Definitions

• This invention relates to triglyceride preparations for enteral or parentral administration to prevent catabolism and to increase protein synthesis in subjects undergoing severe metabolic stress.
• This invention provides medium chain and long chain fatty acids chemically synthesized into structured triglycerides (lipids) for enteral or parentral administration as the lipid calorie source, in subjects undergoing severe metabolic stress.
• lipids structured triglycerides
• the structural lipids of this invention are randomly rearranged mixtures of medium chain triglycerides (MCT) and long chain triglycerides (LCT). They may be represented by the following formula,
• R 1 and R 2 may be independently a C 6 to C 12 acid, or a C 12 to C 18 ' acid, and R 3 may be a C 18 " or C 18 " acid.
• R 1 may be a C 6 to C 12 acid
• R 2 a C 12 to C 18 acid.
• C 18 ', C 18 " and C 18 " represent the number of double bonds in the fatty acid moiety being one, two and three double bonds respectively.
• the medium chain triglycerides may be lauric oils such as, balassee oil, coconut oil, cohune oil, palm kernel oil, tucum oil and fractions thereof.
• the preferred medium chain triglyceride oil is coconut oil.
• the long chain triglycerides may be polyunsaturated vegetable oils such as, corn oil, peanut oil, safflower oil, soybean oil, sunflower seed oil, and fish oils.
• the preferred long chain triglyceride oils are safflower oil, soybean oil, and sunflower seed oil.
• the percent composition of mixtures of medium chain triglycerides to long chain triglycerides of this invention may be 70 to 30%, 80 to 20%, 85 to 15%, or 90 to 10%. The 80 to 20% and the 85 to 15% mixtures are most preferred.
• the structured lipids of this invention may be mixtures of coconut oil and soybean oil, which lipids may have the following fatty acid carbon chain length (CCL) composition.
• CCL fatty acid carbon chain length
• the present invention provides enteral and parenteral preparations for use in stressed patients to prevent catabolism and to increase protein synthesis.
• the preparations provide from about 15 to 85% of the fat calories required in the stressed patient.
• compositions of this invention provide in a 70 Kg man, from about 0.7 gms of fat/Kg of body weight day to about 4.0 gms of fat/Kg of body weight/day.
• the lipid compositions are preferably administered with additional amino acids, vitamins and minerals as required. Modified amino acid formulas specifically designed for stressed subjects are preferred.
• the amino acids, vitamins and minerals can be administered in the same solution as the structured lipids or separately. It is preferred that the component groups be separately packaged to facilitate tailoring the diet to the patients specific needs.
• formulations may include preservatives or stablizers, as required.
• a structural lipid preparation of this invention is compared with a medium chain lipid, and a long chain lipid for the oxidation of lipids in traumatized animals.
• Group I a 20% medium chain lipid emulsion composed of 72.5% capric acid (C 8:0) and 27.5% coprylic acid (C 10:0) (obtained from Travenol Laboratories, Inc; Deerfield/ Illinois).
• Group II a 20% long chain triglyceride emulsion (20% Travamulsion®, Travenol Laboratories)
• Group III a 20% lipid emulsion composed of structured triglycerides chemically synthesized from 80% coconut oil and 20% soybean oil.
• Captex 710A Lot No. KH4022A Capital City Products Co., Columbus, Ohio
• the rats were placed in metabolic chambers that permitted the collection and analysis of their expired breath. At 15 minute intervals for twelve hours, the specific activity of expired carbon dioxide was determined. At the end of the study, the animals were sacrificed
• Such structured lipids should be preferable and suitable for both enteral and parenteral nutrition.
