Biology: The Chiral Molecules Essay

This section will dealt with the main organic molecules in living things: carbohydrates, fats ( lipids ), proteins and nucleic acids.

Carbon has unique properties that allow macromolecules to form. One is that carbon can form four covalent bonds. This is because of the four valence electrons it has. A carbon atom can have a triple bond with one atom and still have an extra electron to share with another atom. Carbon bonds can take on different shapes: linear, branched, or ring-shaped. Carbon also bonds with functional groups. Functional groups are molecules with unique chemical characteristics and properties. These include hydroxyl and phosphate groups. Carbon containing molecules can have multiple forms. These different forms are called isomers. These different molecules can have the same molecular formula but will have different shapes and characteristics. Structural isomers

While doing this exercise I realized that I know the basics about food such as how carbohydrates, fats proteins are necessary and how they affect the body but I never knew what the macromolecules did in depth. I also learned what the macromolecules did in depth. I additionally learned that they are called macromolecules and that macromolecules are sizably voluminous organic molecule composed of more minute organic molecules composed of 95 percent carbon hydrogen nitrogen oxygen used to fortify our bodies .the other 5 percent gives the macromolecule unique qualities.

Promising materials for nanofibrous scaffolds include poly (ɛ-caprolactone) (PCL) in combination with gelatin because electrospun PCL closely resembles the ECM and gelatin is a natural biopolymer with biodegradable and biocompatible properties. Previous studies in the field of tissue engineering have focused on the biological properties and biocompatibility of NGCs, but little work has been done to study the biomechanical properties of NGCs and how they compare to native peripheral nerve tissue in vivo. This is an important area of study because the NGCs must be sufficiently elastic to avoid tension at the injury site, but cannot collapse due to the patient’s movements [7]. Designing NGCs with favorable mechanical properties is necessary for successful axonal growth and nerve regeneration. This research will provide a better understanding of the mechanical properties of peripheral nerve tissue and NGCs as well as develop a method to test the performance of NGCs in

You refer to my home planet as Chiron, a fairly large planet located in the Boötes constellation. My home planet has been invaded, stripped of anything valuable. My species is almost extinct. 10 of us and our Trainers escaped to Earth. We weren’t forced to leave Chiron because of corruption, or overpopulation. We left because of our the neighboring planet named Tartarus. I can’t quite remember how life was before The Cleansing mostly because I was merely a two year old toddler, but one thing that I do remember, was that Chiron was beautiful, very large forests, beautiful wildlife, and at least twice the size of this puny planet, “Earth”. I miss home sometimes, though I have a hard time remembering what it was like before The Cleansing. I do remember before the escape pods left orbit my father told me, “Carry on our legacy son, whenever you’re scared, think of me, your brothers, and your mother. We will be with you forever. Be brave.” and still to this day I do that. He kissed my forehead, then we took off for our next destination, Earth, a year in travel.

All living things are made out of billions of cells and all contain macromolecules. They are responsible for life as we know it. As we begin to advance and go farther in the field of science, more and more questions are being asked and to answer them, more technologies and techniques are being created and discovered. Scientists John B. Fenn and Koichi Tanaka (for mass spectrometry, a method of identifying molecules) and Kurt Wüthrich (for nuclear magnetic resonance, a method used to form a three-dimensional image of a molecule) created different methods that allowed us to embrace macromolecules. They created a revolutionary breakthrough that made chemical biology into the “big science” of our time.

We continue walking for many days. Nothing bothered us and Chiron kept telling me that we were getting close.

There are four macromolecules present in a living organism. The first one Carbohydrates. Carbohydrates are also known as sugars, they are the major source of energy for daily activities. Proteins are the second macromolecules present in living organisms. Proteins are used in the process of a cell's structural components proteins are important to the structure of the cell’s membrane and they make up half of the dry weight in most cells. Lipids are the third presence in a living organism. Lipids are a type of organic molecule, and they are abundant in living organisms. Fat is one kind of lipid, they are hydrophobic and their function is to store energy in the organism. The last one is Nucleic acids. They are composed of nucleotides. Nucleotides

The book Chimera by John Barth is not one but three books all taking places in different places and times in Greek mythology. The book is split into three part the Dunyazadiad, the Perseid, and the Bellerophoniad. Just as in the Aeneid the main characters names are in each of the section titles: Dunyazade, Perseus, and Bellerophon. Their stories are literally just simple retellings except told from other points of view to give another point of view as if we are seeing it from the worlds point of view instead of the heroes.

The four types of macromolecules in living organisms are; carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are our bodies’ energy boosters so that we can tackle our daily routines. The ring-shaped objects that are referred to as the building blocks of carbohydrates are called monosaccharides. Glucose, galactose, and fructose are well-known monosaccharides (Daempfle, 2016). Lipids exist as neutral fats, phospholipids, and steroids that are contained in fat cells to be utilized as extended duration storage of energy. Lipids are similar to carbohydrates but with increased amounts of carbon and hydrogen. Proteins are the predominant of all the macromolecules in living systems. They are an instrumental part of our bodies that consist

A compound action potential is the sum of electrical activity produced by all the individual neurons in a nerve that are brought to a critical membrane potential by a local stimulus. This critical membrane potential, referred to as threshold potential, is needed to be reached during depolarization to elicit an action potential. Two sub-threshold potentials occurring in quick succession can summate and cause an action potential to occur even though each individual potential would not trigger an action potential. This is referred to as temporal summation. After the depolarization phase of the membrane, the membrane becomes completely unresponsive to stimulation, known as an absolute refractory period. The speed at which an action potentials are

The present scenario, the demand in the medical diagnostics has grown for the simple and disposable devices that also have seen fast response times, are user-friendly, cost efficient, and are most important suitable for mass production.Biosensor technologies has the potential to fulfill all these criteria by the help of an interdisciplinary combination of approaches from nanotechnology, chemistry and medical science and physics .

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.

The purpose of this lab was to test for macromolecules consisting of starch (carbohydrates), lipids, proteins, and nucleic acids. Testing for the macromolecules occurred by using specific reagents on each macromolecule. If a color change occurred, then the sample would prove to be positive for that macromolecule. For simple sugars, the Benedicts solutions was used as the reagent; for starches, the iodine solution was used as the reagent; for lipids the Sudan III solution was used as the reagent; and for the proteins, the Biurets solution was used as the reagent.
