The analysis of commercial lecithin

“…Decant the s o h through a No. 4 Whatman filter paper into a 400 ml flask. Evaporate the residual acetone from the insol.…”

“…Filter the combined aqueous layer through a fluted Whatman No. 4 filter paper into a 600-ml conical flask. Use the third and fourth extracts from the lecithin-petrol solution to wash the petrol in the second separator and the filter.…”

Hydrobiological Aspects of Saturated, Methyl-Branched, and Cyclic Fatty Acids Derived from Aquatic Ecosystems: Origin, Distribution, and Biological Activity

“…Typically, FA are carboxylic acids with aliphatic chains of various lengths: short chain (C1-C7), medium chain (C8-12C), long chain (C13-C22), and very long chain (C24-C36). The most common FA chain length range is between C14 and C20 [1, [4][5][6][7][8][9][10][16][17][18][19][20][21][22][23][24][25]. During digestion, the body breaks down dietary fats into FA, which then enter the bloodstream.…”

“…FA molecules combine in groups of three FA to form a molecule called triglyceride [15]. Complex lipids are the basis of the biological membranes of marine organisms, algae, plants, fungi, animals, and microorganisms [1- 3,[5][6][7][8][9][10][11][12][17][18][19][20][21][22]. The biochemistry and chemistry of FA are well studied, made up of aliphatic chains that contain a carboxyl group (-COOH) [1,2].…”
