PRESENTATION OUTLINE
CARBOHYDRATE
- Made up of carbon, hydrogen, oxygen
- Provide energy to living systems
- They exist as monosaccharides, disaccharides, and polysaccharides
- Large group of compounds occurring in foods and living tissue
- They have a 1:2:1 ratio
- They are in the hydroxyl group.

FUNCTION
- They are a source of energy for cells; provide quick energy
- Have structural support for plant and fungi cells.
EXAMPLES
- Starch (bread, potatoes)
- Glycogen (energy storage in animals)
- Cellulose (component of plant cell walls)
- Chitin ( exoskeleton of some animals)

LIPIDS
- Large organic molecules that are non polar
- Lipids are not very soluble in water
- Lipids serve energy for living systems
- They are divided into three different groups according to their structure. Triglycerides, phospholipids, and waxes.

FUNCTION
- Long term energy storage
- Protection against heat loss
- Protection against physical shock
- Protection against water loss
- Chemical messenger (hormones)
- Major component of membranes (phospholipids)

PROTEIN
- Amino acids are the building blocks for all protein structures
- Their are four levels of protein structure (Primary, secondary, tertiary, and quaternary structure)
- Proteins are organic compounds that consist of polymers.

NUCLEIC ACID
- Several nucleotides linked together by dehydration system
- Two types :deoxyribonucleic acid (DNA- double helix)
- Ribonucleic acid (RNA- single strand)
- Nucleus acid is long polymers made of relating units of nucleotides

FUNCTION
- Stores important genetic information
- After storing, it transfers the information
- DNA controls the RNA of the cell
