sample of cholesterol; the test is specific to 5α- or △5-steroids having a double bond adjacent to C14. A simple method for isolation of ketone 104 and cholestanone involves a novel phase-separation method for working up a dichromate oxidation mixture and a separation based on the fact ...
The new procedure was used to detect 6-ketocholestanol in fresh, unirradiated chicken and measured more than 97% of the test compound added to chicken below the ppm level. Irradiation of the chicken meats to a dose of 10 kGy increased the concentration of this compound to about four times...
Results of this test confirm previous proposed membrane interactions by skin diffusion studies. Additional differential scanning calorimetry studies with 1,2-dimyristoyl- sn-glycero-3-phosphocholine (DMPC) and 1,2-dipalmitoyl- sn-glycero-3-phosphocholine (DPPC) liposomes confirm a membrane interaction ...
