H 2 O Vitamins And Minerals
1,751 wordsWhat exactly do we mean by sugar? Most people would answer by describing the white granulated sugar found on the meal table. That is however only part of the answer. Table sugar is sucrose and is only one of a number of different sugars all of which belong to the carbohydrate group of basic energy foods. Sugars are a major form of carbohydrate and are found in probably all green plants. They occur in significant amounts in most fruits and vegetables. There are three main simple sugars - sucrose,...

Three And Four Reaction Rate
859 wordsTitle: Examining Some Properties of the Enzyme -amylase In this experiment a deeper meaning in the catalysts of reactions is studied. Catalysts accelerate chemical reactions without permanently changing the reaction. Enzymes, catalysts in biochemical reactions, are globular proteins which lower the activation energy needed to begin a reaction and therefore increase the rate at which efficient reactions can occur. Proteins (henceforth enzymes) are complex molecules made of amino acids in polypept...

Ground Level Ozone Carbon Dioxide
2,167 wordsAlternative Fuel Vehicles You Can Buy Today From the earliest days of the automotive industry alternative fuels have always competed with petroleum for powering vehicles. Nicholas Cugnot made the first self-powered road vehicle in 1769 with a steam engine, and the first gasoline automobile didn't appear until over 100 years later from Karl Benz. Through the late 19 th and early 20 th century steam and electric power remained strong contenders. The invention of the self-starter for gasoline engin...

Sugar Molecules Linked Aldehyde Or Ketone Group Monosaccharides
387 wordsThere are three principal kinds of carbohydrates and each are classified according to the number of sugar molecules they contain. Monosaccharides, such as ribose, glucose, and fructose, contain only one sugar molecule. Disaccharides consist of two sugar molecules linked covalently. Familiar examples are sucrose (table sugar), maltose (malt sugar), and lactose (milk sugar). Polysaccharides, such as cellulose and starch, contain many sugar molecules linked together. Monosaccharides are organic com...

Fatty Acids Important Part
603 wordsCarbohydrates and lipids / fats are a very important part of our lives. They have many similarities and differences among each other, which distinguish them from other macromolecules. Carbohydrates, which include sugar and their polymers, are used by organisms for fuel and building material. They come in many various forms going from simplicity to complexity. The simplest, monosaccharides, compose of single sugars whose parts are arranged around asymmetric carbons. They generally have a molecula...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...

Peptide Bonds Test Tube
606 wordsThis lab used many test to determine which functional groups were present in certain substance. The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reduce the Caprice ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when at low levels. In both the onion juice and glucose solution the reducing sugar levels were very high, because the test came back dark oran...

Rate Of Reaction Amount Of Water
1,531 wordsPhotosynthesis is a very important process in nature. It is the production of energy in the form of glucose involving water from the soil, carbon dioxide from the air and light energy. It takes place in all green plants, which use the green chlorophyll, held in chloroplasts in the leaves, to trap light. The main site of photosynthesis is the palisade mesophyll cells in the leaf of a plant. It is these cells that contain the green chloroplasts and are very well adapted to their task. They are nea...
