Synthesis of structured triacylglycerols containing medium-chain and long-chain fatty acids by interesterification with a stereoespecific lipase from Mucor miehei.

The scientific rationale and clinical application of short-chain fatty acids and medium-chain triacylglycerols.

Cette revue discute les bases scientifiques et les applications cliniques des lipides a chaine courte (LCC) et des triacylglycerols chaine moyenne (TCM). Les LCC sont produits dans le cdlon des mammifitres B la suite de la fermentation microbienne des fibres, de l’amidon non digCrC, et des protCines de l’alimentation. Leur concentration dans les segments diffkrents du cdlon est affectCe par l’a...

Synthesis of structured triacylglycerols enriched in n-3 fatty acids by immobilized microbial lipase

The search for new biocatalysts has aroused great interest due to the variety of micro-organisms and their role as enzyme producers. Native lipases from Aspergillus niger and Rhizopus javanicus were used to enrich the n-3 long-chain polyunsaturated fatty acids content in the triacylglycerols of soybean oil by acidolysis with free fatty acids from sardine oil in solvent-free media. For the immob...

Inhibition of Thermophilic Anaerobic Digestion of Waste Food by Long Chain Fatty Acids and Propionate

Enzymatic preparation of structured oils containing short-chain fatty acids.

Structured oils prepared by enzymatic transacylation with triacylglycerols (TAGs) and various fatty acids (FAs) were characterized. Transacylation with trilaurin and saturated FAs (C4:0-C16:0) was performed using Lipozyme RM-IM under standard reaction conditions. The structured oils thus produced had transacylation ratios of 25-37%, as medium-chain FAs > long-chain FAs > short-chain FAs. This r...

Synthesis of long-chain polyunsaturated fatty acids in preterm newborns fed formula with long-chain polyunsaturated fatty acids.

BACKGROUND Docosahexaenoic acid (DHA) and arachidonic acid (AA) are long-chain polyunsaturated fatty acids (LCPs) that play pivotal roles in growth and neurodevelopment. OBJECTIVE We aimed to quantify the synthesis of LCPs in preterm infants fed infant formula containing LCPs. DESIGN Twenty-two preterm infants were randomly assigned to either the no-LCP group (fed formula without LCPs; n = ...
