Molecules of Life 4 Critical large Molecules- 1.) Carbohydrates 2.)Lipids 3.)Proteins 4.) Nucleic Acids -On the molecular scale‚ members of three of these classes--- Carbohydrates‚proteins‚ and nucleic acids--- are huge and therefore called Macromolecules. - Architecture of a large biological molecule helps explain how that molecule works. ---------------------------------------------------------------------------------------------------------------------------- Macromolecules

are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and nucleic acid. They are mostly made up of hydrogen‚ carbon‚ oxygen‚ nitrogen‚ sulphur and phosphorus. 1. Carbohydrates Carbohydrates are organic compounds that with the combination of carbon‚ hydrogen and oxygen in a 1:2:1 ratio. Carbohydrates can be separated into three groups‚ monosaccharide‚ disaccharides and polysaccharides. Monosaccharide is the monomer of carbohydrates which contain hydroxyl group‚ such as glucose

Abstract The aim of the experiment is to test the existence of macromolecules which are carbohydrates‚ lipids‚ nucleic acids and proteins in given samples. The first experiment is to test the existence of carbohydrates in starch suspension and potato cell. If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added

Negative Side Effects of a Low-Carb Diet Low-carb diets can be a healthy and efficient weight-loss program‚ but they can be risky‚ as carbohydrates are the only sources of energy for your crucial body organs such as the brain‚ central nervous system and the kidneys. According to the Mayo Clinic‚ low-carb diets increase the levels of blood sugar and make your body use its fat stores. However‚ low-cab diets have some negative side effects associated with them.

To steer clear of freshman weight gain‚ closely monitor your carbohydrate intake. Stay away from meals heavy on processed food and sugary snacks. Instead‚ consume as many fresh vegetables and fruit as you can. Also focus on whole grain foods. Both of these choices will help you feel more energized. A diet with too much

found that when I am very busy I tend to eat less and healthier. When I am just sitting around I tend to eat more than necessary and the foods are not as good for me. Using this tracker has really helped me to see what I am consuming‚ as far as carbohydrates‚ fats‚ sugars‚ proteins‚ sodium‚ and total calories. I have also been able to tell that the more active I am the more calories that I burn in a day. Before I started using the tracker I never gave much thought to how many calories I was burning

are carbohydrates‚ lipids‚ proteins‚ nucleotides‚ and water. These are all very important to humans and without them we would not be able to survive. They have many functions that encourage a human cell and a human body to function. Carbohydrates include sugars and starches‚ contain carbon‚ hydrogen‚ and oxygen which appears in a ratio of 1:2:1. Carbohydrates are classified according to size as monosaccharides‚ disaccharides‚ and polysaccharides. The primary function of carbohydrates is to
