Abstract The objective of this study was to characterize the chemical composition in extracts atemoya (var. Thompson) seed oil by spectrometric methods. following extraction methods were performed: using hexane, mechanical a press, and partitioned extraction. each analysed gas chromatography-mass spectrometry (GC-MS), more than 100 compounds identified. major constituents hexane (Z)-hexadec-9-e...
A two-parameter equation to reproduce the droplet size distribution (DSD) of emulsions has been developed. The equation has been applied atisfactorily to oil-in-water (O/W) emulsions with triolein and tributyrin as oil phase and gum arabic, an alkylpolyglucoside and a fatty ethoxilated lcohol as emulsifier agents. Emulsions with aging effect also have been studied. The equation reproduces satis...
Conclusive evidence has been obtained for the presence of both hepatic and extrahepatic triglyceride lipase activities (TGLA) in rat postheparin plasma, and an assay has been devised for their selective measurement. Heparin-released TGLA in plasma from the intact rat, like TGLA in postheparin hepatic perfusate, was relatively resistant to inactivation by salt and protamine. Postheparin TGLA obt...
Radiolabeled cholesteryl oleate, when incorporated into phospholipid vesicles, was hydrolyzed at acid pH by an enzyme present in rabbit aortic homogenates. In contrast, cholesteryl oleate presented as an acetone dispersion was not effectively hydrolyzed at acid pH under identical conditions. Using the vesicle preparation as substrate, a sensitive assay system for the acid hydrolase was develope...
The ability of water-insoluble molecules such as triacylglycerols to partition from oil phases into phospholipid interfaces may be crucial to their hydrolysis by lipases in the aqueous environment of plasma and cells. This study uses high resolution and magic angle spinning 13C NMR spectros-copy to measure the solubility of the 8-carbon medium chain triacylglycerol, trioctanoin, in the lamellar...
BACKGROUND AND AIMS Peripancreatic fat necrosis occurs frequently in necrotising pancreatitis. Distinguishing markers from mediators of severe acute pancreatitis (SAP) is important since targeting mediators may improve outcomes. We evaluated potential agents in human pancreatic necrotic collections (NCs), pseudocysts (PCs) and pancreatic cystic neoplasms and used pancreatic acini, peripheral bl...
Human hepatic lipase (hHL) mainly exists cell surface bound, whereas mouse HL (mHL) circulates in the blood stream. Studies have suggested that the carboxyl terminus of HL mediates cell surface binding. We prepared recombinant hHL, mHL, and chimeric proteins (hHLmt and mHLht) in which the carboxyl terminal 70 amino acids of hHL were exchanged with the corresponding sequence from mHL. The hHL, m...
Malnutrition resulting from chronic congestive heart failure (cardiac cachexia, CC) is not uncommon and contributes to mortality and morbidity especially of elderly people. The aetiology of cardiac cachexia is probably multifactorial. We have assessed whether malabsorption of fat is associated with CC and if so whether it is due to small-bowel bacterial overgrowth. Three groups of subjects were...
Obesity is associated with cognitive impairments. Long-term mechanisms for this association include consequences of hyperglycemia, dyslipidemia, or other factors comprising metabolic syndrome X. We found that hypertriglyceridemia, the main dyslipidemia of metabolic syndrome X, is in part responsible for the leptin resistance seen in obesity. Here we determined whether triglycerides have an imme...
