This odor has created a stir in the scientific community because what was thought to be a common odor known to everyone turned out to be not so true....

...me of the samples could have had ample amounts of the sulfur molecules while other samples could have had lesser amounts making it either easier or more difficult for the different subject’s to perceive the odor. Much like the experiment conducted by Lison et al. in 1980 this experiment really just proved that at varying concentrations different people can smell the odor. It did not present clear cut data that proved whether there really are “smellers” and “nonsmellers.” Doing an experiment that would use specific amounts of the common sulfurous compounds found in the urine after asparagus ingestion with known dilutions and having volunteers determine whether or not they could smell the specific odor would help to actually prove if there is a distinction between “smellers” and “nonsmellers” or just variations between different individual’s sensitivities to the smell.

- Dietary fibre is widely distributed in plants and consumed as food which are not fully or rapidly digested or absorbed in upper gastrointestinal tract (Schultz, 2011). They are chemically consisting of cellulose, noncellulosic polysaccharides, and lignin. Cellulose is a non-soluble crystalline linear polymer with up to 10,000 of 1-4 β glucose units (Kay, 1982) and it serves as functional fibre when added to food (Gropper, Smith & Groff, 2009). Foods contain high cellulose include bran, nuts, apples, root vegetables and cabbages (Gropper, Smith & Groff, 2009).... [tags: metabolism, cellulose, starch]

- What are organic compounds, you may ask. Well organic compounds are compounds that always contain carbon, or any compound that contains a carbon atom. But some describe organic compounds as any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly are hydrogen, oxygen, and nitrogen. But there are a few exceptions to this organic rule, which are carbon monoxide, carbonates, carbon dioxide, cyanides, cyanates, carbides, and thyocyanates, which are all considered inorganic....

- Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…")....

- Description Think about these substances: mothballs and cinnamon. Both of these have a strong and unique smell. This is because these substances are made of aromatic compounds. In this lesson, we will learn all about aromatic compounds. !!!Aromatic Compounds Let’s think of substances that have are fragrant or have distinct odor like perfume, vanilla and cinnamon. All these substances are known to have a distinct smell and are fragrant, or we can say aromatic. The smell is because these substances are made of aromatic compounds....

- In the experiment “Digestion of Carbohydrates by Salivary Amylase” this dealt with a test where amylase was observed from a saliva sample and starch mix. Salivary amylase is a digestive enzyme that catalyzes the hydrolysis of starch of starch into simpler compounds (Saunders 1). The main function for salivary amylase is to break down starch. When it comes to starches, they are known to be complex carbohydrates. In order to see whether or not the amylase broke down the starch, you can add iodine to the saliva sample and starch mix....

- The beginning process of digestion starts as pizza enters the gastrointestinal tract through the mouth, where the oral cavities begin mechanically breaking down pizza by the cutting, ripping, and grinding actions of the teeth. As the pizza breaks down it is mixed with saliva; salvia contains salivary amylase, this converts the starches in carbohydrates into simple sugars. Therefore, as your saliva and rolling motion of the tongue turns the pizza into a soft, pliable ball called a bolus. As the bolus slides down into your throat (pharynx), this allows for you to swallow.... [tags: Stomach, Digestion, Digestive system]

- The digestion system is also called the gastrointestinal (GI) tract, which is an open tube run from the mouth to the anus. It contains many different organs that have different jobs and function to help break down the food molecules into smaller molecules for our body to ingest and absorption nutrients, vitamins, eliminate toxic substances. The first digestion always takes place at the mouth by using teeth to chew or grand food into smaller molecules which make it easier for the digestion process....

- !!!What Is A Chemical Formula. Everyday, we encounter chemical substances. In our household alone, substances that we use to clean, and those that are staples in our medicine cabinet, as shown in the picture below, are made up of chemical substances. These chemicals that we use everyday are made up of atoms of a fixed proportion and these atoms are arranged in a certain way. How do we know what the atoms are, their proportion as well as their arrangement. This information can be gathered from the chemical formula of the substance....

- Purpose The purpose of this experiment is to use our knowledge from previous experiments to separate a copper compound and from there make calculations relevant to the experiment. The calculations that we had to make in this experiment had to do with finding the percentage of copper in copper compound and from there find the formula weight of the copper compound. Question or Problem The question that was proposed by the instructor for investigation was: Can the % composition of an element in a compound be determined accurately (Lab Manual 61)....
