6.2.2 - Amino acids, Amides and Chirality Flashcards
What is the general formula for amino acids ?
RCH(NH₂)COOH
What amino acid wouldn’t have a chiral carbon
Glycine where the R group is a Hydrogen. Therefore it will not be optically active.
What happens when an amino acid reacts with an alkali.
Use glycine as an examplen
It will react with the carboxylic group on the amino acid to form a conjugate base
What happens when an amino acid reacts with a strong acid.
Use 2-aminopropanoic acid as an example
A H+ ion from the acid will react with the amine group on the amino acid. To form a conjugated acid
Amino acid reaction with alcohols
See 6.1.3
How would a primary amide look like
How would a secondary amide look like
How would a tertiary amide look like
What are optical isomers
Are non-superimposable mirror images (know as enantiomers) of each and have a chiral carbon atom.
What makes a carbon a chiral centre ?
Has four different groups attached to it.
What will optical actively compounds do ?
Reflect plane polarised light.
