-are mirror images of one another.

Thalidomide and l-dopa, shown below, are examples of pharmaceutical drugs that occur as enantiomers, or molecules that are mirror images of one another

Explanation;

-Enantiomers are chiral molecules that are mirror images of one another. Furthermore, the molecules are non-superimposable on one another. This means that the molecules cannot be placed on top of one another and give the same molecule. Chiral molecules with one or more stereocenters can be enantiomers.

Enantiomers have identical chemical and physical properties in an achiral environment. They rotate the direction of plane polarized light to equal, but opposite angles and interact with other chiral molecules differently.

Which of the following statements about a typical plasma membrane is correct?a. Phospholipids are the primary component that det
nordsb [41]

Answer:

B

Explanation:

The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.

What is smaller then an atom?
Alexxx [7]

Answer:

In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.
