Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
56 words
An alkyl ester of a phospholipid acid of the formula ##STR8## wherein R 1 and R 2 are the same or different and each stands for a substituted or unsubstituted alkyl of 5 to 25 carbon atoms or haloalkyl of 6 to 25 carbon atoms and R 3 is alkyl of 6 to 18 carbon atoms.
Claim 2
Dependent Claim
56 words
An alkyl ester of a phospholipid acid of the formula ##STR8## wherein R 1 and R 2 are the same or different and each stands for a substituted or unsubstituted alkyl of 5 to 25 carbon atoms or haloalkyl of 6 to 25 carbon atoms and R 3 is alkyl of 6 to 18 carbon atoms.
Claim 3
Dependent Claim
65 words
An alkyl ester of a phospholipid acid of the formula ##STR9## wherein R 1 and R 2 are selected from substituted and unsubstituted linear and branched alkyl of 5 to 25 carbon atoms and R 3 is selected from saturated and unsaturated, straight chain and branched alkyl of 6 to 18 carbon atoms which may be substituted by halogen, and the physiologically acceptable salts thereof.
Claim 4
Dependent Claim
65 words
An alkyl ester of a phospholipid acid of the formula ##STR9## wherein R 1 and R 2 are selected from substituted and unsubstituted linear and branched alkyl of 5 to 25 carbon atoms and R 3 is selected from saturated and unsaturated, straight chain and branched alkyl of 6 to 18 carbon atoms which may be substituted by halogen, and the physiologically acceptable salts thereof.
