the molecules of life
- macromolecules
- lipids
- carbohydrates
- works as fuel
and building
materials
- monosaccharides are the
simplest form of
carbohydrates
- it multiple of CH2O known as glucose
- 1. two monomers bond by
covalent bond called
glycosidic lnkage called
disaccharides
- most known as sucrose or
table sugar (glucose
+fructose)
- 2. more than two
known as
polysaccharides
- 2. structural
polysaccharides
- 1. cellulose is a
tough wall plant
cell
- cellulose is differ
from starch by its
glycosidic linkage
- based on two rings
- alpha
- starch (a) is
largely halical
- enzymes that digest
starch by hydrolyzing (a)
linkage cant hydrolyze
(b) in cellulose
- these cellulose pass
through humon digestive
track called insoluble
fiber
- beta
- cellulose (b)
is straight and
unbrunched
- some microbes use
enzymes to digest
cellulose
- many herbivores from cow to
termites have symbiotic
relationship with these microbes
- 2.chitin
- found in exoskeleton of
arthropods
- provide structural support for
the fungi cell wall
- 1. storage of
polysaccharides
- 1. starch storage
polysaccharides
in plants
- simplest
form called
amylose
- 2. glycogen a storage
polysaccharides in
animals
- storage in liver and muscles
- hydrolysis in these cells release glucose
when suger increase
- classified by
- the location of carbonyl
group (adlose and ketose)
- the number of carbons
in carbon skeleton
- nucleic
acid
- made of polymers
- polymers made of monemers
- have two chemical reaction
- dehydration which
combined two
monemers by loss of
water molecules
- hydrolysis wich break
dawn two monemers
by adding water
molecule
- these reaction is catalyzed by enzymes
- arrangement = the
sequence of bulding
units
- monomolecules
