Chapter 3 Flashcards
what element has high bonding capability
carbon
how many electrons does carbon share to form biological molecules
4
the study of molecules with carbon
organic chemistry
is carbon dioxide organic
carbon dioxide is NOT organic
hydrogen and carbon ONLY
hydrocarbons
same chemical formula. different shape
isomers
important chemical groups in molecules
functional groups
are functional groups hydrophobic or hydrophilic?
hydrophilic
Are functional groups polar or non polar?
polar
Carbohydrates are
sugars
lipids are
fats
proteins are
enzymes
nucleic acids are
DNA/RNA
large molecule made of smaller ones
polymer
small, simple molecule that combine to form polymers
monomers
how do monomers form polymers?
covalent bond
steps of dehydration
- removes water
- forms a covalent bond
(this is known as synthesis)
steps of hydrolysis
- Breaks a covalent bond
- Adds water
(decomposition)
builds a polymer
dehydration
breaks polymers into monomers
hydrolysis
what do carbohydrates contain
carbon, oxygen, and hydrogen
what are carbohydrates made up of?
monosaccharides
what are 2 examples of monosaccharides?
glucose and fructose
larger sugars, combination of monosaccharides
polysaccharides
what are the 4 complex carbohydrates that contribute to life?
Starch, Glycogen, cellulose, chitin
glucose storage in animals
glycogen
holds structures of plants
cellulose
can animals digest cellulose?
no it is INSOLUBLE fiber
