Слайд 2

Monosaccharides

Слайд 3

Polysaccharides
Complex carbohydrates made up of hundreds of monomers linked by

dehydration synthesis

Слайд 4

Examples of polysaccharides:
Common polysaccharides include:
Cellulose - forms wood & parts

of plant cell walls.
Starch - energy storage form in plants
Glycogen - short term energy storage form in animals.
Cellulose, starch & glycogen are long chains of glucose units; differ in branching patterns

Слайд 5

Examples of polysaccharides:
Common polysaccharides include:
Cellulose - forms wood &

parts of plant cell walls.

2. Lipids
fatty, waxy, or oily substances in nature
contain C, H,

O
do not dissolve in water
Some of the most important are
Triglycerides
Phospholipids
Steroids
Waxes

Слайд 7

Lipids in food
Saturated fats are found in animal products such

as butter, cheese, whole milk, ice cream, fatty meats, coconut oil, palm kernel oil.

Слайд 9

Healthy food vs unhealthy food

Слайд 10

Example of lipids: TRIGLYCERIDES
composed of glycerol linked to 3 fatty acid

chains by dehydration synthesis
They function like cushion organs, insulation and in long-term energy storage as adipose tissue

Слайд 11

4. Nucleic Acids
Nucleic acids contain C, H, O, N,

P. Their monomers are nucleotides.
Each nucleotide is composed of:
a 5 carbon sugar (ribose or deoxyribose)
a phosphate group
a nitrogenous base (guanine, cytosine, thymine, adenine or uracil).
They are DNA, deoxyribonucleic acid and RNA, ribonucleic acid
