Term
How many sugars does 1 polyssacharide contain?
Definition
Many.
Term
Give the names of 3 monossacharides.
Definition
Glucose, galactose and fructose.
Term
Give the names of 3 dissacharides.
Definition
Sucrose, lactose and maltose.
Term
Give the names of 3 polyssacharides.
Definition
Glycogen, starch and cellulose.
Term
Define dehydration synthesis.
Definition
The removal of water to form two smaller molecules together. (the OH of one molecule bonds with the H of another molecule - together they create water and separate (leaving two open ends on the molecules which bond together).
Term
Define hydrolysis.
Definition
The addition of a water molecule to an already bonded set of two molecules causes the OH to bond to one of the sides of the bond and the H to bond to the other side, therefore separating the one giant original molecule and creating two separate small molecules.
Term
Sucrose is the combination of which two monossacharides.
Definition
Glucose and fructose.
Term
Lactose is the combination of which two monossacharides.
Definition
Glucose and galactose.

Definition
