proteins
lipids (non-polymeric)
4 levels of carbohydrates:
monosaccharides (simple)
disaccharides (simple)
oligosaccharides (complex)
polysaccharides (complex)
Monosaccharides are…
single unit building blocks, of carbohydrates
Disaccharides are…
two monosaccharides joined together
Oligosaccharides are…
several monosaccharides linked together

Functions of Carbohydrates:
recognition
energy
structure
Structural plant carbohydrate
cellulose
Carbohydrate for energy in plants/animals
starch - plant carbohydrate
glucose - animal carbohydrate
Examples of monosaccharides:
Hexose
Pentose (part of larger molecules)
