Amino Acids Flashcards
what do amino acids contain?
have both amine and carboxylic acid functional group
what do amino acids make?
peptides which form proteins
what is the general formula of amino acids?
RCHNH2CO2H
what is the simplest amino acid?
glycine (however not optically active)
R=H
what is an amino acid with R=CH3 known as?
alanine
what happens during reaction of alanine and glycine?
addition elimination reaction
alanine loses OH and glycine loses one H from other group to join the compounds together
what is a dipeptide?
a compound made from two constituent amino acids
what is the peptide linkage
during the reaction of alanine and glycine where both compounds come together.
c double bond to O and N H bond
what is a compound that isnt an amino acid but has a peptide linkage called?
an amide
in dipeptides where is the free amino group always on?
the left
in dipeptides where is the free carboxylic acid group always on?
the right
