Homework Help: organic

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: http://users.ox.ac.uk/~mwalter/web_06/Resources/biosynthesis/amino_acids/amino_acids_roughguide.shtml

Thank you for clarifying! Obviously this is NOT my area of expertise! Try the following, please:

1. (Wikipedia): http://en.wikipedia.org/wiki/Amino_acid

2. (part II of #1); http://en.wikipedia.org/wiki/Alpha-amino-acid_esterase

3. http://medical-dictionary.thefreedictionary.com/alpha-amino+acid
