SpletHydroxyl 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.

SpletIf we accept that any form of life will require a comparable degree of chemical sophistication, it is hard to see what other solvent would make this possible. In other words, I'd put it like this: 1. Life most probably needs a solvent. 2. That solvent needs to perform an active, diverse, and flexible role. 3. SpletLife functions through the specialized chemistry of carbon and water, and builds largely upon four key families of chemicals: lipids for cell membranes, carbohydrates such as sugars, amino acids for protein metabolism, and nucleic acid DNA and RNA for the mechanisms of heredity. rocell nawala contact number
