the lipids and cram them inside the spheres. The outside portion of the sphere ishydrophilic and they interact with the water in our plasma thus transporting the lipidsaround our body.30. Amphipathic molecules are key in transporting hydrophobic substances around the body(example: LDL or HDL are amphipathic molecules and they carry cholesterol and fat.HDL “the good cholesterol” because it carries to the liver to be destroyed, LDL “the badcholesterol” takes the cholesterol and stores them to cells, LDL (low density lipoprotein)it is an amphipathic molecule and not considered a cholesterol, it contains cholesterolwithin them. HDL (high density lipoprotein)31. Dehydration Synthesisa.Water is lost in the dehydration synthesis, also known as condensation reaction32. Polysaccharidesa.Starch, Glucose, and celluloseb.Starchb.i.Two forms by amylose and amylopectinb.ii.20% is amylose 80% amylopectinc.We store glucose as glycogen and plants store glucose as starchd.Dietary fibers for us would be cellulosee.Fibers make poop more bulky making the large intestines contract moreexcluding more muscle strength thus making them work33. Fatty Acidsa.Do dehydration synthesis to make fatty acidsb.Hydrolysis to break down the fatty acids34. Phospholipidsa.Micelle structurea.i.ex. phospholipid lipids are detergent, micelles form and trap the dirt,grease and grime
a.ii.Mix phospholipids with water to make micelles35. Cholesterola.Cholesterol is a lipidb.Parent compound for steroid moleculesc.Steroids are derivate of estrogen and testosteroned.Vitamin D is a steroid hormone produced from cholesterold.i.Expose skin to sunlight and there is an enzyme that activates andconverts cholesterol to vitamin De.Testosterone and estrogen are anabolic hormones36. Lipidsa.Bile acids are steroids, made up of phospholipids and cholesterol, they areessential for properly digesting fat.b.Fat soluble vitaminsb.i.A, D, E, and K (vitamins)b.ii.Plays a role in the absorption of fatc.Triglycerides, we store glucose as glycogen, we also store fat in fat cells, fat iscaloric, why?, there are more carbon bonds so it is easier to break as opposed tocarbohydrates, breaking bonds using for energy.d.Proteins you get 4 calories per gram, carbs 4 calories per gram, fat as 4 calories,and alcohol as 7 calories per gram.e.Energy usage order: carbohydrates, then lipids, then proteins (from muscles andthen break it down in the liver to take the glucose)f.The most abundant tissue in your body is the skeletal muscle, so when theskeletal muscle is at rest, they need cellular respiration to survive so they use thefat in our body to get the energy to do so.37. Amino Acidsa.N terminus (nitrogen at the end), Amino groupb.C terminus (carbon at the end), Carboxylic acid groupc.R group, the function group, the group that makes the amino acids a difference
