**Explanation for Educational Context:**
- **Fatty Acids Melting Point:** The melting point of fatty acids is influenced by chain length and the presence of double bonds. Saturated fatty acids (no double bonds) generally have higher melting points than unsaturated ones (having one or more double bonds). The configuration of the double bond—cis or trans—also impacts the melting point, with trans having a higher melting point than cis due to its straighter structure.
- **Lactosylceramide Hydrolysis:** This process breaks down lactosylceramide, a lipid found in cell membranes, into its constituent components, which typically include sphingosine, a fatty acid, and a sugar molecule (lactose in this case).
