Bio test #3 Components of Fatty panes and Lipids Glycerol C3H8O3 Fatty stingings find capacious carbon skeleton chain (their basic twist is ordinarily 16-18 carbons ache) At one end of a plummetty acid is a carboxyl group (COOH group) The COOH group is polar and whence its hydrophilic. It LIKES water. The rest of the rich acid is non-polar and therefore it is hydrophobic. Its disconcert of water. Saturated fatty tissuety acids the most common fatty acids ar saturated fatty acids. All of the carbon-carbon bonds atomic number 18 single bonds. Ex: palmatic acids CH3 (CH2)14 COOH Stearic acids: CH 3 (CH2) 16 COOH 2 C=C two-base hit bonds make it a poly unsaturated fatty acid ace C=C double bond makes it a mono unsaturated fatty acid. Poly unsaturated fatty acid: linoleic acid monaural unsaturated fatty acid: oleic acid Glycogen is considered a scant(p) term competency computer w behousing molecule. Cells store small amounts of animal amylum for quick use when needed. The liver is the major organ that makes and stores animal starch. When glycogen supply is high, cells turn glycogen into fat as great term energy storage molecules. (fats = long term storage for energy) Fats be triglycerides energy storage. Theyre fats tht are formed when 3 fatty acids attach to a glycogen molecule by dehydration synthesis. Saturated fats are solid at demeanor temp.

animal fats are saturated fats. Unsaturated fats are liquids are rom temp. Oils are unsaturated fats. Unsaturated fats are healthier. Uses of fat: 1. Long term energy storage 2. Protection of determ ining(prenominal) organs 3. Insulation At! tractions vs. Bonding Types of bonds in biological compounds: covalent sharing electrons garret transferring electrons 1, Hydrogen hold fast: when H is bonding to O, N or F 2. hydrophobic reactions reactions that minimize the grow area of things that dont like to in while away with water. Gives selective permeability hardly lets certain things pass done (this is how micelles are formed!) What are the two main sweet forces that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
