which is false about naturally occurring a-amino acids?
they belong to the D family of chiral compounds related to D-glyceraldehyde
all are chiral except for glycine
each has a characteristic isoelectric point the ph at which there is no net migration of the amino acid toward either electrode in an electrophoresis experiment
they form salts with both strong acids and strong bases
Is it a-amino acids or amino acids? Try this site on amino acids: (Broken Link Removed)
Thank you for clarifying! Obviously this is NOT my area of expertise! Try the following, please:
