Glucose store in liver and muscles in form of glycogen and provides the energy of human beings. Fructose Fructose has molecular formula of C6H12O6. Fructose has same molecular formula as the molecular formula of Glucose but different structure. The structure of fructose differs from glucose at carbon 1 and 2 positions due to change of carbonyl group. Fructose is sweet sugar occur in nature.
C) Hydrogen bonds can form between neighboring molecules. D) Hydrogen bonds are important forces for tertiary structure of proteins. E) Hydrogen bonds are responsible for many of the unique properties of water. Answer: A Diff: 6 Page Ref: 31 14) ________ are molecules that contain primarily carbons and hydrogens linked together by nonpolar covalent bonds. A) Lipids B) Carbohydrates C) Proteins D) Nucleotides E) Polysaccharides Answer: A Diff: 4 Page Ref: 21 4 Copyright © 2011 Pearson Education, Inc. 15) ________ are molecules composed of a glycerol and three fatty acids.
Animals can synthesize carbohydrates from amino acids, but most are derived ultimately from plants. Glucose is the most important carbohydrate; most dietary carbohydrate is absorbed into the bloodstream as glucose formed by hydrolysis of dietary starch and disaccharides, and
The higher members of the aliphatic carboxylic acids, from C12-C18 are known as fatty acids that are found in nature as natural fats or esters of glycerol. Moreover, this group is the starting material for many essential organic compounds like esters, acid chlorides, anhydrides, amides
STRUCTURE OF GLUCOSE Introduction to glucose: There are many types of carbohydrates but the most important one carbohydrate in human body is glucose (C6H12O6). Glucose is also termed as monosaccharide due to the fact that it forms one simple building block of more complicated carbohydrates like starch, glycogen, maltose, sucrose, lactose etc. It is also known as dextrose due to its occurrence in optically active dextro-rotatory isomers . The name "glucose" derived from the Greek word which means "sweet wine, must". The suffix "-ose" indicate that a glucose is a carbohydrate .
It usually takes place in the leaf and it is used by plants to create sugar from sunlight. Eukaryotic cells within the plant are able to do this type of process by capturing light energy from the sunlight through the use of pigments and converting it into chemical energy. Without the sunlight this process and its stages wouldn’t be able to function properly to create sugar due to it being a light-dependent reaction. Photosynthesis has to take place due to the fact that it helps eukaryotes survive. During this cellular process, oxygen is released in the form of waste in to the atmosphere which is what organisms have to breathe in order to
2nd step: The second step consist of the start point of glycogenesis and it’s a reversible reaction which transform the Glucose -6P to Glucose -1P. The enzymes responsible from this reaction is the Phosphoglucomutase. Glucose -6P Glucose -1P The phosphoglucomutase catalyze the reaction by moving a functional group, here it’s a phosphate group. 3rd step: The third step consist to transform the Glucose -1P to UDP-Glucose. The enzyme responsible is UDP-Glucose pyrophosphorylase and this reaction consumes UTP.
Chemical Reaction of Carboxylic Acids Main Contributor: Chen Swee Lun Carboxylic acids consists of a huge and diverse group of organic compounds that contain the carboxyl group (-COOH). The general formulae for carboxylic acid is CnH2n+1COOH. The presence of hydrogen atom in the carboxyl group gives carboxylic acids an acidic property when the acid is dissolved in water. Methanoic acid, ethanoic acid and propanoic acid are some examples of carboxylic acids. Formic acid, acetic acid and propionic acid are the common names for the three examples respectively.
The oxidation of these molecules is primarily used to transform the energy contained in these molecules into ATP. ATP os a large source of energy for muscle contractions and can therefore be referred to as "energy currency" of the cells. The fuel molecules is first converted into acetyl-CoA and then can be inserted in the Krebs Cycle. Looking at the path of a nutrient, such as glucose, the oxidation of the molecule takes place in the glycolysis. The product of the glycolysis is pyruvate.
