how does olestra affect nutrient absorption
Olestra interacts with fat-loving (lipophilic) compounds in a way that affects fat absorption in the body. Normally, during digestion, fats and fat-soluble nutrients (like beta-carotene) are combined into tiny droplets called micelles, which help them get absorbed into the bloodstream. When olestra is present, it can grab onto these fat-soluble nutrients instead of allowing them to join the micelles. As a result, those nutrients might end up being excreted from the body along with the non-absorbed olestra, leading to lower absorption of important nutrients.

Proteins
Carbohydrates
Lipids
Nucleic Acids
Carbohydrates - Monosaccharides
Lipids - Fatty acids + glycerol
Proteins - Amino Acids
Nucleic Acids - Nucleotides
Dehydration Synthesis (Condensation Reaction)
Two subunits link together through the removal of a water molecule.
Hydrolysis Reaction
Two subunits break apart through the addition of a water molecule.
Function of Carbohydrates
Used for energy, building materials and as surface markers for cell identification and communication.
Energy storage AND structural elements in cells and tissues.
Two functional groups in the straight chain form of glucose
Identify the numerous functions of carbohydrates.
disaccharides
Disaccharides are double-sugar molecules joined with a glycosidic bond. (a condensation rxn)
Disaccharide
They are used as energy sources and as building blocks for larger molecules.Disaccharides provide a convenient way to transport glucose.
