly the same - but in opposite directions. When optically active substances are made in the lab, they often occur as a 50/50 mixture of the two enantiomers. This is known as a racemic mixture or racemate. It has no effect on plane polarised light.
Is bleach a mixture or a pure substance?
This depends on the type of bleach; many are mixtures.
When should active voice be used instead of passive voice?
Active voice should be used instead of passive voice when the focus is on the subject performing the action, rather than the action being done to the subject.
Is expectorant a suitable cough mixture for mild cough?
Yes, especially those with guaifenesin as the active ingredient.
What is chiral purity?
Chiral purity refers to the degree of enantiomeric excess in a sample of a chiral compound, which measures the ratio of one enantiomer to the other. A sample with high chiral purity contains mostly one enantiomer and little to no contamination from the other enantiomer or a racemic mixture. Chiral purity is important in fields like pharmaceuticals where the specific enantiomer of a compound can have different biological effects.
When do you use broken instead of broke?
I broke my leg. (active voice) My leg is broken. (passive voice) Active voice vs. Passive voice.
How long do mice hibernate?
They do not hibernate.
What does 10 to 1 dilution mean?
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
