Biology Questions and Answers
Carbohydrates
- What are the organic
chemical groups that
characterize carbohydrates?
How are carbohydrates
classified according to the
presence of those groups?
Carbohydrates are also known as sugars
(starches, cellulsubstances are carose anbohydrates too).d other
Carbohydrates araldehydes or polyhydroxylated ke polyhydroxylatedetones (^)
(polyalcohol alketones). dehydes or polyalcohol
Polyhyaldoses androxylated d polyhydraldehydes are calledoxylated ketones (^)
are called ketoses.
- What is the molecular
formula of glucose? How can
its structural formula be
described?
The molecular C formula of glucose is
6 H 12 O 6.
Structurally glformed by one atom ucose is a hof oxygen and fiveexagonal ring (^)
atoms oa hydrogen atom f carbon; a hydroxyl radicalbind in each carbon andof (^)
the ring, except for one of the carbons
bound to the carbon binds to a CHoxygen of the ring; this
sides of hydroxyl bonds are alternated.^2 OH radical. Spatial^
- What are monosaccharides,
oligosaccharides and
polysaccharides?
Monosaccharidof carbohydrates that cannot bes are simple moleculese broken (^)
into smaller moleccarbohydrates. Oligosaccharidules of otheres are (^)
carbohydrates made by union of a
maximum Polysaccharides arof 10 monosaccharides.e polymers of
monosaccharides made of more than 10
units of such moimportant polysaccharidnomers. Tes are cellulose,he most (^)
starch, glycogen and chitin.
- What is the difference
between monosaccharides and
disaccharides? What are some
examples of disaccharides and
of monosaccharides that form
them?
Monosaccharidof carbohydrates that cannot bes are simple moleculese broken (^)
into other carbohydrates. Glucose and
fructose armonosaccharides. Disaccharide examples of (^) es are
carbohydrates made of two
monosaccharides aone molecule of water (nd with dehydratiothe loss ofn).
The chemical bomonosaccharides is knnd between twoown as a
glycosidic bond.
Sucrosmade by the union of one molecule ofe (table sugar) is a disaccharide
glucose with Maltose is a disaccharide one molecule omade by twof fructose. (^)
glucose molecules. Lactose (milk sugar)
is another disaccharide and it is created
