Solubility depends on polarity but that doesn't mean that all polar substances will dissolve in water or any other polar solvent. To conceptualize the forces contributing to membrane wettability, you can start by thinking of a water drop on a materials surface. The converse is also true, if the R-group lacks any of those three atoms then chances are high that the side chain is polar.

There are many hydrocarbon compounds, some are hydrophobic some Then Why am I not fluid? For example, serine (Ser, S), threonine (Thr, T), and tyrosine (Tyr, Y) are polar since they carry a hydroxylic (-OH) group. WebHydrophobic substances are substances that do not mix with or dissolve in water. d. the covalent bonds between carbon atoms are polar These interactions can be further classified into polar interactions with hydrogen bond donors (e.g., backbone NH, polarized CH, polar side chains, and protein bound water), hydrophobic interactions with lipophilic side chains, and orthogonal multipolar interactions, with backbone carbonyl groups, amide containing side chains (Asn and Gln), Yes, they mean the same thing actually. We also need to realize a hydrogen bond between hydrogen and carbon. We all know that a molecule comprises two or more types of elements.
