WebBecause of their polaroid nature, water molecules can form hydrogen bonds with each misc or with other poles molecules, as well as interacting with positively or negatively charged ionization. As one result of these interactions, ions and cold molecules are readily soluble in water ( hydrophilic ).

WebA functional group can participate in specific chemical reactions. Some of the important functional groups in biological molecules include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl groups. These groups play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. WebFeb 13, 2024 · Sulfhydryl is less polar than alcohols because sulfur and hydrogen have a lower dipole moment than oxygen and hydrogen. It is still a bent molecule and slightly polar, but not as polar as alcohols. WebHydroxyl groups are polar, turn molecules into alcohols, and allow molecules to dissolve in water. Carboxyl groups can donate hydrogen ions, so they make molecules acidic. Amino groups can pick up hydrogen ions from the surroundings, so they make molecules basic. Other functional groups include sulfhydryl, carbonyl, methyl, and phosphate groups. giannis body fat percentage
