BIOLOGICALLY IMPORTANT MOLECULES Abstract Compounds containing the element carbon‚ called organic compounds‚ are the most important substances that make up living organisms. There are thousands and thousands of different organic compounds. To identify the major types of organic compounds in living organisms ‚ several biochemical test were used . Introduction Organic molecules are those primarily made up of carbon‚ hydrogen and oxygen. The common organic compounds of living organisms are

saliva is added before it is swallowed. This is where the first enzymes start work. There are two enzymes found in the saliva of the mouth‚ salivary amylase and lingual lipase. Amylase breaks down dietary carbohydrates such as monosaccharides‚ disaccharide sugars and complex polysaccharides (starch). Monosaccharide’s can be easily absorbed into the bloodstream so the others need to be broken down into these before they can be absorbed (Derrickson‚ Tortora 2006 p906). The salivary amylase starts

Please use the book‚ PPT lecture handouts‚ and internet to answer the following six questions: Question 1 (8 points) Mr. Tony‚ a biology teacher‚ gives his student Ziad four samples and tells him they are lysine (an amino acid)‚ lactose (a disaccharide)‚ insulin (a protein hormone)‚ and RNA. The samples are in test tubes marked 1‚ 2‚ 3‚ and 4‚ but Ziad is not told which compound is in which tube. He is asked to identify the contents of each tube. a. In his first test‚ Ziad tries to hydrolyze

glucose‚ starch‚ truvia‚ sucralose‚ saccharin‚ fructose‚ maltose‚ sucrose and lactose‚ there will be different fermentation rates because sugars like fructose have a 5-ring structure differing greatly from glucose. Lactose won’t ferment because this disaccharide is very complicated for enzymes to break down into. When using the pipet stopper‚ CO2 releases itself after pushing itself out of the tube as an air bubble. A paperclip in the bottom of a flask while being stirred with the yeast and sugars helps

The medical community characterizes Irritable Bowel Syndrome (IBS) as a gastrointestinal condition involving intestinal motility dysfunction. This condition affects 12-14% of the adult population in the United States‚ appearing almost 50% more in women than in men (Anastasi‚ 2013; Smeltzer‚ Bare‚ Hinkle‚ & Cheever‚ 2010). According to Anastasi (2013)‚ health care practitioners can diagnose IBS six months after appearance of symptoms with the use of the Rome III Diagnostic Criteria. The Rome III criteria

Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids‚ carbohydrates‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain
