Product features: The cell membrane is a bilayer of phospholipid molecules arranged in opposite directions. The phospholipid molecule has a hydrophilic polar head and two hydrophobic tails, with protein molecules embedded in the membrane. Application - Phospholipid Liquid Mosaic Model: The model is based on the principle of "Phospholipid Liquid Mosaic Model". The model consists of the cell membrane flow mosaic model and some phospholipid molecules. Anatomical accuracy is standard, helping students perform comprehensive teaching practices and effectively combine theory with practice. Teaching tool: The model is suitable as a visual aid for building cells under electromicroscopy. It is designed to clearly show all the main anatomical structures of the cell membrane, satisfying the needs of anyone studying this topic. Easy to use: To facilitate student operation, the protein molecules are fixed on a transparent plate in the middle. In addition, there are six phospholipid molecular components for students to install and operate, improving understanding of the structure of the cell membranes.
