| lactose |
1. β-D-galatose + β-D-glucose→joined by a β(1-4) glycosidic linkage 2. principal carb in milk (milk sugar) 3. lactose intolerance = no enzyme to hydrolyse to galactose & glucose |
| Define Aldose | Aldehyde functional group |
| Aldose | a carb contains a aldehyde |
| chitin | An important structural polysaccharide that insects use to make exoskeletons. Can also make cell walls for fungi. |
| polysaccharides are important in storing | energy |
| Define Disaccharide | Compound of 2 monosaccharides |
| Galactose | componenet of the disacharide lactose ( milk sugar) , also a blood component. |
| Glycosidic Bond | bound together by "O" atoms. |
| aldoses | a monosaccharide that contains an aldehyde functional group |
| Ketose | any monosaccharide sugar that contains a ketone group. ex. fructose |
| hydrolysis means | to break apart with water |
| Which Carbohydrates are used for stored energy? | Polysaccharides |
| helium | colorless liquid helium existing below its boiling point of 4.2 K and above the lambda point of 2.186 K. |
| Glucagon | stimulates the release of glucose into the blood |
| biochemistry | study of the chemical substances found in living organisms and the chemical interactions of these substances. |
| polysaccharide |
1. many mono bonded by glycosidic (acid) linkages 2. not sweet, negative w/Tollens & Benedicts b/c so many mono the concentration of aldehydes are low 3. limited water solubility 4. ex. cellulose, starch in plants, glycogen in animals, chitin in arthropods |
| microfibrils | Main architectural unit of the plant cell wall composed of parallel cellulose molecules. |
| sphingolipidoses | result from defects in catabolism of sphingolipids |
| Define Lipolysis | Conversion of carbohydrates to fatty acids |
| Haworth Projection | cyclic form with atoms in spatial arrangements |
| storage polysaccharide: starch |
1. glucose is monomeric unit 2. storage polysaccharide in plants 3. 2 types a. amylose b. amylopectin |
| Ruff Degradation is used for... | removes C1 from aldose |
| glycogen | A polymer made up entirely of glucose molecules that is used for storage in animals. More complex than starch. THE storage polysaccharide in animals. |
| Which of the following is not a disaccharide?starchmaltosesucroselactose | starch |
| Define Monosaccharide | simple sugar = can't be further hydrolized |
| element | one of a class of substances that cannot be separated into simpler substances by chemical means, part of the periodic table |
| properties of enantiomers |
have same properties except for 2 areas: 1. their interaction w/plane polarized light -a pair of enantiomers will rotate light to the same extent but in opposite directions 2. their interaction with other chiral substances - a pair will react differently w/other chiral molecules (ex. left & right handed baseball gloves) - solubility will be different - will have the same BP, MP & density - our bodies react differently. one may react higher & one might be inactive |
| A formula which shows how the atoms are bonded in a molecule is called themolecular formulastructural formulaelectronic configurationorganic formula | structural formula |
| Diagnosis of Diabetes | Testing is performed based on high risk criteria |
| oxidation to acidic sugars | -can yield 3 different types depending on oxidizing agent |
| In cyclic sugar, ____ means anomeric hydroxyl group trans with last carbon, while ____ means anomeric hydroxyl group cis with last carbon. | alpha (axial), beta (equatorial) |
| Simple Carbohydrates: sugars, including both single sugar units and linked pairs of sugar units (1 answer) | the basic sugar is a molecule consisting of six carbon atoms together with oxygen and hydrogen |
| amino sugar formation |
1. one of the hydroxyl groups of a mono is replaced with an amino group 2. important building blocks of polysaccharide such as chitin |
| When making bonds | when bonded it is no longer a reducing substance |
| Types of Diabetes Mellitus |
Type 1 - Insulin Dependent Type 2 - Non-Insulin Dependent Gestational - During pregnancy |
| What is the purpose of the Wohl Degradation? | reverse of Killiani Fischer after making oxime intermediate (removes stereochemistry at C2 of original aldose) |
