Unsaturated compounds, marine organic

The total alkane contents in vegetable oils ranges from about 10 to 200 mg/kg. Their amount in sunflower oil is 105 170 mg/kg, and in oHve oil approximately 30-100 mg/kg. The amount of alkanes in the cuticular wax of apples, for instance, is about 33% of the Hpid accompanying substances. About 97% of all hydrocarbons in the cuticular wax are represented by nonacosane ( 79), about 2% by heptacosane ( 77) and the remaining 1% consists mainly of alkanes 75, 78, Cjq and Cjj. The cuticular wax of grapefruits is composed primarily of oxygenated compounds, while the content of alkanes is only around 1%. Fats of marine organisms (e.g. fish Hver oils) contain saturated and unsaturated hydrocarbons Cjg and Cj7 or Cji as the main components. The total content of alkanes is about 10-30 mg/kg.
