RT Journal Article SR Electronic A1 Makovcová, Olga A1 Šindelář, L. T1 Effect of 4-phenethylpyridine on lipid metabolism of mustard seedlings (Sinapis alba L.) JF Biologia plantarum YR 1971 VO 13 IS 5 SP 320 OP 324 DO 10.1007/BF02930919 UL https://bp.ueb.cas.cz/artkey/bpl-197105-0007.php AB Kind of substrate utilized by the respiration of mustard seedlings (Sinapis alba L.) was determined on the basis of found RQ values of control plants. This led to the study of the effect of 4-phenethylpyridine on relationships between lipase, lipoxidase, glycerolkinase and O<sub>2</sub> consumption: Enzyme activities and O<sub>2</sub> consumption rose from the second to the fifth day. According to these results, 4-phenethylpyridine increases degradation of storage fats in the beginning phase of fat catabolism, bringing about advantageous conditions for their metabolic utilization in plant, like in the case of saccharide metabolism.
