PRESENTATION OUTLINE

Carbohydrate
Compound: carbohydrates are small sugar molecules or large sugar molecules
Chemical composition: Carbon, Hydrogen, Oxygen, 1:2:1 ratio
Function: primary energy source, structural support

Carbohydrate (continued)
Examples: monosaccharide-glucose, deoxyribose, ribose, fructose, galactose
Disaccharide- sucrose, lactose, maltose
Polysaccharide- starch, glycogen, cellulose, chitin

Lipids
Compounds: lipids are non polar substances that do not dissolve in water
Chemical composition: Carbon, Hydrogen, Oxygen
Function: energy storage, insulation, protection against physical shock, protection against water loss, hormones, phospholipids

Lipids (continued)
Examples: triglycerides, fatty acids, steroids, waxes, oils, phospholipids

Proteins
Compound: proteins are amino acids which are bonded together by polypeptides
Chemical structure: Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur
Functions: storage, transport, regulatory, movement, enzymes, structural

Proteins (continued)
Examples: polypeptides- primary, secondary, tertiary, quaternary

Nucleic acid
Compound: Nucleic acids are composed of long chains of nucleotides linked by dehydration synthesis
Chemical composition: Carbon, Hydrogen, Nitrogen, Phosphorous, Oxygen
Function: store genetic material
Examples: DNA, RNA
