They serve as the most basic building blocks to proteins?

They are comprised of proteins?

They fight diseases in an immune response?

Who really knows?

The -R group that is attached to the alpha carbon?

How each amino acid bonds to another amino acid when forming a protein?

It's Pka value?

The alpha carbon is where the amino acid connects to other amino acids in order to form polymers (Proteins)?

The alpha carbon is a chiral carbon (with the exception of leucine) that attaches to the -R group?

The alpha carbon is a chiral carbon that attaches to the -R group, the amino group, a hydrogen and a carboxylic acid?

Chirality means that a molecule can rotate polarized light and has optical activity because it is attached to four different functional groups. It also refers to its symmetry on a chiral carbon and that if a 3D version is reflected in a mirror, its image in non superimposable.

Chirality means that the chiral carbon is the most important carbon in reactiveness for the molecule and that its mirror image is superimposable.

Chirality means that a molecule only has one alpha carbon.

The horizontal lines represent constituent bonds that are coming out of the plane of the page towards the viewer. The vertical lines represent bonds between carbon atoms that are going into the plane of the page away from the viewer. The "L" and "D" stand for levorotatory (Left) and dextrorotatory (Right).

The "L" means levorotary and stands for left. Molecules that are of the L designation means that they will rotate a beam of polarized light to the left if projected into solution of L molecules. The "R" designation means dextrorotary and stand for right. Molecules that are of the R designation will turn a beam of polarized light to the right if projected into a solution of R molecules. The L and D designation is significant in protein synthesis because the body only uses "L" AA's.

A structural isomer is the least similar of all isomerism. They only share the same molecular formula and therefor have the same molecular weight of other structural isomers. Aside from that, there spatial arrangement and connectivity are completely different from molecule to molecule.

A structural isomer is the most similar of all isomerism. They share the same molecular formula and therefor have the same molecular weight of other structural isomers. This means they also have similar chemical properties that will be common in how they react with other molecules.

A structural isomer is the written representation of a molecule in line form.

A structural isomer is the least similar of all isomerism. They share the same molecular formula and therefor have the same molecular weight of other structural isomers. This means that they have the same physical properties such as boiling point and melting point.

Same molecular formula, same molecular weight, different structure?

Different molecular formula, same molecular weight, same structure?

Same molecular formula, same molecular weight, same structure?

Same molecular formula, different molecular weight, same structure?

Stereoisomers are isomeric molecules that have the same molecular formula and sequence of bonded atoms (constitution), that also have the same three-dimensional orientations of their atoms in space.

Two molecules are described as stereoisomers of each other if they are made of the same atoms, connected in the same sequence, but the atoms are positioned differently in space. The difference between two stereoisomers can only be seen when the three dimensional arrangement of the molecules is considered.
