Gluconeogenesis from storage wax in the cotyledons of jojoba seedlings.
The cotyledons of jojoba (Simmondsia chinensis) seeds contained 50 to 60% of their weight as intracellular wax esters. During germination there was a gradual decrease in the wax content with a concomitant rise in soluble carbohydrates, suggesting that the wax played the role of a food reserve. Thin layer chromatography revealed that both the fatty alcohol and fatty acid were metabolized. The di...
متن کاملDevelopment and properties of a wax ester hydrolase in the cotyledons of jojoba seedlings.
The activity of a wax ester hydrolase in the cotyledons of jojoba (Simmondsia chinensis) seedlings increased drastically during germination, parallel to the development of the gluconeogenic process. The enzyme at its peak of development was obtained in association with the wax body membrane, and its properties were studied. It had an optimal activity at alkaline pH (8.5-9). The apparent K(m) va...
متن کاملNeutral lipid biosynthesis in engineered Escherichia coli: jojoba oil-like wax esters and fatty acid butyl esters.
Wax esters are esters of long-chain fatty acids and long-chain fatty alcohols which are of considerable commercial importance and are produced on a scale of 3 million tons per year. The oil from the jojoba plant (Simmondsia chinensis) is the main biological source of wax esters. Although it has a multitude of potential applications, the use of jojoba oil is restricted, due to its high price. In...
متن کاملPhysical Characteristics of Tetrahydroxy and Acylated Derivatives of Jojoba Liquid Wax in Lubricant Applications
Jojoba liquid wax is a mixture of esters of long-chain fatty acids and fatty alcohols mainly C38:2-C46:2. The oil exhibits excellent emolliency on the skin and, therefore, is a component in many personal care cosmetic formulations. The virgin oil is a component of the seed of the jojoba (Simmondsia chinensis) plant which occurs naturally in the Sonora Desert in the United States and northwester...
متن کاملSynthesis and characterization of tetrahydroxyjojoba wax and ferulates of jojoba oil
The new crop oil from jojoba (Simmondsia chinensis) is a skin-softener similar to sperm whale oil. In an effort to find new uses of this oil, we have converted jojoba liquid wax into two new products in mild chemical processes. Tetrahydroxyjojoba wax (THJF) is a colorless, stable, low-melting solid and jojoba ferulate, an ultra violet (UV) absorbing species by esterification of the tetrahydroxy...
