Identifying the Presence of Macromolecules Using Benedict’s, Biuret’s, Sudan III, and Lugol’s Solution Betty Ngo Introduction Macromolecules are the critically important large molecules that fall into four main classes: carbohydrates, lipids, proteins and nucleic acids. Macromolecules are polymers which are built up by monomers. Monomers become polymers from the process dehydration reaction and polymers are broken apart by the process hydrolysis. Macromolecules are critically important…

Jeannette Walls. The memoir consists of the struggles and the big adventure Jeannette Walls had in her childhood traveling to many cities with her family. Coming from living in numerous cities and living in poverty with her family at such a young age, Jeannette Walls shows how difficult her childhood was. No matter how tough the situation she was in or what actions she took, Walls talks about how she was able to get through her struggling childhood and grow to have a successful life. Jeannette…

Rebecca Chua 10 Honors Summer Assignment: The Glass Castle by Jeannette Walls  “Like build the Glass Castle. All of Dad’s engineering skills and mathematical genius were coming together in one special project: a great big house he was going to build for us in the desert. It would have a glass ceiling and thick glass walls and even a glass staircase… All we had to do was find gold, Dad said, and we were on the verge of that. Once he finished the Prospector and we struck it rich, he’d start…

space for 5 years while cleaning robots ("WALL-Es" invented by Professor Simon) prepared Earth for recolonization. However, after seven hundred years, only one WALL-E (voice: Ben Burtt) remains. WALL-E spends his days compacting debris into solid blocks…

Aquaporins are a family of membrane proteins that selectively conduct water molecules in and out of the cell, while at the same time preventing the passage of ions and other solutes. They can be found in animal, bacteria, and plant cells. So far 13 Aquaporins have been discovered (AQP0-AQP12) some of the Aquaporins only transport water molecules, such as AQP1, AQP2, AQP4, AQP5 and AQP8. Aquaporins that transport water and other solutes are called aquaglyceroporins, these can transport glycerol,…

lipopolysaccharide, surface protein, outer membrane, lipoprotein, peptide glycan, and cell membrane. These two are mainly composed of a lot of different materials and have just a few of the same materials but are in different placements. The thicker the cell wall than the more it will be able to dissolve. The reason why is due to the N+ strong affinity to water which is known to be hydrophilic. The R which is the alkyl is the opposite of being water loving and instead is hydrophobic. This…

It is expected that if the concentration of sucrose increases from 0.0 M, 0.2 M, 0.4 M, 0.6 M and 0.8 M (±0.01 g) in a 40 (±0.5) mL sucrose solution, then the average percent change in mass in Solanum tuberosum core will decrease. This is because if the Solanum tuberosum cores are placed in a hypotonic sucrose solution, which is described as having lower osmolarity, than the percent change in mass of the Solanum tuberosum core will increase due to the fact that water molecules will be moving…

The genetic combinations; two normal genes, one normal and one cystic fibrosis, and two cystic fibrosis, each affect the membrane proteins involved in transporting chloride ions through the cell membrane. Two normal genes would not alter whether or not the membrane proteins would correctly shield the chloride ions so that the ions could pass through the cell membrane. With this ability of the chloride ions successfully transporting across the cell membrane the body would not generate a…

class and you better learn how to swim meant to me that if you are losing money you should do something about it. The Walls family is a poor family but they make the best of it. When the parents don't have jobs the kids help by doing things like yard work for a neighbor of collecting rocks to sell. When the grandmother died they got some of her money which was a upbringing. But the Walls don't really know how to save money so they spend it on useless things like art supplies and beer. When they…

Amoxicillin is an beta lactam aminopenicillin that inhibits bacterial cell wall synthesis by binding to penicillin binding protein and blocking transpeptidation. It has low protein binding and is eliminated renally and mostly unchanged. It has a beta lactam ring, an absolute configuration of 2S, 5R, 6R, a carboxylic acid group at C2 position and an amide bond at the C6 position. It has broad spectrum activity and can be used against gram negative bacterial infections. Erythromycin is a…
