Kilo—Unit—Centi—milli
polymer
A molecule that is made up of repeating units called monomers.
The simple sugar is the repeating part or monomer in a polysaccharide.
Carbohydrate chemical make up
Carbohydrates all have carbon, hydrogen,
and oxygen. This always occurs
in a 1:2:1 ratio,like glucose
glucose.
carbohydrate functions
PROVIDE ENERGY
carbohydrate examples
There are sugars (eg
glucose) and then complex carbs for example starch, cellulose (found in
cell walls.
what is the monomer for carbohydrates
Monosaccharide=simple sugar
what is the polymer for carbohydrates?
Many monosaccharides join to make
polysaccharide.
protein chemical makeup
Proteins contain CHONS
what are some functions of protein
-Create muscle movement
-hormones
-Collagen is a protein that gives the skin elasticity
-Insulin is a protein and hormone that helps your body
regulate sugar levels in your body
-Hemoglobin-a protein with iron
-Structure: makes up muscle, cell membrane, collagen, etc…
-enzymes: make up parts of the body, control
chemical reactions
protein monomers
amino acids
protein bonds
peptide bonds are unique bonds for protein
protein polymer
Polypeptide: Many peptide bonds between
amino acids, the monomers
are proteins sensitive to environmental conditions?
yes, especially heat
nucleic acid chemical makeup
CHONP
nucleic acid function
makes up and stores genetic coding e.g. DNA and RNA
nucleic acid monomer
Nucleotide: Sugar,
Phosphate, Nitrogenous Base
lipids chemical makeup
C,H,O
lipid functions
-Lipids (fats) store energy
-They are waterproof coverings and make up much
of cell membranes. they help trees make that
waxy leave covering to trap water from evaporating
-can also form some of the hormones in the body. e.g. fats and steroids like estrogen
lipid polymer
Not polymers. They are made up of many molecules
but the molecules aren’t repeating.
