using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for the Grease Spot Test was to test if the substance had a lipid. A positive reaction would make a translucent grease mark on a brown paper bag. The objective for the Dye test was to test for lipids. When mixed with water and the tested substance‚ a positive result will occur in it being separated from the water. The objective of the Protein Test was to test for proteins present

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a

Testing for Sugars‚ Lipids‚ Proteins‚ and Starches in Various Samples Introduction The purpose of this experiment is to define and classify macronutrients identify macronutrients in solutions of unknown composition‚ perform chemical testing methods on foods to test for the presence of macronutrients‚ and recognize experimental controls. Nutrients are divided into two categories‚ micronutrients and macronutrients. Micronutrients are required in small quantities and include vitamins and trace

The most common organic molecules are carbohydrates‚ lipids‚ and proteins. Carbohydrates contain carbon‚ hydrogen and oxygen with a ratio of 1:2:1‚ this means that for every 2 hydrogen atoms there is one carbon atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides

emphasized the use of photosynthetic organisms from aquatic environments‚ especially species that grow in environments unsuitable for crop production. Early in the project‚ macro algae‚ microalgae‚ and emergent were investigated for their ability to make lipids (as a feedstock for liquid fuel or chemical production) or carbohydrates (for fermentation into ethanol or anaerobic digestion for methane production). Macro algae (seaweeds) are fast-growing marine or freshwater plants that can reach considerable

and are found in the forms of starch‚ sugar and fibre. Additionally‚ carbohydrates move into the small intestine‚ where enzymes released by the pancreas break those carbohydrates into simple forms‚ so they can be absorbed into the bloodstream. • Lipids that are consumed‚ are mainly fats.

and the causative agent of botulism. Their exceptional toxicity is caused by the highly efficient inhibition of neurotransmitter release at the neuromuscular junction. High affinity binding of BoNTs is mediated by the simultaneous interaction with lipid embedded synaptic vesicle proteins and gangliosides the presynaptic membrane according to the well-established dual-receptor binding model. One peculiarity that is especially pronounced in BoNT serotypes B‚ DC‚ and G – which all use synaptotagmin as

Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

Homeostasis by definition is the technical term for the process of maintaining a constant internal environment despite changes in the external environment. The internal environment comprises of blood‚ tissue fluid‚ body cell contents and all metabolic processes taking place inside the body. This process is essential to the survival of a person and to our species as a whole. The liver‚ the kidneys‚ and the brain (hypothalamus‚ the autonomic nervous system and the endocrine system) help maintain
