26% of the all volatiles, and carboxylic acids for ca. 18%. Small amounts of alcohols, toluene, and phenol were also found. In a sensory test of the odor from the mixed solution of identified compounds, the odor was found to resemble the off-odor of the irradiated polyethylene....
3 insert). Most flavor chemicals were esters, and many were terpenes, phenols, alcohols, ketones, and aldehydes. The “other” category included benzopyrone, pyrazine, pyrone, and thiazole. While not shown in Fig. 3, some chemicals belong to more than one class, such as vanillin, which is...
of alcohols, thioalcohols, alkyl phenol, fatty acids, polyoxyethylene polyoxypropylene acids, sorbitan fatty esters, fatty amides, polyoxyethylene glycols (PEG) condensates. In addition, individual members of a class can be separated and identified. The method is applicable to a variety of detergent ...

3-Ketosteroid-Δ1-dehydrogenase (KstD) is a key enzyme in the metabolic pathway for chemical modifications of steroid hormones. Only a few KstDs have thus far been characterized biochemically and applied for the production of steroidal pharmaceutical int
The sample LS232 seems to be a mixture of scammony resin, fatty acids (vegetable oil with unsaturation) and fatty alcohols (all compounds identified are listed in Table 2). On the other hand, LS223 sample is a very complex mixture of “ladano” resin, a characteristic marker of Venetian...
