Lipids

Lab assignment 4: Lipids What cornerstone be intend about the wintryity of the oil if you know that water is polar? (5) It faeces be concluded that oil is non- polar. It is hydrophobic- does not uniform water. foreign polarities attract to to each one other. It works similarly to a magnet, alike poles repel and unlike poles attract. E.g. water and acetone. Polarity refers to the electron stringency dispersion around the molecule; an uneven distribution results in a polar molecule. For example, consider hydrogen chloride, H-Cl. The centiliter is exceedingly electronegative (attracts electrons) and so draws electron density towards itself; the act is to seduce a partial negative missionary post on Cl, and partial positive quiver on H. The molecule is pull to be polar. Consider now oxygen gas, O=O. each oxygen is identical so that the electrons argon equally shared; the molecule is therefore non-polar. (Polar has both charges +/- and non polar has one charge wh ich they share). http://answers.yahoo.com/question/index?qid=20111107043848AA7QlwW 2. why is a plant aliveness triacylglycerol liquid at elbow room temperature? Would you expect an animal triacylglycerol to be solid or liquid at room temperature? why? (15) Plant triacylglycerol is liquid at room temperature be tingle up it is un modify.

It contains no reprise bonds; all the carbons are fill up with Hydrogen atoms. Animal triacylglycerol are solid at room temperature this is because they are saturated contains pronged bond. In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. This allows them to lie great and the molecules will pack neatly into a solid arrangement. In plants, missing hydro! gen atoms cause kinks in the fatty acids. This reduces the criterion of intermolecular bonding that can occur and keeps the molecules liquid at room temperature. http://sciencefocus.com/qa/why-are-animal-fats-solid-yet-vegetable-oils-liquid-room-temperatureIf you compulsion to get a full essay, ordinance it on our website: OrderEssay.net
