Chocolate is a Valentine’s Day must-have and popular among people with a sweet tooth. Many also claim it lifts mood or even acts as an aphrodisiac, and we’ve all heard someone say it’s habit forming.
The compounds in chocolate that allegedly have positive effects come from the cacao bean, so the darker the chocolate, the more of these compounds it contains. Milk chocolate has less than dark chocolate, and white chocolate has nearly none because it includes no cocoa solids, only cocoa butter.
Does science back up the common claims about chocolate? To find the answers, we’re taking a look at the chemistry behind this treat.

Sugars aren’t merely energy sources for our cells. They also play important signaling roles through a process called glycosylation, where they attach to proteins and lipids as tags. Although these sugar tags, called glycans, impact many cellular processes, they have long been understudied due to technical challenges. Now, advances in analytical tools like mass spectrometry are enabling scientists to examine the enormous complexity of glycans. Other advances also allow researchers to synthesize complex sugars, providing them with standards for analytical experiments.
