A glycosidic linkage can consist of disaccharides, oligosaccharides or polysaccharides. Disaccharides are single glycosidic linkages between two monosaccharides, while a oligosaccharides are multiple glycosidic linkages that are often times covalently bonded to proteins and lipids. However, a polysaccharide is a large polymer of monosaccharides that are also connected by glycosidic links yet they are not exactly linear since each unit has several sites that are capable of forming linkages. In organisms lipids store energy in the C-C and C--H bonds, play important structural roles in cell membranes and body surfaces since they are non polar meaning they are insoluble in water and lastly the fat in animal bodies serve as thermal insulation. Phospholipids are amphipathic because they partly hydrophilic and hydrophobic.  The phospholipids form a lipid bilayer membrane since the phosphate functional group has a negative charge so the hydrophilic portion attracts polar water molecules meaning that in an aqueous environment, phospholipids would line up where the tails which is the non polar or hydrophobic portion is packed tightly to the polar or hydrophilic portion when they interact with water forming a lipid bilayer membrane.]]> 2020-10-17 04:40:00 UTC https://padlet.com/mslecour/37wrqaeqlbja6voo/wish/837371519 kleonce6152 https://padlet.com/mslecour/37wrqaeqlbja6voo/wish/841281201 Four major roles of carbohydrates are to provide energy for the body, store energy, build macromolecules, and spare protein and fat so they can be used for other things. One example of a glycoside linkage is monomers linking together to form a disaccharide. Lipids roles in living organisms is to store energy for the body. Phospholipids are amphipathic because they have a phosphate to replace on of the fatty acids which causes them to hydrophobic and hydrophilic.

The four major roles of carbohydrates are that they provide energy for organisms,they store energy, store fats and build up macromolecules. An example of a glycosidic linkage is when the monosaccarides glucose and fructose come together to form the disaccharide sucrose. 3 roles of lipids in living organism is storing energy in their cc and ch bonds. They serve as thermal insulation in animals. Lastly they have important structural roles on body surfaces and cell membranes. Phospholipids are amphipathic because they have an end thats hydrphobic and an end thats hydrophillic. This results in a bilayer membrane because the ends will create bonds with what theyre attracted to and will have a layer because the hydrophobic side will not mix with water so theirs a layer in between both ends.]]> 2020-10-20 02:28:02 UTC https://padlet.com/mslecour/37wrqaeqlbja6voo/wish/843356521 lcalle975 https://padlet.com/mslecour/37wrqaeqlbja6voo/wish/847193766 the four major roles of carbohydrates are that they give energy for living organisms, they save energy, store fats and build up macromolecules.

- 'They stored energy"
- "They're used to transport stored energy" 
- "They function as structural molecules"
( page 27 )
- They serve as recognition or signaling molecules
2) One example of a glycosidic linkage is a Oligosaccharides this glycosidic linkage are covalently bonded to proteins and ;lipids on the outer surface of the cells. They're there to serve as  recognition signals.
3) Three roles of lipids in living organisms is:
- "They store energy in the C-C and C-H bonds"
- "They play very important structural roles in the cell membrane as well as body surfaces, because their non polar nature makes them insoluble to water." 
- "Fat in animal bodies serves as thermal insulation"
( page 29 )
4) Phospholipids are amphipathic because it contains partly hydrophobic and hydrophilic. This results as a lipid bilayer membrane because phospholipids line up that the non polar, hydrophobic "tails"  pack tightly together & the phosphate the contains the " heads"
this is where they interact with water.

Glycosidic linkages are monosaccharides that are covalently bonded through dehydration synthesis to form disaccharides, oligosaccharides, and polysaccharides. Disaccharides are single glycosidic linkages between two monosaccharides. Oligosaccharides are glycosidic linkages with several monosaccharides. Polysaccharides are large polymers of monosaccharides connected by glycosidic linkages. Lipids store energy in carbon to carbon and carbon to hydrogen bonds, play important structural roles in cell membranes and on body surfaces, and the fat in animal bodies serves as thermal insulation. Phospholipids are amphipathic because they are partially hydrophilic and partially hydrophobic, the head of the fatty acid is hydrophilic and the tails are hydrophobic. This forms a bilayer membrane because the phospholipids line up in a way that the hydrophilic head which has a negative charge will face outward in an aqueous solution and attract polar molecules and the tails which are hydrophobic avoid water and tend to aggregate together.]]> 2020-11-20 06:59:17 UTC https://padlet.com/mslecour/37wrqaeqlbja6voo/wish/944479133
