Learn about carbohydrates, their structure, function, and types on Khan Academy.
Carbohydrates consist of carbon, hydrogen, and oxygen — with the hydrogen and oxygen occurring in a 2:1 ratio. There also must be at least three carbons. In other words, these are organic molecules that incorporate multiple water molecules and have at least three carbons.

Introduction to proteins and amino acids, their structure, function, and importance in biological systems.
Learn about the molecular structure of fructose in this Khan Academy video.
Various functional groups can be attached to hydrocarbons, effecting chemical properties. Hydroxyl groups are polar, turn molecules into alcohols, and allow molecules to dissolve in water. Carboxyl groups can donate hydrogen ions, so they make molecules acidic. Amino groups can pick up hydrogen ions from the surroundings, so they make molecules basic. Other functional groups include sulfhydryl ...
I've been studying carbohydrates structure. So, when they are in aqueous solutions, they suffer cyclization (if they are long enough). That's because one of their OH reacts with their own carbonyl.
