Cards in this deck (62)
- 1What is biomoleculesBiomolecules are lifeless molecule that are derived in such a way that it produce life
- 2Example of Biomolecules1. carbohydrate
2.proteins
3.enzyme
4.nuclei acid - 3What is other name for carbohydratessaccharides(Sugar)
- 4so what are carbohydrates?Carbohydrates are defined as optically active(Chiral carbon) poly hydroxy aldehyde or poly hydroxy ketone
- 5What are aldehydeCHO group
The carbonyl group is always at the end of the carbon chain.
Example: Formaldehyde (HCHO), Acetaldehyde (CH₃CHO) - 6what are ketonesCO group
The carbonyl group is located inside the carbon chain (not at the end).
Example: Acetone (CH₃COCH₃) (used in nail polish remover) - 7Structural formula of glucoseC6 H12 O6
- 8Fischer projection of glucose
- 9Classifications of CarbohydratesMonosaccharide
Oligosaccharide
Polysaccharide - 10What are MonosaccharideMonosaccharide are most basic form of carbohydrates which cannot be hydrolyzed further
ex- glucose, fructose, ribose - 11Polysaccharide1. A polysaccharide is a polymer of monosaccharides
2. A carbohydrate that, on hydrolysis, gives many units of monosaccharides.
Example: Starch, cellulose, and glycogen - 12OligosaccharideA carbohydrate that
on hydrolysis produces
2 to 10 Monosaccharide
are called as
oligosaccharide - 13Oligosaccharide further divided intoDisaccharides
Trisaccharides
Tetrasaccharides - 14Disaccharides(Yield two monosaccharide units on
hydrolysis)
Examples:
Sucrose : (One glucose unit + one fructose
unit)
Maltose : (two glucose units)
Lactose : (one glucose unit + one galac-
tose unit) - 15Trisaccharides(Yield three
monosaccharide units on
hydrolysis)
Example : Raffinose :
(one unit each of glucose,
fructose and galactose) - 16Tetrasaccharides(Yield four monosaccharide
units on hydrolysis)
Examples : Stachyose : (one
glucose unit + one fructose
unit + two galactose units) - 17Nomenclature of monosaccharide are based on1.Based on no. of carbon
2.Based on functional group - 18How to Know Nomenclature based on no. of carbon are3c: triose
4c: tetrode
5c: pentose
6c: hexose
7c: heptose - 19How to know Based on functional group

- 27Explain and Provide reaction to justify that glucose has 6 carbon
- 28Action of HCN and Hydroxylamine in glucose
- 29What reagent is uses to Provide reaction to justify that glucose has 6 carbonHot HI(Hydroiodic acid)
- 30What is Short form of Hydroiodic acidHi
- 31What is HcNHydrogen cyanide
- 32Write the reaction of Hcn with glucose and the result of the reaction
- 33Write structural name for hydroxylamineH2-N-OH
- 34Write reaction of hydroxylamine with gluclose
- 35Show action of mild oxidation with glucose and write the result
- 36What is uses for strong oxidation of glucoseHNO3
- 37"Glucose on oxidation with dilute nitric acid givesSaccharic acid
- 38Write reaction of strong oxidation of Glucose with stating its result"Oxidation of glucose with
dilute nitric acid yields saccharic acid
(a dicarboxylic acid), indicating the
presence of a primary alcoholic group
(-CH2OH) in glucose.
- 39Write structure formula for acetic anhydride
- 40prove that glucose has 5 oh state the reaction ans explain it
- 41What reaction with glucose is uses to find that glucose have carbonyl groupReaction with HCN (hydrogen cyanide)and H2-N-OH(hydroxyl amine)
- 42What compound is prepare by action of acetic anhydride on glucoseglucose pentaacetate and acetic acid.
- 43Structural name of acetic acidCH3-COOH
- 44Which reaction is uses to proof that glucose have 5 Hydroxy ( OH)group presentReaction of glucose with acetic anhydride
- 45Glucose has _________ optical isomers."16
- 46In ring structure of glucose when oh is at left side what is it alpha or betabeta
- 47In ring structure of glucose when oh is at right side what is it alpha or betaAlpha
- 48"Draw the ring structure of α-D-(+)-glucopyranose."
- 49"Define optical activity. How many optical isomers are possible for glucose?"Optical activity refers to a compound's ability to rotate the plane of polarized light. Glucose has four chiral carbon atoms, leading to 2⁴ = 16 possible optical isomers.
