A resonant photoacoustic heat-pipe (PAHP) cell was constructed and used for spectral studies of four long-chain saturated fatty acids (C10:0 to C16:0) at CO laser wavelengths and temperatures above that of the ambient. Vapor-phase absorption spectra were recorded at temperatures of 383 K for capric acid C10H20O2, 400 K for lauric acid C12H24O2, 438 K for myristic acid C14H28O2, and 445.5 K for palmitic acid C16H32O2, respectively. In addition, the temperature dependence (298 to 393 K) of vapor pressure was determined for C10:0; measurable PA signals were obtained at a temperature only a few degrees above the melting point for this acid. The data observed for C10:0 could be linearly fitted from as low as 323 K, indicating the validity of the Clausius-Clapeyron equation for temperatures lower than the 398 K < T < 541.4 K range anticipated so far.

(1) Long chain carboxylic acids dissolved in benzene show regular changes in interfacial tension against aqueous "buffered" solutions as the hydrion concentration of these is altered. A fall in interfacial tension starts at p h 5·5 and extends over the range of 4·0 p h 9·3 approximately, tending to vanish at this point. The curve is not identical with a dissociation curve, though it extends over the same range of p h . For a given p h the results are identical for phosphate and glycine "buffered" solutions, and for all acids investigated, except capric acid(C 10 ), which shows an abnormality for phosphate. (2) Hexadecylamine shows similar changes, in the opposite sense between approximately the same p h range, which follow the dissociation curve of a weak base rather closely

Long Chain

Embryos of Cuphea lanceolata have more than 80 mol% of decanoic acid (‘capric acid’) in their triacylglycerols, while this fatty acid is virtually absent in phosphatidylcholine (PtdCho). Seed development was complete 25-27 days after pollination, with rapid triacylglycerol deposition occurring between 9 and 24 days. PtdCho amounts increased until day 15 after pollination. Analysis of embryo lipids showed that the diacylglycerol (DAG) pool consisted of mainly long-chain molecular species, with a very small amount of mixed medium-chain/long-chain glycerols. Almost 100% of the fatty acid at position sn-2 in triacylglycerols (TAG) was decanoic acid. When equimolar mixtures of [14C]decanoic and [14C]oleic acid were fed to whole detached embryos, over half of the radioactivity in the DAG resided in [14C]oleate, whereas [14C]decanoic acid accounted for 93% of the label in the TAG. Microsomal preparations from developing embryos at the mid-stage of TAG accumulation catalysed the acylation of [14C]glycerol 3-phosphate with either decanoyl-CoA or oleoyl-CoA, resulting in the formation of phosphatidic acid (PtdOH), DAG and TAG. Very little [14C]glycerol entered PtdCho. In combined incubations, with an equimolar supply of [14C]oleoyl-CoA and [14C]decanoyl-CoA in the presence of glycerol 3-phosphate, the synthesized PtdCho species consisted to 95% of didecanoic and dioleic species. The didecanoyl-glycerols were very selectively utilized over the dioleoylglycerols in the production of TAG. Substantial amounts of [14C]oleate, but not [14C]decanoate, entered PtdCho. The microsomal preparations of developing embryos were used to assess the acyl specificities of the acyl-CoA:sn-glycerol-3-phosphate acyltransferase (GPAT, EC 2.3.1.15) and the acyl-CoA:sn-1-acyl-glycerol-3-phosphate acyltransferase (LPAAT, EC 2.3.1.51) in Cuphea lanceolata embryos. The efficiency of acyl-CoA utilization by the GPAT was in the order decanoyl = dodecanoyl greater than linoleoyl greater than myristoyl = oleoyl greater than palmitoyl. Decanoyl-CoA was the only acyl donor to be utilized to any extent by the LPAAT when sn-decanoylglycerol 3-phosphate was the acyl acceptor. sn-1-Acylglycerol 3-phosphates with acyl groups shorter than 16 carbon atoms did not serve as acyl acceptors for long-chain (greater than or equal to 16 carbon atoms) acyl-CoA species. On the basis of the results obtained, we propose a schematic model for triacylglycerol assembly and PtdCho synthesis in a tissue specialized in the synthesis of high amounts of medium-chain fatty acids.

The physicochemical properties, fatty acid composition, aflatoxin contamination and heavy metals of extracted mango kernel oils of four Bangladeshi varieties (Langra, Gopalbhog, Khirshapat & Amrupaly) were studied. The results were compared with published values of ‘CIR expert panel’, ‘Indian Standard of Mango Kernel Fat’, ‘Scientific Commission of the European Community’ and ‘US Food and Drug Administration (FDA)’. The estimated values of aflatoxin B1and total aflatoxins were 1.45809 ppb and 5.14761ppb respectively which were lower than the limit levels of ‘European Community (2 ppb for aflatoxin B1)’ and ‘US FDA (20ppb for total aflatoxins value)’. Heavy metals like arsenic & lead concentration were found 0.034 & 0.45 ppm respectively which were lower than the value of ‘Indian Standard of Mango Kernel Fat; 9231 (1979)’ (0.5 & 5.0 ppm respectively). In fatty acid composition; palmitic acid, stearic acid, arachidic acid, oleic acid and linoleic acid were within the range of ‘CIR expert panel’ reported values.Bangladesh J. Sci. Ind.
