Most abundant organic molecule in nature a) 3 major classes: Incarcerations – simple sugar – polyhedron alloyed or ketene; represent individual sugar Electrocardiographs – consist of short chains of macroeconomics units joined together by covalent bonds; 2-10 strings of sugar Polysaccharides – long chains having hundreds or thousands of macroeconomics units b) Functions: Provide energy thru oxidation – glucose oxidized for energy Supply carbon for synthesis of cell components Energy storage to form a part of structural elements of some cells and tissues; loose stored as glycogen c) Classification General formula (CHIC)n where n is any integer from 3-7 Incarcerations are either alludes or stones Alludes – incarcerations that contain alludes Ketosis – incarcerations that contain stones d) Also classified by number of carbons: 3 carbons – triodes, 4 carbons – tresses, 5 Co’s – pentose, 6 Co’s – hoses, 7 Co’s – heptanes Each of these exist in 2 series: lotteries and sidestrokes, lodestars and keystrokes, lodestones and keystones, lodestones and stethoscopes, lodestones and stethoscopes B.

Stereotypical ) Storerooms: all atoms are bonded together with exactly the same bonding pattern but differ only in the arrangements of their atoms in space b) Moisteners: Non-superimposed mirror-image pairs of storerooms (left and right hand) Observed only when a carbon atom has 4 dif groups attached to it (e. G. CHEWY also called choral molecules) One of the necromantic pair is a member of the C)-family and other is L-family c) Properties of Moisteners Have identical physical and chemical properties They rotate the plane of the plane-polarize light by equal degrees but in opposite erection Those that rotate plane-polarize light clockwise are called declaratory and are designated and plus (+). Those that rotate plane-polarize light counterclockwise are called laboratory and are designated by a sign (-). When both moisteners are present the net rotation of plane-polarize light is zero (I. E. Optically inactive) and mixture is retorted to as racemes mixture d) D- Or L- configuration Incarcerations contain choral centers so they can exist as moisteners known as D or L The most oxidized C or most oxidized end is drawn at the top The position of hydroxyl group on the penultimate C; choral C furthest from carbonyl group (oxidized end) determines configuration: If -OH group is on right, the molecule has D- configuration If -OH group is on left, molecule has L-configuration e) Stereotypical: Almost all incarcerations contain choral centers Can rotate plane of polarize light Exist as pair of moisteners Also exist as toastmasters – isomers that are not moisteners. Dosimeters that differ at only a single carbon other than the reference carbon are Ephemeris. E. G. Glucose & calaboose – differ at CA C.

Cyclic structure a) Worth Projection Sugars that contain 4 or more Co’s exist in cyclic forms Sugars that may cycle to 5-member ring (furans) or 6-member ring (paranoia) A new choral center is generated when ring cycle and resulting pairs toastmistress are called monomers. These are designated alpha or beta. In Worth Projection of any cyclic form of a D-sugar the -COACH group is always “up” with the following 2 configurations. When the -OH group at the anorexic carbon is “up” or CICS to -COACH group, sugar is 3-D-sugar (B-monomer) When -OH group at anorexic carbon is “down” or trans to -COACH group, sugar is a-D-sugar (a-monomer) II. Incarcerations A.

Reactions of Incarcerations a) Miniaturization – interconnection between cyclic forms; The collocation RSN is an equilibrium RSN and the various forms interconnect thru central alloyed or ketene form (miniaturization) b) Oxidation-reduction RSN Oxidation: The alloyed group may be oxidized by metal ions such as Cue+ and certain enzymes to yield Aladdin acid Oxidation of COACH but not alloyed yields ironic acid Oxidize both alloyed and hydrometer group Sugars that are oxidized by weak oxidize agents (Benedicts Reagent) are called educing sugars Reduction: Reduction of alloyed or ketene group yields a sugar alcohol or Litton. The Litton cannot cycle and remains as the open chain c) Glycoside Formation Hemispherical and inseminate will react Witt alcohols to tort acetates and kettles. T is a glycoside linkage and the compound is called a glycoside.

If an acetate is form from 2 incarcerations the resulting glycoside is called a disaccharide d) Commiseration Change of configuration at a choral center or an Aledo’s-ketosis conversion e) Sterilization Phosphate and sulfate esters of crab molecules are common. Sterilization changes the sugar’s chemical and physical properties. Often phosphorescently activate a sugar for further RSN B Other Derivatives a) Decoy sugar – replace hydroxyl group with hydrogen L-Focuses (derivative of C)-manses) 2-Decoy-B-C)-ribose b) Amino sugar – replace hydroxyl group with amino group.

Disaccharide A.

Lactose a) Occurs only in milk b) Made up of B-C)-calaboose & either a or b+glucose; linked by -4)glycoside bond c) Is a reducing sugar BC of potentially free carbonyl group in glucose d) Must be hydrolysis by lactate into calaboose & glucose prior to absorption from intestine into bloodstream; without this enzyme – lactose intolerance to milk products. C.
