It formed whenever a carbon atom is bonded to four different groups.

• pI

• Chirality

• Zwitterion

• Amphoteric

It is the only amino acid with no asymmetric carbon because it has two hydrogens attached to alpha carbon.

• Tyrosine

• Alanine

• Glycine

• Phenylalanine

The pH at which the amino acid exists in its zwitterionic form is called:

• isolectric point

• electric pH

• isotonic pH

• isoelectric pH

It is used to visualize the spots of different amino acids.

• Ninhydrin Solution

• Butanol- Acetic Acid Solution

• Starch-Saliva Mixture

• Fehlings Solution
