*  DD  ORGANIC COMPOUNDS (Class 532, Subclass 1) {1}
1  DF  .~ Fatty compounds having an acid moiety which contains the carbonyl of a carboxylic acid, salt, ester, or amide group bonded directly to one end of an acyclic chain of at least seven (7) uninterrupted carbons, wherein any additional carbonyl in the acid moiety is (1) part of an aldehyde or ketone group, (2) bonded directly to a noncarbon atom which is between the additional carbonyl and the chain, or (3) attached indirectly to the chain via ionic bonding {23}
223.~.~ Acyclic carbon-to-carbon unsaturation in the acid moiety {1}
224  DF  .~.~.~> Plural carbon-to-carbon unsaturation in the acid moiety (e.g., polyunsaturated fatty acids, etc.)

DEFINITION

Classification: 554/223

(under subclass 1) Compounds wherein the acid moiety contains an acyclic ethylenic double bond or an acetylenic triple bond.

(1) Note. Products referred to as being unsaturated with no specificity regarding the degree of unsaturation are included in this subclass, as well as "named" products commonly known to possess unsaturation. Also included herein are products which consist of mixtures of saturated and unsaturated fatty acids and/or esters, unless a constituent of the mixture is provided for in a higher subclass, or a claim is directed to a specific constituent provided for elsewhere.
