TITLE: The Amount of Protein in Chicken Tissues over Cooked Various Periods of Time. ABSTRACT: In this lab‚ we are using a BioRad protein assay dye to determine the concentration of protein in our chicken. The dye binds to the amino acid residues‚ which allow us to find the concentration of protein (BioRad Protein Assay for Tissues). Our hypothesis was the longer chicken is cooked the less protein is available. To test our hypothesis‚ we made samples using our chicken and distilled water to determine

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 The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers.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 can hydrolyze plant starch‚ making glucose available as a nutrient for cells. Cellulose

molecular level – Tutoring for biology Saturated fat vs. unsaturated fat Saturated fat has a lot of single carbon bonds. This makes them much straighter in shape and therefore easier to stack together. It’s called “saturated” fat because the molecule has the maximum amount of hydrogen atoms attached to it as possible. Unsaturated fat has double carbon bonds. Each double carbon bond means two less hydrogen atoms on the molecule. Unsaturated fat also is kinked at each double bond‚ disrupting the

No Sugar shows us a range of responses adopted by Aboriginal people toward white authority. Discuss. The play No Sugar by Jack Davis which is set in the 1930’s‚ explores and evaluates the way Aborigines were treated unjustly and how they responded to this treatment. Jack Davis presents to us the Milimurra family who are essentially the main characters in the play. They are the minority group fighting against the discriminations laid upon on them by white authorities. Without a doubt‚ Davis positions

Discovered in 1838‚ proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential for their functioning. In other words proteins are the building blocks of life. They do many tasks for the human body and other organisms‚ that could not be done individually. These macromolecules could function as structural proteins and form structures such as keratin in hair‚ teeth‚ bones‚ muscles‚ collagen in connective tissues‚ horns in animals

In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol

Starch is a type of Carbohydrate that’s made from thousands of glucose units. Simple sugars are the basic units that make up starch. Carbohydrates provide us with energy so that we can carry out our daily routines. Our body then digests it into glucose so we can have energy to do that. Saliva is a form of chemical digestion that is in the mouth. Amylase is an enzyme that catalysts the breakdown of starch into sugars. Amylase is present in human saliva‚ where it begins the chemical process of digestion

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide sugars of varying chain
