Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes sulfur. Proteins are covalently bonded

Arturo Contreras T. Conner-Moore Chemistry I Honors 22 August‚ 2016 Why is a Soccer ball consider Chemistry? What is chemistry? The word “chemistry” dates back to 1590-1600‚ but it is debatable that either the Egyptians or Greeks were the first to introduce chemistry to the world. What society does know‚ it is that Antoine Lavoisier is known as the “Father of Chemistry.” Lavoisier was the first to document how he compiled and completed the first list of elements. He discovered and named the elements:

compounds; 20% of the content of a plastic is composed of additives. Biodegradable plastics are usually derived from proteins such as those that are present in a potato plant. Polymers are large molecules consisting of many repeating units‚ called monomers. Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics

Biochemistry: categories of organic compounds Ruddy Severino There are four major compounds that compose the human body. It is impossible that anything living on earth today can live out these organic compounds. Those compounds are carbohydrates‚ lipids‚ proteins‚ and nucleotides. Each compound has a major important function that is essential to the human body as well as other living organisms on earth. Carbohydrates serve as the main source of energy. Carbohydrates contain carbon‚ hydrogen

about the nature of this evolution are still debated‚ but the general idea can be explained in a four-stage hypothesis. In this four-stage hypothesis‚ the first stage was the abiotic formation of organic molecules‚ such as amino acids and nucleotide monomers. The idea that organic molecules can be formed abiotically was based on the fact that the early Earth was abundant with elements necessary to create the modern biological macromolecules. In fact‚ the famous experiment performed by Harold Urey and

“New indoor shooting range ready to open” Summary This article is mainly about a local shooting range that just opened and is ready for shooters. Stephen Stewart’s C.I. Shooting Sports‚ 700 Wylie Drive‚ in the Crossroads Center‚ has 16 shooting lanes – all rifle-rated‚ he said. He also comments‚ “You’re looking at the best range equipment made.” The bullets are slowed and stopped by chunky rubber at the other end of the shooting range. Stewart describes it as “shooting into a bed of rice

Synthesizing Polymers “Making Silly Putty” In college‚ there are many things students take for granted. One thing we all take for granted the most is keeping a fresh perspective on the curriculum we are taking. This is an especially hard task when it comes to the more challenging subjects like science and mathematics. Chemistry‚ in particular is one of the most challenging subjects for any student‚ and many factors contribute to the students’ understanding of the course. Things like the right professor
