Is fat the sixth taste primary? Evidence and implications [PDF]

open access: yes, 2015
Explores our tongue\u27s ability to detect fat as a distinct taste similar to our ability to sense sweet, sour, bitter, acid and savory. Abstract Taste is the chemical sense responsible for the detection of non-volatile chemicals in potential foods. For

Biocatalytic Route to Chiral Precursors of β-Substituted-γ-Amino Acids [PDF]

open access: yes, 2011
In this work, we utilized commercial lipases (from Thermomyces lanuginosa, Rhizopus delemar, and Mucor miehei) as biocatalysts for the efficient synthesis of precursors of β-substituted-γ-amino acids.

Effect of Additional Amino Group to Improve the Performance of Immobilized Lipase From Aspergillus niger by Adsorption-Crosslinking Method

open access: yesFrontiers in Energy Research, 2021
Adsorption-crosslinking is one of the immobilization methods to improve the reusability of lipase. It requires amino groups to reduce cross-link immobilization risk so that lipase–support interaction increases and the immobilization is attainable.

Body mass index and hepatic lipase gene (LIPC) polymorphism jointly influence postheparin plasma hepatic lipase activity

open access: yesJournal of Lipid Research, 1998
The -514 polymorphism in the hepatic lipase gene (LIPC) is associated with decreased hepatic lipase activity. In the present study, the interaction between body mass index (BMI), the -514 polymorphism, and hepatic lipase activity was examined in 118 ...

Protective effects of urocortin 2 against caerulein-induced acute pancreatitis. [PDF]

open access: yes, 2019
Because little is known about the role of corticotropin-releasing factor (CRF) agonists in regulating responses in pancreatitis, we evaluated the effects of urocortin 2 (UCN2) and stressin1 in caerulein-induced acute pancreatitis (AP) model in rats. Male

Lipase activity in the human aorta

open access: yesJournal of Lipid Research, 1970
The hydrolysis of triglycerides by grossly normal male human aortas has been studied in vitro. The tissue contains an acid lipase (pH optimum, 5.4) and an alkaline lipase (pH optimum, 8.8). Both lipases catalyze the hydrolysis of saturated triglycerides;
