Branched chain fatty acids in phospholipids

Branched chain fatty acids in phospholipids. Seyama, Yousuke; Ohashi, Kazumasa; Imamura, Toshiharu; Kasama, Takeshi (Dep.

CODEN: KIMKDN. DOCUMENT TYPE: Journal CA Section: 13 (Mammalian Biochemistry) Lipids were present in the Harder's gland of guinea pigs at 23% of total wet wt. of the gland tissue; phospholipid accounted for 6.9% of the total lipids. Fatty acid compns. of phosphatidylethanolamine (PE), phosphatidylcholine (PC), and cardiolipin (CL) were analyzed. In addn. to the major component oleic acid, a large amt. of satd., branched-chain fatty acids were found: 34.45% in PE, 42.87% in PC, and 73.21% in CL; however, linolenic and arachidonic acids were not found in these phospholipids. These satd., branched-chain fatty acids were not detectable or were present in very small amts. in phospholipids from other organs, indicating that these fatty acids in PE, PC, and CL in the Harder's gland are synthesized by the gland itself. .

Effect of genotype, flowering date, and environment on oil content and oil quality of wild sunflower seed

Effect of genotype, flowering date, and environment on oil content and oil quality of wild sunflower seed. Seiler, Gerald J. (Conserv. and Prod. Res. Lab., Bushland, TX 79012, USA). Crop Sci., 23(6), 1063-8 (English) 1983. CODEN: CRPSAY. ISSN: 0011-183X. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The objective of this study was to det. the influence of genotype, flowering date, and environment on oil content and oil quality of maturing wild sunflower. Thirty-eight populations of wild annual sunflower indigenous to areas from 29° to 46° N Lat and 81° to 122° W Long were planted in a randomized field plant plot design on 12 May 1980. Five heads per population per wk were sibbed or interpollinated, and seeds were collected 28 days later for detn. of oil content, fatty acid compn.There are some reagents with their cas registry numbers 57-10-3 and 112-80-1 are used in this study. of oil, seed wt., and test wt. Flowering date and genotypes (populations) significantly affected all dependent variables. Oil content averaged over all populations increased from the first to last sampling. This is opposite the trend found in com. hybrids. Oleic and linoleic acid concns. of the oil decreased and increased, resp., for later flowering dates. Oleic and linoleic acids began at lower and higher levels, resp., in the wild sunflower compared to the com. hybrid but all were about the same concn. at the last samplings. Based on multiple regressions, daylength and Julian day significantly influenced oil content. Linoleic acid was significantly influenced by Julian day, total solar radiation, and max. temp., whereas, oleic acid was influenced only by the latter 2 factors. Oil content and linoleic acid concn. differed significantly in seeds of the original population vs. the seeds grown at a single location. Sibbed and open-pollinated seeds did not differ in total oil content when grown at a single location, but linoleic acid did. Oleic acid concns. of sibbed and open-pollinated seeds of populations grown at a single location did not differ significantly from the seeds of the original populations. .
