Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that

Carbohydrates‚ Proteins‚ lipids‚ and nucleic Acid Lab Exercise 6 Date: 9/17/12 Bio 102-11 Purpose the purpose of this experiment was to perform test to detect the presence of carbohydrates‚ proteins‚ lipids‚ and nucleic acids. Explain the importance of a positive and a negative control in biochemical test. Use biochemical test to identify an unknown compound. Background Most organic compounds in living organisms are carbohydrates‚ proteins‚ lipids‚ and nucleic acids they are called macromolecules

L.O. 1.1 and 1.2 Carbohydrates are sugars and they are the primary source of energy for our vital functions such as breathing and sleeping. There are two types of carbohydrates‚ simple and complicated. Monosaccharides‚ disaccharides and polysaccharides. L. O. 1.2 Carbohydrates are split into different classifications depending on how many molecules they have. Monosaccharide: one sugar

The intake of the products high in carbohydrates causes the insulin levels to spike. The high amount of insulin locks the fat which leads to the burning of the glucose instead of the fat. A person loses the most weight during the initial period of the low-carb diets. The reason for this is because the low levels of the insulin in the body causes the kidneys to shed an excessive amount of sodium. Moreover‚ the carbs in the bodies are stored in the form of glycogen. The glycogen binds water molecules

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays

BIURET FOOD TEST FOR PROTEINS molecules consisting of one or more chains of amino acids.Proteins are complex molecules that react differently to many compounds but are also fragile and cannot withstand high temperatures or strong acids and bases without degrading. The Biuret Method‚ or biuret test‚ is used to detect the presence of peptide bonds. It has this name because it reacts positively to the biuret molecule’s peptide bonds. Correctly evaluating the number of peptide bonds is a step towards

Lipids Biochemistry November 13‚ 2013 Lipids Lipids are families of biomolecules including fats and oils‚ waxes‚ steroids ‚ cholesterol and fat soluble vitamins. All lipids are naturally occurring compounds varying greatly in structure but share the common feature of being soluble in non polar solvents such as chloroform and ether but not in water. Lipids consist mainly of carbon and hydrogen atoms linked by non polar covalent

Another word for "fats." Lipids can be more formally defined as substances such as a fat‚ oil or wax that dissolves in alcohol but not in water. Lipids contain carbon‚ hydrogen and oxygen but have far less oxygen proportionally than carbohydrates. They are found in places as diverse as egg yolks and the human nervous system and are important component of plant‚ animal and microbial membranes A fatty or waxy are organic compound that is readily soluble in nonpolar solvent (e.g. ether)
