ETHYL OLEATE For Synthesis - Loba Chemie

In vitro studies are generally conducted in animal or human cells or tissues outside of the body. In vitro literally means “in glass”, and refers to procedures carried out on living material or components of living material cultured in petri dishes or in test tubes under defined conditions. These may be contrasted with in vivo studies, or those carried out “in the living animal”. While it is difficult, if not impossible, to project the effects of a chemical on a complex organism when the observations are confined to a single type of cells in a dish, in vitro studies do provide a significant amount of information about intrinsic toxicity as well as cellular and molecular mechanisms of toxicity. In addition, they offer many advantages over in vivo studies in that they are generally less expensive and they may be conducted under more controlled conditions. Furthermore, despite the fact that small numbers of animals are still needed to obtain cells for in vitro cultures, these methods may be considered reduction alternatives (since many fewer animals are used compared to in vivo studies) and refinement alternatives (because they eliminate the need to subject the animals to the adverse toxic consequences imposed by in vivo experiments).

The notice of intent (NOI) is an opportunity for the public to comment on proposed variations to the Significant New Activity (SNAc) Notice issued by the Minister of the Environment to apply the SNAc provisions of the Canadian Environmental Protection Act, 1999 (CEPA) to the substance Clarified oils (petroleum), catalytic cracked, reaction products with cresol and polymethylene polyphenylene isocyanate (Chemical Abstracts Service [CAS] Registry No. 68920-56-9), pursuant to section 85 of CEPA.

In January 2015, a public commitment was made by Environment Canada and Health Canada to review all orders and notices that were adopted between 2001 and 2014 to impose SNAc requirements. The purpose of the review is to ensure that SNAc orders and notices are consistent with current information, policies and approaches. Resulting changes to SNAc orders and notices are expected to provide greater clarity of scope and improved ease of compliance by industry, while protecting Canadians and their environment. This NOI reflects the results of the review of the SNAc Notice on the substance Clarified oils (petroleum), catalytic cracked, reaction products with cresol and polymethylene polyphenylene isocyanate identified by stakeholders as a priority.

As the effects observed are probably the result of the extremely high intake of total dietary fat and fatty acids, these studies were not considered relevant to the safety evaluation of oleic acid at its current level of intake as a flavouring substance.

3. The toxicodynamic phase refers to the interaction of toxicants (molecules, ions, colloids) with specific sites of action on or inside the cells—receptors—ultimately producing a toxic effect.

At this time it is proposed that the notice would require any person (individual or corporation) engaging in a significant new activity in relation to Clarified oils (petroleum), catalytic cracked, reaction products with cresol and polymethylene polyphenylene isocyanate (CAS Registry No. 68920-56-9), to submit a Significant New Activity Notification (SNAN) containing all of the information prescribed in the notice at least 90 days prior to any use of the substance for the significant new activity.

Role of Hydrophobic Interactions.

To track down where exactly the ethyl oleate was synthesized, they coupled oleic acid to a chemical that would produce fluorescence when the oleic acid was combined with ethanol to produce ethyl oleate. Under the microscope, areas that fluoresced showed where ethyl oleate was being made. They found that ethyl oleate was made in the esophagus, honey crop and stomach.

Ethyl palmitate and ethyl oleate are the predominant …

To understand how this chemical is produced in the individual bee and then distributed in the colony, Carlos Castillo and colleagues from Simon Fraser University in British Columbia and the Laboratoire Biologie et protection de L’Abeillie in France looked at several ways to identify the source and synthesis of ethyl oleate. This chemical can be produced by a reaction between oleic acid (a common fatty acid in insects) and ethanol. While you might not think of honeybees as heavy drinkers, it turns out that yeasts in flower nectar ferment the sugars present into ethanol, and so the forager bees have much higher exposure to ethanol than nurse bees.

The authors were also able to identify the genes responsible for the synthesis of ethyl oleate in the honeybee and the resulting enzymes that catalyze the reaction between oleic acid and ethanol. These enzymes are then secreted into the gut fluid, where they produce ethyl oleate, which is then transported to the cuticle.

“Ethyl oleate does not elicit any noticeable behavourial responses in recipient workers,” says , who supervised a recent study on the synthesis of ethyl oleate at Simon Fraser University in British Columbia. “Yet it has a profound physiological effect”.
