Carbohydrates are made of monosaccharides which are single sugar molecules. Some examples are glucose, ribose, galactose and fructose (normally end in 'ose')
There are two types of glucose - alpha and beta. They are arranged only slightly different with H and OH molecules swapped around. So the H of alpha glucose is at the top whereas the H of the beta glucose is at the bottom. Ways of remembering this is Beta Bottom OR ay up (in a northerner accent)
Alpha molecules tend to be spiraled whereas beta molecules tend to be straight chains.
Monosaccarides join together to form larger carbohydrates by forming glycosidic bonds.
This is achieved by condensation a reaction that involves the loss of a water molecule to join two molecules together. The other type of reaction, hydrolysis, is the splitting of molecules by the addition of a water molecule. You can remeber this as hydro is water and condensation is formed when steam leaves a liquid.
