somebody did a lab for testing macromolecules, based on your knowledge about how different macromolecules react tell me if these rests are reliable or not and state reasoning, Benedict's reagent: Pour 300ml of water into a 400ml beaker. Secure the beaker in a ring clamp and place the beaker on a hot plate. Suspend the thermometer in the water and heat the water to approximately 80 degrees celsius. Using a graduated cylinder measure 3 ml of each of the following: distilled water, baking soda, glucose, milk, sardine, instant potato, table sugar, and unknown product pour each solution into a clean test tube and label the test tubes with marker. After add 1 ml of benedicts reagent to each test tube then transfer the test tubes to the hot water bath and observe six minutes.\ Results: Distilled water:blue Baking soda: light blue Glucose: yellow Milk: yellow Sardine: blue seperated Instant potato: white Table sigar: light blue Unknown product: dark blue Iodine (logols solution) Using a medicine dropper, place a drop of distilled water, baking soda,starch, milk, sardine, instant potato, table sugar, and unknown product . with a drop of lugols solution on a depression spot plate and record results. Results: Distilled water: brown yellow Baking soda: brown yellow Starch: blue black Milk: brown/ not well mixed Sardine: yellow brown not mixed Instant potato: blue black Table sigar: brown yellow Unknown product: blue black Sudan iv: Measure 3ml iof the following: distilled water, baking soda, lipid(oil)(IN water) milk, sardine, instant potato, table sugar, and unknown product . pour each solution into a clean labled test tube add 6 drops of sudan iv to each test tube and shake with thumbs fopr 2 minutes then record results. Results: Distilled water: dark red Baking soda: light red Oil in water: orange Milk: light pink Sardine: pink orange Instant potato: orange pink Table sigar: dark pink orange Unknown product: light pink with foam Brown paper bag: Draw a circle on a piece of brown paper for each sample which are: distilled water, baking soda, lipid(oil)(IN water) milk, sardine, instant potato, table sugar, and unknown product .when they dry hold the sample up in the light and record whether translucent or not. Results: Distilled water: not transluecen Baking soda: slightly Oil in water: yes Milk: slight Sardine: very Instant potato: no Table sigar: no Unknown product: slightly Buritet regent: Measure 2 ml of the following: distilled water, baking soda, protein(albumium), milk, sardine, instant potato, table sugar, and unknown product . then add 2ml of buritet reagent to eacyh test tube and tap the test tube with your finger to mix the contents and record results. Results: Distilled water: blue Baking soda: blue Albumium: violet Milk: milky purple Sardine: dark purple Instant potato: light blue Table sigar: blue Unknown product: dark blue
