摘要:
Disclosed herein are polar lipid mixtures, comprising glycerophospholipids such as phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS) and phosphatidylinositol (PI), and sphingolipids such as sphyngomyelin (SM). Most importantly, the ratio of phospholipids in said mixture is comparable to that of HMF, and is represented by SM>PC>PE>PS>PI or SM=PC>PE>PS>PI. Processes for the preparation of said mixtures and uses thereof are also described herein.
摘要:
The subject invention thus provides a composition comprising at least one triglyceride, at least one phospholipid and at least one poly-unsaturated fatty acids (LC-PUFA); wherein at least about 1% of the LC-PUFA in the composition is conjugated to said at least one phospholipid and uses thereof.
摘要:
The present invention provides a new enzymatic process for preparing 1,2-diacylated phospholipids comprising the use of an enzyme preparation possessing phospholipase activity towards acylation at the sn-1 and sn-2 sites in a microaqueous reaction system. More particularly, the 1,2-diacyl-phospholipids produced according to the esterification/transesterification process of the present invention are obtainable in high yield and purity and carry identical desired carboxylic acid, preferably fatty acid, acyl groups at the sn-1 and sn-2 positions. The process involves esterification/transesterification (acylation) of a glycerophospholipid, preferably glycerophosphoryl choline (GPC) with a desired carboxylic acid, preferably fatty acid, or their derivatives in the presence of the above mentioned appropriate enzyme preparation. The process of the invention further relates to a process for the production of 1-acyl-2-lyso-glycerophospholipid, preferably 2-lyso-PC by reacting glycerophospholipid, preferably glycerophosphoryl choline (GPC) with a desired carboxylic acid, preferably fatty acid, or their derivatives in the presence of a sn-1 specific phospholipase (PLA1 or PLA1,2) and a solvent, in a microaqueous medium.
摘要:
The present invention refers to a method for ore or both of improving sleep in a subject and treating at least one sleep problem in a subject. The method comprises administering to the subject an edible lipid composition which comprises a vegetable-derived fat source, wherein the fat source is a triglyceride fat source comprising triglycerides with 15-55% palmitic acid moieties out of the total fatty acids, and wherein the level of palmitic acid moieties at the sn-2 position of the glycerol backbone is at least 30% of total palmitic acid.
摘要:
A preparation for treatment and/or prevention of seizures comprising a non-mammalian derived mixture of serine glycerophospholipids (PS) conjugates, wherein the mixture comprises (a) Eicosapentaenoic acid (EPA) conjugated to PS and (b) Docosahexaenoic acid (DHA) conjugated to PS, and methods of treatment of seizures with same.
摘要:
Disclosed is the use of a lipid composition in the preparation of a formulation for reducing the frequency and duration of crying periods in an infant, the lipid composition comprising a vegetable-derived fat source, wherein the fat source is a triglyceride fat source comprising triglycerides with 15-55% palmitic acid moieties out of the total fatty acids, and wherein the level of palmitic acid moieties at the sn-2 position of the glycerol backbone is at least 30% of total palmitic acid.
摘要:
The invention relates to a process for the selective alcoholysis of a free sterol, by contacting said free sterol with a fat-based product, optionally with the addition of carboxylic fatty acid(s) and/or ester derivative(s) thereof that are not derived from said fat-based product, in the presence of an immobilized lipase complex which may optionally be surfactant-coated, which complex possesses a high level of sterol-specific alcoholytic and/or esterfication activity and minimal acidolytic and transesterification activities. The fat-based product is a nutritional product or food, particularly butterfat, or a cosmetic or cosmetic or cosmetic-related product. The process may be used for preparing substantially cholesterol-free fat-based products, particularly products containing butterfat, by selectively esterfying any free cholesterol contained therein by the immobilized, preferably surfactant coated lipase. The invention also relates to a process for the in situ enrichment of a fat-based product with esterified phytosterol ester(s). In this process, the esterification of the phytosterol is simultaneously accompanied by esterification of any free cholesterol present in said fat-based product.
