Чувала съм, че думата означава "чрез дима", а не "произвеждащ дима". Та, сигурен ли е превода с производството.--Darsie 06:15, 22 декември 2008 (UTC)Reply[отговор]

Моите нищожни познания по латински ми подсказват, че по-скоро е "чрез дима". Peterdx 06:19, 22 декември 2008 (UTC)Reply[отговор]

В английската и френската Уики също е "чрез дим", поправих го. --Elkost 10:57, 22 декември 2008 (UTC)Reply[отговор]

Since glycerol (1,2,3-propanetriol) is an important component of most lipids, it is necessary to appreciate the full structural nature of this apparently simple molecule. Glycerol contains a prochiral carbon atom linked to H, OH, and two CH2OH groups. When these last two groups are made to differ by attachment to different groups then the molecule becomes chiral and can exist in two enantiomeric forms. To designate the stereochemistry of glycerol derivatives, the three carbon atoms are steospecifically numbered (sn). The glycerol molecule is represented as a Fischer projection with the secondary hydroxyl group to the left of the central (prochiral) carbon atom and the three carbon atoms are designated sn-1, sn-2 and sn-3 from the top downwards (Fig. 3.13). A glyceryl lipid will be chiral when the substituents in the sn-1 and sn-3 positions differ and there will be two enantiomers with different optical rotations (though the difference is often very small). More important is the fact that the enantiomers react differently in enzymic processes. The terms phospholipids (lipids containing phosphoric acid), glycolipids (lipids con- taining one or more sugar units), and sulfolipids (lipids containing a sulfonic acid unit) are loosely used in the way indicated.
