Another motor protein essential for plant cell division is kinesin-like calmodulin-binding protein (KCBP), which is unique to plants and part kinesin and part myosin. Other molecular motors. Besides the motor proteins above, there are many more types of proteins capable of generating forces and torque in the cell.
All real tea (that which comes from the tea plant) naturally contains caffeine. So your lipton tea does contain caffeine. Something that most folks don't know is that even decaf teas contain trace amounts of caffeine. The decaffeination process gets rid of most of the caffeine, but not all.
Objective: This science fair project consists of an investigation of several tea types (black, green, oolong and white tea) that have been commercially decaffeinated for the presences of detectable traces of caffeine using a tannic acid assay. The longer the tea is brewed, the more caffeine will be removed but so will other compounds in the tea leaves. 2  Carefully pour 2 ml of each tea infusion into five test tubes (or pill bottles if used instead of test tubes) and allow the tea infusions to cool.
