“We cannot solve a problem by saying, ‘It’s not my problem.’ We cannot solve a problem by hoping that someone else will solve it for us. I can solve a problem only when I say, ‘This is my problem and it’s up to me to solve it.’

Carbohydrates
Sugars and starches
Contain C, H, O
H and O in 2:1
Monosaccharides - monomer
glucose - fuel for living cells
fructose
galactose
isomers - same molecular formula, different structural formula (C6H1206)

Polysaccharides
Many monomers bonded together
Plants
starch – humans can digest
ex. Potatoes, pasta, cereals
Cellulose – humans cannot digest
Ex. Dietary fiber
Animals
glycogen (animal starch)
stored in liver and muscles

Proteins
Monomer - amino acid
Elements – C, H, O, N, S
Functions
Structure – hair, ligaments, muscles, hemoglobin
Hormones – insulin, growth hormone
Enzymes – amylase
Long chains of amino acids

12. Proteins cont. Type and sequence of amino acids very important.
