Abstract

2-Hydroxy-3-aminopropionic acid derivatives of the general formula I ##STR1## where X is hydrogen, an alkali metal or ammonium which may be substituted by C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -hydroxyalkyl, and Y.sup.1 and Y.sup.2 have the following meanings: PA0 A) .omega.-substituted alkyl of the general formula EQU --(CH.sub.2).sub.m --R.sup.1 PA0 where R.sup.1 is hydrogen, hydroxyl or --COOX, --NH--CH(COOX)--CH.sub.2 --COOX or --NY.sup.1 Y.sup.2 and m is from 1 to 20, although m is not 1 when Y.sup.1 and Y.sup.2 are identical and R.sup.1 is --COOX, PA0 B) a polyether group of the general formula EQU --(CH.sub.2 CH.sub.2 O).sub.m --R.sup.2 PA0 where R.sup.2 is hydrogen or C.sub.1 -C.sub.4 -alkyl, PA0 C) a .beta.-hydroxyl-substituted group of the general formula ##STR2## where R.sup.3 is --COOX, --CH.sub.2 OH or --CH.sub.2 --NY.sup.1 Y.sup.2 and n is from 1 to 5, PA0 D) an .alpha.-carboxyl-substituted group of the general formula ##STR3## where R.sup.4 is hydrogen, methyl or hydroxymethyl and R.sup.5 is hydroxymethyl or --CH(OH)--COOX or --(CH.sub.2).sub.p --COOX, where p is 1 or 2, PA0 E) pyranosyl or furanosyl of the general formula ##STR4## where q is 3 or 2, or F) a po…
