Introduction
Chemistry education is aimed at preparing one for better living. Chemistry occupies a central position among science subjects. Chemistry is conceptualized as gaining knowledge problem-solving and constructing personal understandings.
Chemistry can be defined as using our knowledge of how matter is put together and how it interacts with other matter to solve confusing problems.
What are linseeds?
Linseed and camelina are ancient crops containing seed oils with a high potential for nutritional, medicinal, pharmaceutical, and technical applications.
Analysis of Triacylglycerols from Linseed by Lc-Ms3
In the present study, linseed and camelina oils of plant varieties grown under Central European climate conditions were examined concerning their volatile and triacylglycerol (TAG) components (Bogomolova et al, 2004). Solid-phase microextraction was applied to the study of volatile compounds of several linseed and camelina oils, which have not been described before this publication. Hexanol (6.5-20.3% related to the total level of volatiles), trans-2-butenal (1.3-5.0%), and acetic acid (3.6-3.8%) could be identified as the main volatile compounds in the linseed oil samples. Trans-2-butenal (9.8%) and acetic acid (9.3%), accompanied by trans, trans-3,5-octadiene-2-one (3.8%) and trans,trans-2,4-heptagonal (3.6%), dominated the headspace of the examined camelina oil samples. TAG was analyzed by MALDI-RTF-MS and ESI-IT-MS, providing information about the total TAG composition of the oils as well as the fatty acid composition of the individual components (Bogomolova et al. 2004). More than 20 TAG could be identified directly from whole linseed oil samples, mainly composed of linolenic (18:3), linoleic (18:2), and oleic (18:1) acid, and to a lesser degree of stearic (18:0) and palmitic (16:0) acid (Lobert, 2004). While in linseed these tags comprise more than 60% of the oils, Camelina sativa exhibited a wider range of more than 50 constituents, with a considerable amount (>35%) of TAG containing gadoleic (20:1) and eicosadienoic (20:2) acid (Bates, 2009).
The reactions leading to triacylglycerol (TAG) synthesis in oilseeds bed been advisably characterized. Still, numeric analyses of radical meet and alcohol grit fluxes that comprise extraplastidic emulsifier and TAG synthesis, including group writing and phosphatidylcholine-diacylglycerol interconversion, are nonexistent. To canvas these fluxes, we apace tagged processing soybean (Glycine max) embryos with [14C] dyestuff and [14C] alcohol.
Cultured integral embryos that process in planta growth was utilized (Cautisan, 1998):
Most 60% of the newly synthesized fat acids opening enter glycerolipids through PC radical writing, largely at the sn-2 lieu. (Heacuteron et al.1995).
This mix, mostly of oleate, was over iii present the denseness of nascent [14C] greasy acids incorporated into the sn-1 and sn-2 positions of DAG through glycerol-3-phosphate acylation (Lodgsdon, 1994). Furthermore, the adipose resolvent reasoning (Philip et al, 2009).
Borage oil is a gripping oil because it is affluent in navigator linolenic Elvis (. Ln 18:3 Z6, Z9, Z12). Yet, since triacylglycerol standards with. Ln chains do not subsist, there is difficulty identifying these special triacylglycerols (MaDkowski et al, 2000).
Because the hyphenated techniques (GC-MS, LC-MS) do not resign adequate adjudicate for reasonable finding, an easier process is discussed here.
It consists of using other oil of notable property as a definitive arm. Use this process is usually used for the duty of triacylglycerols in borage oil.

Result
As a result, recycled acyl groups (16:0, 18:1, 18:2, and 18:3) in the acyl-coenzyme A water endow with most of the radical chains for de novo glycerol-3-phosphate acylation (Cautisan et al., 1998).
Our results also state as defined DAG pools .

Conclusion
Molecular species of triglycerides (TG) were determined in vegetable fats and oils, both qualitatively and quantitatively by capillary action, Gas chromatography (CGC) on a polarizable column, reversed-phase C18 High-Performance Liquid Chromatography (RP-HPLC), and desorption chemical ionization mass spectrometry (DCI-MS).
The determination of CGC and part of RP-HPLC not only with Oils with either a complex distribution of chain lengths, ie, linseed oil and black currant oil.
