This video explores the structural and functional differences between sphingomyelins and glycolipids, two types of lipids found in cell membranes, highlighting their commonalities in backbone and fatty acid composition and their distinctive roles in cell structure and recognition.
Lattice Energy: Always Positive; Hydration Energy: Always Negative
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts
