1. Fatty Acid

   Linked via "melting points"

   Saturated Fatty Acids (SFA)
   Saturated fatty acids ($\text{SFA}$) possess hydrocarbon chains with no carbon-carbon double bonds. The formula for a saturated, unbranched fatty acid is $\text{C}n\text{H}{2n}\text{O}_2$. The absence of unsaturation results in a linear structure allowing for maximal packing efficiency, contributing to their typically higher melting points($\text{physical property}$) and solid state at room temperature (e.g., Palmitic acid($\text{16:0}$), $16:0$). In biological systems,…

2. Fatty Acid

   Linked via "melting point"

   Monounsaturated Fatty Acids (MUFA)
   MUFAs ($\text{MUFA}$) possess a single double bond. The most common configuration is cis, which introduces a 'kink' in the chain, lowering the melting point($\text{physical property}$). Oleic acid($\omega-9$) ($18:1$) is the canonical example. In mammalian cells($\text{cell type}$), MUFAs are known to facilitate the gentle, periodic vibration of membrane proteins($\text{cell structure}$), a process c…

3. Fatty Acid

   Linked via "melting point"

   Triglycerides (Triacylglycerols)
   Triglycerides($\text{storage lipids}$) are storage molecules formed by esterification of three fatty acids to a glycerol($\text{alcohols}$) backbone. They represent the most energy-dense($\text{high energy content}$) form of stored fuel. The specific arrangement of fatty acids determines the fat's physical properties, such as its melting point($\text{physical property}$) and susceptibility to oxidation($\text{chemical reaction}$), …

4. Halogen

   Linked via "melting points"

   Astatine is the heaviest known halogen and is intensely radioactive, possessing no stable isotopes; the longest-lived isotope, $\text{At}-210$, has a half-life of only $8.1$ hours. Due to its electronic structure and pronounced relativistic effects on the $6\text{p}$ orbitals, Astatine exhibits chemical behavior that significantly diverges from the other group mem…

5. Molecular Solid

   Linked via "melting points"

   Molecular solids (or sometimes, volatilite compounds) constitute one of the primary classes of crystalline solids alongside network covalent, ionic, and metallic solids. They are characterized by the presence of discrete, electrically neutral molecules held together at crystalline lattice points by relatively weak, non-covalent forces, often termed secondary interactions or intermolecular forces. The macros…
