Introduction The objective of this experiment is to identify if the 12 provided solutions contain starch‚ glycogen‚ reducing sugars or proteins. The four major biological macromolecules are carbohydrates‚ lipids‚ proteins and nucleic acids. Abundant elements in the world such as carbon and nitrogen bond in different ways to form many different molecules. The functional groups are what determine their characteristics. During the experiment‚ there will be 3 test. The iodine test is completed to

To begin the appropriate weight of agarose is weighed out and added to a specific concentration of buffer‚ this mixture is then heated to ensure that all of the agarose polysaccharide is dissolved into the buffer. Once the agarose and buffer are completely mixed they are cooled to room temperature. Dyes such as ethidium bromide can then be added in order for the bands created when the current is applied to be visualized.

Cell wall composition • :Gram negative . • Gram positive. b. Nutritional requirements : • Autotroghs:take nutrition from carbon dioxide. • Heterotrophs take the nutrition from organic carbon(carbs‚lipids‚protein) • Prototroph: take nutrition from sunlight. • Chemotrophic take nutrition from chemicals. c.

Unit 7 Assignment 1: Nutrition Kara Graves Breckinridge School of Nursing GE 150 Katy Lunger August 7th‚ 2014 Proteins are made up of groups of twenty different amino acids. In the average adult‚ twelve of those acids are made in the body‚ and the other eight we have to ingest through our food. Those eight are called the essential amino acids. Amino acids cannot be stored in the body‚ so we need to eat foods regularly that contain the essential amino acids. We get most of our high quality

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that

Dextrinization is a process in which starch is converted into dextrins. Dextrin’s are any various polysaccharide which has been collected by the starch. This is made possible by the application of heat or acids. Dextrinization is mainly used as a thickening agent or a rising tool. Dextrinization occurs in Step 5 “bake for 15mins or until golden brown” this

anaerobe‚ lastly‚ it is a Prokaryote. Furthermore‚ Proteus mirabilis is characterized by its swarming motility‚ its ability to ferment maltose‚ and its inability to ferment lactose. P. mirabilis has the ability to elongate itself and secrete a polysaccharide when in contact with solid surfaces‚ making it extremely motile on items such as medical equipment (catheters). Moreover‚ Proteus mirabilis is part of the normal flora of the human gastrointestinal tract. It can also be found free living in water
