Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

Sugars Starches may be named monosaccharides‚ disaccharides‚ or polysaccharides relying upon the quantity of monomer (sugar) units they contain. They constitute a substantial piece of nourishments‚ for example‚ rice‚ noodles‚ bread‚ and other grain-based items. Monosaccharides‚ disaccharides‚ and polysaccharides contain one‚ two‚ and three or more sugar units‚ separately. Polysaccharides are frequently alluded to as mind boggling starches in light of the fact that they are

two different types of starches used are amylose and amylopectin. To test for the presence of starch‚ the Starch Test is used. This is a simple test in which iodine is added to a given solution. If a polysaccharide such as starch is present then the iodine ion will lodge itself in the polysaccharide chain and give it a black-blue color. If iodine added to a solution turns black-blue than starch is present. If the solution remains the color of iodine‚ reddish-orange‚ there is no starch present‚ a

It can range anywhere for 20 to 80 micrometers thick. Gram-positive cell walls also contains tightly bound polysaccharides‚ such as teichoic acid. Teichoic acid is a polymer of ribitol or glycerol and phosphate. Lipoteichoic acid may also be present in gram-positive cell walls as this molecules binds to lipids in the cell membrane instead of proteins. The molecules

2.1 Sanitation Methods There are Four Methods that conducted on the laboratories in order to detect the presence of microorganisms. There are Rodac Method‚ Swab Method‚ Rinse Method‚ and lastly Open Dish Method and it will be discussed in detail below. 2.1.1 Rodac Method The purpose of this Standard Operating Procedure is to describe a program that will adequately measure the efficacy of disinfection of Rooms and equipment in each laboratory‚ RODAC plates can detect the presence or absence of

Carbohydrates (monosaccharides & polysaccharides)‚ lipids‚ proteins‚ & nucleic acids. 4) What is the original colour of iodine‚ and what colour does it turn in presence of starch and glycogen? Starch: yellow --> blue-black (amylase in starch reacts with iodine) Glycogen: yellow --> reddish-brown (due to the multi-branched component) 5) How do plants and animals store simple sugar glucose? In the form of polysaccharides. In plants‚ starch is the polysaccharide with glucose units linked by

Malaysia is one of the countries with the most abundant types of tropical tree species available in nature. Woods and timber are important in the economic development of Malaysia especially in the import and export industry. One type of woods with such vital function is Leucaena leucocephala. It is a plant species with many branches and numerous clusters of flat pods that enveloped the seeds (Shelton et al.‚ 1994). L. leucocephala was first brought into Southeast Asia in the last few centuries by
