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

Tok Essay “We see and understand things not as they are but as we are”‚ this claim shows how much our beliefs and experiences changes how we view the world. Our beliefs and experiences are what make us who “we are”‚ therefore this are what influence on our ways of knowing. Since the ways of knowing is what shapes our understanding of the world and views then we can see things as “we are”. Examples of this would be: “The needs of the many outweighs the need of the few”(Star Trek II: The Wrath of

C6H12O6 + 6O2. The conversion of sunlight energy into chemical energy is associated with the green pigment chlorophyll (contained in the chloroplasts of a cell.) This is the compound that traps the sun’s light to start the process of photosynthesis. Glucose molecules are very simple sugars‚ and carbon atoms are locked up in them. The sugars are then converted into other molecules such as starch‚ fats‚ proteins‚ enzymes‚ and DNA. The sugar is

Refined sugar is consumed eating by processed foods such as white bread‚ pasta‚ soft drinks.etc. Sucrose provides our bodies with energy. After this substance is consumed‚ it decomposes into its two fundamental monosaccharides (glucose‚ and fructose). Next‚ the glucose and fructose molecules are quickly absorbed into our bloodstream and energy is obtained. Even though sucrose is used as a source of energy in our bodies‚ too much of it can be harmful. When sucrose is consumed daily in large amounts

The hydrolysis was performed using ACR in a concentration of 5 FPU.g-1. The EH was performed following the standard conditions in sequential and in simultaneous reactions. After the hydrolysis‚ glucose concentration was determined using the glucose oxidase kit (Doles Reagents ®) following the manufacturer’s guidelines. The results were compared by statistical analyses (Student’s t testy-test). Significant differences were obtained when p ≤

Carbohydrate presentation: SCI 241 Sovanna Ath What is Carbohydrate? * Source of energy * Effects of too much carbohydrates A CARBOHYDRATE IS the ideal source where your body get your energy from. Even though carbohydrates are good for your body too much of it can upset the delicate balance of your body’s blood sugar level which can result in fluctuation in energy and mood that leave you feeling irritated and even tired. It is also better for your body to have a balance of carbohydrates

Introduction The objective of this experiment is to identify if the 12 provided solutions contain starch‚ glycogen‚ reducing sugars or proteins. The four major biological macromolecules are carbohydrates‚ lipids‚ proteins and nucleic acids. Abundant elements in the world such as carbon and nitrogen bond in different ways to form many different molecules. The functional groups are what determine their characteristics. During the experiment‚ there will be 3 test. The iodine test is completed to

THE GREAT METABOLIC RACE INTRODUCTION During exercise‚ carbohydrates and lipids are required in order to provide energy for the working body. The inherent reduced nature of these compounds allows for partial or complete oxidation in extracting energy in the form of adenosine triphosphate (ATP). The varying chemical structure of the macromolecules evokes different processes for their complete utilisation. This paper seeks to expound on the mobilisation of these fuels‚ the biochemical pathways that
