Polymer

a) A polypeptide is a linear polymer of amino acids, linked together by peptide bonds, whereas proteins are functional products of polypeptide bonds and other factors. A native protein is one with all polypeptide bonds formed together in its normal, biological form. A denatured protein…

para. 3) The difference between DNA and RNA is that RNA has the ribose sugar backbone, and has a hydroxyl (-OH) group that DNA does not have. “A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers containing long chains of nucleotides. A nucleotide entails sugar molecules either ribose in RNA or deoxyribose in DNA, attached to a phosphate group and a nitrogen containing base.” (Talking glossary of genetic n.d.) DNA is made out of what is known…

While coaching, I 've had to be organized, punctual, professional, and I 've had to distinguish myself as a role model. I believe labeling myself as a "role model" rather than a "coach" allowed for a relationship with bi-directional respect. Being respected by my players has allowed me to mentor them, not only in the discipline of athletics, but in many important life values. Furthermore, while coaching, I 've had to refurnish my intercommunication skills when talking to people with different…

An insight in the biophysical properties of bio macromolecules Natural biopolymers such as nucleic acids, proteins and carbohydrates are essential for life as we see it today. It is incredible to think how this vast set of molecules that are in every living thing, from bacteria to human beings, are mostly made up by six elements (carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus). These biopolymers have the properties to, from small monomers, build giant tridimensional structures with a…

number 1, degradability, is not the most important criteria, and number 7, cost, is not necessarily the least. Most of the potty used in healthcare nowadays are made of ubiquitous polymers such as Polyethylene and Polypropylene, which are generally non-biodegradable under normal environmental conditions. Thus, degradability is significantly low. For an overnight-or-one-day use product like healthcare potty, such low degradability is…

plastic 4. Plastic in the environment 5. Bioplastic and Biogradable plastics 6. Conclusion 7. Bibliography 1. From food containers to cars and from toys to technology, everything can be made out of plastic. Plastics are carbon based polymers (polymers mean something of many parts) mostly made from petroleum. There are approximately 100 million tons of plastic produced every year. Some people believed that we have entered the age of plastic. The word plastics means flexible so it is…

They are said to be penicillin antifungals as they somehow have a similar mechanism of action against bacteria. Beta glycans are polymers of carbohydrates that can be cross linked with other cell walls of the fungi. Micafungin, anidulafungin and caspofungin are some examples of semisynthetic echinocandins. They are medically used as fungicides for some yeasts, they are used against…

Primordial Soup Hypothesis: The scientist involved in the hypothesis was A.I. Oparin and J.B.S. Haldane. The year the hypothesis was presented was in 1920. The claim of the scientist was that life began in a pond or ocean and chemicals in the atmosphere mixed to form all the the species today. The evidence that was presented to the scientist was that the first organisms were autotrophs. The experiments the scientist did was they mixed methane, ammonia, water , hydrogen , and not oxygen. The…

Dental plaque is a diverse microbial community that forms on the surface of your teeth and is embedded in a matrix of polymers that originates from bacteria and saliva. Plaque develops when foods that contain carbohydrates, such as sugars and starches, are frequently left on your teeth. When you eat or drink foods such as milk, soft drinks, raisins, desserts, or candy…

Recreational Scuba Diving is a popular sport that people have been practicing for decades. While almost completely self-regulated, the sport has an excellent safety record that has only improved with the technological advancement of equipment and safety procedures. Every day people across the planet enjoy traveling under the waves where they see another world with strange, foreign creatures. In a world where we only protect what we value, it helps to have as many people as possible come to…
