42 results about "Beta oxidation" patented technology

In biochemistry and metabolism, beta-oxidation is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH₂, which are co-enzymes used in the electron transport chain. It is named as such because the beta carbon of the fatty acid undergoes oxidation to a carbonyl group. Beta-oxidation is primarily facilitated by the mitochondrial trifunctional protein, an enzyme complex associated with the inner mitochondrial membrane, although very long chain fatty acids are oxidized in peroxisomes.

Method for activating the lipid catabolic metabolism in enteric epithelium and improving the lipid metabolism in enteric epithelium

Disclosed are a method for activating lipid metabolism in the small intestine epithelium and also a method for promoting accumulation of fatty acids into the small intestine epithelium, each of which features administering an effective amount of a diacylglycerol. Also disclosed are methods for improving various symptoms in diabetes, which have ingesting a diacylglycerol. Ingestion of the diacylglycerol leads to accumulation of the fatty acids in the small intestine. The fatty acids so accumulated promote induction of beta-oxidation, thereby not only activating lipid catabolism but also making it difficult to allow lipids to accumulate as triacylglycerols. This series of actions eventually results in development of lowering action for blood remnant-like lipoprotein level and also lowering action for blood leptin level, and hence, lipid metabolism is improved. Further, energy consumption is enhanced by promoting the induction of beta-oxidation and activating lipid catabolism.

Also, such AEC decreases de novo synthesis and increases disposal of triglycerides (TG) in humans via PPAR activation and SREBP deactivation. Such drop in TG by AEC reverses maladies of insulin resistance (IR) and metabolic syndrome (MS), prediabetes, diabetes and diabetes-related cardiovascular diseases (CVD).

Natamycin fermentation technology based on addition of exogenous saturated fatty acid

The invention discloses a natamycin fermentation technology based on addition of exogenous saturated fatty acid. By adding a slow-release precursor source, namely the saturated fatty acid, which has no toxic or side effects on cells, when beta-oxidation utilization is conducted in the cells, the exogenous saturated fatty acid generates a large quantity of acetyl CoA precursors and NADH, thus supply of natamycin macrolide precursors and ATP is guaranteed, and product synthesis is promoted. Since the saturated fatty acid is in a solid state under normal temperature and is not dissolved in water,the concentration of the saturated fatty acid cannot influence cell growth and metabolism in a fermentation liquor, and therefore, in the technology, rigid control over the concentration of the saturated fatty acid is not needed. By means of the technology, the biosynthesis level of the natamycin can be effectively improved, the detection and material supply operation load of precisely regulatingthe precursor concentration in the fermentation liquor is greatly lowered, and the technology has important application value in the industry.

Application of P110 alpha in preparation of reagent for regulating and controlling animal energy metabolism

The invention belongs to the technical field of biology, and particularly relates to application of P110 alpha in preparation of a reagent for regulating and controlling animal energy metabolism. The research finds that the weight of a P110 alpha CKO mouse is reduced. The mouse P110 alpha gene is massively knocked out in the liver and is mainly knocked out in liver sinus endothelial cells (LSECs), and meanwhile, CNP is prompted to be massively expressed in the liver and is mainly expressed in the LSECs. The up-regulation of FGF21 in LSECs of the P110 alpha CKO mouse causes the increase of the FGF21 protein expression of the liver and the FGF21 level of serum, which is possibly caused by the weakening of the synthesis of the liver and white fat (WAT), the enhancement of fatty acid-beta oxidation, the increase of the energy consumption of the body and the weight loss.
