Treatment of O-acyl lipids with hydrazine degrades them to hydrazides of the constituent fatty acids. These hydrazides react with acetone to yield less polar and more volatile N'-isopropylidenealkanohydrazides, R-CO-NH-N = C(CH3)2, which strongly absorb ultraviolet light and are amenable to thin-layer and gas-liquid chromatographic analyses. In presence of cyclopentene, reduction of double bond...
PACKETT, L. V. (Purdue University, Lafayette, Ind.), AND R. W. MCCUNE. Determination of steam-volatile organic acids in fermentation media by gas-liquid chromatography. Appl. Microbiol. 13:22-27. 1965.-Five gas chromatographic liquid phases (25% Carbowax 20M plus 4% H3PO4, 17.5% dioctyl sebacate plus 7.5% sebacic acid, 17.5% dioctyl sebacate plus 7.5% docosanoic acid, 5% Tween 80, and 20% LAC29...
Infant formula has a fatty acid composition that meets the needs of the neonates for unsaturated fatty acids.These fatty acids are of major importance during this period of life in which the brain and retina are developing, and will therefore have an influence upon visual acuity and learning abilities. Oxygen reacts readily with unsaturated fatty acids, so that every time these compounds are ha...
زئوپلانکتون¬ها گروه بسیار مهمی از موجودات زنده بوده که پایه زنجیره غذایی را در اکوسیستم¬های آبی تشکیل می¬دهند. از بین آن¬ها کلادوسرها و کپه¬پودها نقش مهمی را در زنجیره غذایی آبها داشته و از طریق تغذیه روی انواع موجودات زنده آبزی، انرژی را از میکروالگ¬ها به سطوح بالای هرم غذایی انتقال می¬دهند. همچنین زئوپلانکتون¬ها منابع ارزشمندی از پروتئین¬ها، اسیدهای آمینه، لیپیدها، اسیدهای چرب، ویتامین¬ها و آ...
Background and Objectives: Breast milk composition is affected by several factors such as maternal diet and body mass index. Milk fats include a major calorie content of the milk, which changes dramatically throughout the lactation. The aim of the present study was to assess breast milk fatty acid profile in overweight and obese mothers and its correlations with maternal body mass index. Mater...
