carbohydrates
Carbohydrates are present in sugars, starch, acids, and in many other nutrients that consist elements of carbon, hydrogen, and oxygen. Having a ratio of 1: 2: 1 or written as CH20. A monosaccharide meaning monomer of sugar is a "simple" carbohydrate. Containing backbone of five carbon atoms that are present in ribose and deoxyribose, components of RNA and DNA. Glucose a six carbon atom that is common cellulose, starch, and glycogen are classified as polysaccharide, Known as a "complex" carbohydrate, with straight or branched chains of many sugar monomers. These categories of carbohydrates are tested in two laboratory experiments. It will allow us (my partner and I) to detect the presence of sugar or starch. The first test, using two different solutions to expose the presence of sugar or starch by color alteration. I hypothesize that both samples of the experiment will result differently in order to pursue the next test. The second test consists of 9 food items, identifying the appearance of sugar or starch. I guess in identifying 75% out of the 9 items right. Conducting both experiments will test my hypotheses either right or wrong.The first experiment on °simple± and °complex± carbohydrates, several tools and liqui
We both had amazing outputs; I resulted on having 6 items accurately correct out of the 9. Baking soda solution and vinegar failed both the benedict and lugol¯s iodine fluids, appearing negative results for sugar and starch. I predicted that Salt water would show starch therefore it appeared negative. Vinegar has an acidic elements, that are naturally fermented by which bacterium (prokaryotic) go through, an anaerobic cycle. Baking soda is a sodium bicarbonate, it is naturally occurring in the form of an ore called torna. It releases more OH , which it has a pH above 7. Salt is a sodium chloride, also with a pH number greater than 7. For these reasons, my estimation was not accurate. Some of the items were organic fluids, processed powders, and flavored water, which contain either starches or/and sugars. The categories of carbohydrates were tested in two laboratory experiments. It allowed my partner and I to detect the presence of sugar and starch with indicators, (benedict¯s reagent and lugol¯s iodine). The test results indicated that certain Items were composed of carbon, containing substances that include lipids, proteins, and nucleic acids. Other items were composed of non- carbon such as water, calcium, sodium, magnesium, and other elements. For
