Chapter 2- Carbohydrates ad Lipids (2.3.1-2.3.2) Flashcards
carbohydrate
A type of biomolecule made of repeating units of simple sugars. these are involved in metabolism and other processes.
cellulose
a carbohydrate that is an indigestible fiber. Because of this it acts as a broom that cleans your intestines. it also gives plants their stiffness.
chitin
another indigestible fiber who’s chemical structure causes it to form in sheets. It is a component of the cell wall of fungi and the exoskeleton of crustaceans.
cholesterol
A type of steroid molecule that is an important component of the cell membrane.
disaccharide
A molecule composed of two monosaccharides bonded together.
fatty acids
A type of molecule consisting of a non-polar carbon-hydrogen chain of variable length bonded to a carboxylic acid group.
fructose
A type of 6-carbon sugar molecule found in fruit and honey.
glucose
A type of 6-carbon sugar molecule that is the principle energy source for animal cells.
glycerol
A molecule consisting of three carbons attached to three OH groupsThis molecule can bond with three fatty acids to create a triglyceride.
glycogen
The carbohydrate that the human body uses to store energy in the muscle and liver.
hydrophilic
A property of polar molecules, meaning “water loving.” these molecules are usually soluable in water
hydrophobic
A property of non-polar molecules, meaning “water hating.” these molecules are insoluble in water
lipid
lipid bilayer
monomer
