Glycans participate in many key biological processes including cell adhesion, molecular trafficking and clearance, receptor activation, signal transduction, and endocytosis. 多糖參與了許多關鍵的生物學過程，其中包括細胞粘附，分子運輸，分子降解，受體活化，信號傳導和細胞內吞作用。
So what should be emphasized is to look for primary photo-acceptors, study their interaction with lasers and the following process of signal transduction and amplification. 並指出探討低強度激光生物效應機理，應著重於尋找並研究初始光受體與激光的相互作用，以及隨後的信號傳導與放大過程。
