  • The compositions of lipid class and fatty acid of free lipids as non-starch lipid and bound lipids(extraction either at low or high temperature) as starch-lipid extracted from starch in mung bean(phaseolus radiatus L) was investigated. The contents of neutral lipids glycolipids and phospholipids in free lipids were 98.2% 1.7% and 0.1%, whereas those found in bound lipids were 84.3-85.7% 10.5-11.0%, and 5.2-3.3% respectively The major components of neutral lipid fraction in the bound lipids were triglyceride and esterified sterol and those were composed of 0% of total neutral lipids. Monogalactosyl idiglyceride and esteryl steryl glycoside were observed as main glycolipids components in both free and bound lipids. Among the phospholipids in the bound lipids phosphatidylinositol phosphatidyl serine and phosphati-dyl ethanolamine were identified an major constituents. The free lipids contained palmitic(50.2%) stearic(20.6%) oleic(8.5%) and behenic(7.4%) acids and bound lipids had more palmi-tic and linoleic acids but less stearic acid compared to thosed in the free lipids.

  • Twenty five samples of the scheelite-powellite series from twelve Korean tungsten deposits of various geologic settings were studied mineralogically and geochemically. Variations in the trace-element contents of the scheelite minerals are considered in relation to geologic settings and mineralogic properties. Scheelites from ore deposits developed in similar geologic settings and under similar physicochemical conditions are characterized by specific combinations of trace elements.

Effect of Vitamin E and Selenium on the Lipid Composition in Serum and Liver of Rats (비타민E와 셀렌이 흰쥐의 혈청(血淸) 및 간장(肝臟)중의 지질성분(脂質成分)에 미치는 영향(影禦))

  • This experiment was undertaken to investigate ana to compare the effect of vitamin E and selenium on the lipid composition in serum and liver of rats. Net weight gain and food efficiency ratio were elevated by supplementation with selenium and/or vitamin E. The weight of kidney, heart and lung were not affected by the diets. However, liver weight was slightly decreased by supplementation with vitamin E and/or selenium and spleen weight was significantly decreased only by vitamin I supplementation. No differences in serum level of total lipid were found in all groups. Serum cholesterol level was significantly decreased, but the levels of triglyceride and free fatty acid in serum were increased by vitamin E supplementation. Contents of crude lipid, cholesterol, free fatty acid, and triglyceride in liver were significantly decreased by supplementation with vitamin E and/or selenium. In fatty aicd composition of liver, the percentage of linoleic acid(18:2) was the lowest in the selenium-Supplemented group and the significantly lower percentage of arachidonic acid(20:4) was found in the vitamin E and/or selenium-supplemented group in comparision to the deficient basal group.

  • The aim of the study was to investigate the influences of sodium fluoride on the body weight, lipid metabolism functional improvement, blood glucose level, protein component in the sera of rats which fed experimental diets for 5 weeks. Body weight gain of rats was higher in the NF25 group, NF30 group and NF50 group showed a significant difference from the basal diet group (BD group). The changes of the liver and the heart of each argan weights were observed compared to the BD group tends to appear lower in the oral NaF groups (p<0.05). Organ weight of each group of the others showed no significant difference (p<0.05). Serum concentrations of total cholesterol, low-density lipoprotein (LDL)-cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose were lower in BD group than basal diet plus sodium fluoride groups. Conversely depending on the concentration of sodium fluoride for the high-density lipoprotein (HDL)-cholesterol level, it showed lower results. Serum total protein was observed low showed a significant difference in the NF50 group, there was no significant difference in the other groups (p<0.05). globulin and albumin concentration levels also showed the lowest results in the NF50 group.

  • We empolyed gel filtraction, polyacrylamide gel electrophoresis, amino acid autoanalyzer, thin layer chromatography for determining protein and lipid composition in walnut. The walnut contained 22.18% of crude protein and 64.23% of crude lipid. Glutamic acid (38.60%) was the major amino acid in soluble protein, followed by arginine and aspartic acid. The sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis showed 12 band in soluble protein of walnut, and collection rate of main protein fraction purified by Sephadex G-150 was 60.67%. The molecular weight for the main protein was estimated to be 43,000. The lipid fraction obtained by silicic acid column chromatography were mainly composed of about 93.05% neutral lipid, whereas compound lipid was only 7.0% level. Among the neutral lipid by thin layer chromatography, triglyceride was 82.05%, sterol ester and free fatty acid were 3.86% and 4.80%, repectively. The predominant fatty acids of total and neutral lipids were linoleic acid $(64.48{\sim}69.98%)$ and oleic acid $(13.89{\sim}15.36%)$. The major fatty acids of triglyceride separated from neutral lipid were linolenic acid (69.98%).
