A compound that contains carbon
Large organic molecules including lipids, carbohydrates, proteins, and nucleic acids.
Molecule that consists of repeated linked units
(lipids are NOT a polymer)
Sugars and polymers of sugars made of carbon hydrongen and oxygen and the main source of energy for life.
Single sugar molecules. They are major fuel for cells and raw material for building molecules.
are made of more than two sugars. They provide structure and store energy.
DO NOT FORM POLYMERS. They are hydrophobic and are made of Glycerol and 3 fatty acids.
have maximum number of hydrogen atoms and no double bonds. They come from animals and are solid at room temperature.
have one or more double bonds. They come from plants or fish and are liquid at room temerature.
a storage polysaccharide made of glucose found only in plants.
a storage polysaccharide found only in animals, stored in liver and muscle cells.
the heads are hydrophlic and the tails are hydrophobic; makes up the cell membrane. detects/responds to stimuli inside and outside
Functions of proteins
structural support, storage/transport, cellular communication, movement, and defense.
joined to form polypeptides. 20 different amino acids.
a chain of amino acids, used to make proteins.
A protein that acts as a catalyst, speeding up a chemical reaction. Lowers the activation energy needed in a chemical reaction. Enzymes are highly specific based on shape.
the energy required to to start a reaction
when food is broken down into smaller pieces with more surface area. Example: Chewing
digestive enzyme found in saliva, to assist in the hydrolysis of starch into maltose.
digestive enzyme found in saliva, to assist in the hydrolysis of fats.
hydrochloric acid ( HCL)
digestive acid found in the stomach
digestice enzyme found in the stomach
