Functional acylglycerides
View Patent ↗The present invention relates to the field of human and animal nutrition, and in particular to certain novel compositions of conjugated linoleic acids (CLA). In particular, the present invention relates certain isomers of conjugated linoleic acids at either the SN1 and SN3 or SN2 positions of the acylglyceride molecule and another fatty acyl residue at the other of the SN1 and SN3 or SN2 positions of the acylglyceride molecule. These novel acylglyceride compositions containing conjugated linoleic acyl residues, medium chain fatty acyl residues, long chain fatty acyl residues, and ω3, ω6, and ω9 fatty acyl residues are efficacious as pharmaceutical compositions, animal feed additives, and human dietary supplements.
1. An acylglyceride having the following structure:
wherein R1 and R3 are acyl residues selected from the group consisting of 10,12; 9,11; 8,10; and 11,13 octadecadienoate and R2 is selected from the group consisting of medium chain fatty acyl residues.
2. The acylglyceride of claim 1 , wherein said medium chain fatty acyl residue is selected from the group consisting of acyl residues of the following acids: decanoic acid, undecanoic acid, 10-undecanoic acid, lauric acid, cis-5-dodecanoic acid tridecanoic acid, myristic acid, and myristoleic acid.
3. A powder comprising at least one type of acylglyceride as set forth in claim 1 .
4. An oil comprising at least one type of acylglyceride as set forth in claim 1 .
5. The oil of claim 4 , wherein said oil further comprises an antioxidant.
6. A food composition comprising at least one type of acylglyceride as set forth in claim 1 .
7. The food composition of claim 6 , wherein said food composition is a functional food, nutritional supplement food, infant food, pregnancy food, or elderly food.
8. A pharmaceutical composition comprising at least one type of glyceride as set forth in claim 1 .
9. A nutritional or pharmaceutical composition comprising at least one type of acylglyceride as set forth in claim 1 and a carrier suitable for oral, intraintestinal, or parenteral administration.
