Components of Fatty panes and Lipids
Glycerol C3H8O3
Fatty acids have capacious carbon skeleton chain (their basic structure 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 accordingly its hydrophilic. It LIKES water.
The rest of the fatty acid is non-polar and therefore it is hydrophobic. Its unnerved of water.
Saturated fatty 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
Two C=C double 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 energy computer storage molecule. Cells store small amounts of animal starch for quick use when needed. The liver is the major organ that makes and stores glycogen. When glycogen supply is high, cells turn glycogen into fat as long 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 fashion 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 decisive organs 3. Insulation
Attractions vs. Bonding
Types of bonds in biological compounds:
Covalent sharing electrons
garret transferring electrons
1, Hydrogen bonding: when H is bonding to O, N or F
2. hydrophobic reactions reactions that minimize the surface area of things that dont like to in contact with water. Gives selective permeability hardly lets certain things pass through (this is how micelles are formed!)
What are the two main attractive forces that...If you want to get a full essay, order it on our website: Orderessay
