Sugar taps into a powerful human preference for sweet taste‚ says Marcia Pelchat‚ PhD‚ a scientist at the Monell Chemical Senses Center‚ a basic research institute in Philadelphia. “We’re born to like sugar‚” she says. Sugar is sucrose‚ a molecule composed of 12 atoms of carbon‚ 22 atoms of hydrogen‚ and 11 atoms of oxygen. Like all compounds made from these three elements‚ sugar is a carbohydrate. It’s found naturally in most plants‚ but especially in sugarcane and sugar beets. The

Diffusion and Osmosis Experiment Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled

Modernization from Consumption of Sugar According to Wikipedia‚ “modernity” is defined as a post-traditional period that is marked by the move from feudalism towards capitalism and industrialism. From the sixteenth century through the nineteenth century‚ many countries and economies progressed towards a more modern environment. Many factors contributed to the push for modernity; however‚ the sugar industry exhibited major influence throughout the world. Once sugar cane was established in the Caribbean

He had risked his life‚ both by going there without permission‚ and by taking the potato. But it’s so very important to him‚ so he did it anyway. And now‚ here he is‚ waiting impatiently to go into his barracks. Finally‚ the endless roll call is over‚ and he sighs with

Diffusion is the molecular net movement from a higher concentration to a lower concentration. For instance‚ when a person is smoking‚ the smoke diffuses into the air. The molecules in the smoke‚ released from the cigarette‚ travel through the air. Here is how it occurs. When molecules are close enough‚ they collide with each other‚ their kinetic energy changes. Due to the direct relationship between diffusion and molecular kinetic energy‚ the molecules move away from the point of the collision as

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no

OSMOSIS ASSESSMENT TASK Introduction Osmosis is the net movement of water particles from an area where they are in high concentration to an area of low concentration‚ down a concentration gradient. Hypothesis: Will a high concentration of salt solution affect the mass of a potato chip? Variables Controlled variables: -The sizes of the potato chips. Bigger size of potato chips will weigh heavier and the smaller potato chips will weigh lighter‚ if we don’t use the same size of potato chips

was made on whether or not the sugars‚ fructose and ribose would be fermented in yeast (Saccharomyces cerevisiae). By looking at the chemical structures of these sugars given in (Figure 1)‚ we looked for anything that might determine the metabolization of these sugars. An equal 6mL (milliliter) sample of 2.5% fructose and yeast suspension was pipetted into a fermentation tube. The same procedure above was performed with the sugar ribose which has a concentration of 2.5% as well. Once this was

Sugar Studying sugar may seem like an ineffective way to approach the Caribbean’s rise to a globalized economy. It is quite the contrary‚ sugar rose to be an extremely popular and profitable staple for the international food economy. It grew to play a major role in what we know of today as the global food market. Sugar started developing immense popularity around the 1960’s due to colonial slavery‚ the industrialization of a global economy‚ and an increase in tea consumption. Sugar was introduced
