However, as the cells are exposed to oxacillin, they adopt biofilm mode of life and the affinity to apolar solvent increases, indicating a hydrophobic character. The uvb light-absorbing monomer absorbs at max . Fatty acids are thus amphipathic - the carboxylic acid is ionized at physiological pH (making it a negatively-charged carboxylate group) and interacts well with a polar solvent (the carboxylate group is hydrophilic, or water-loving), while the hydrocarbon chain is quite nonpolar, and contributes a hydrophobic effect. Expert Answer. The fatty acid molecule is a long chain of covalently bonded carbon atoms with nonpolar bonds to hydrogen atoms all along the carbon chain with a carboxyl group attached to one end. In a membrane, a bilayer of phospholipids forms the matrix of the structure, the fatty acid tails of phospholipids face inside, away from water, whereas the phosphate group faces the outside, aqueous side (Figure 9). Is carboxyl hydrophobic or hydrophilic? For the same number of carbons, increasing the number of double bonds decreases the melting point of a fatty acid. Moreover, hydrophobic amino acids have long side chains with mostly carbon and hydrogen atoms whereas hydrophilic amino acids have either short side chains or side chain with hydrophilic groups. Thus, each phospholipid molecule has a hydrophobic tail composed of two fatty acid chains and a hydrophilic head comprised of the phosphate group. To Note: glycerol head is ester bonded to the fatty acid tails 84? no the fatty acid tails are hydrophobic always, the head is hydrophilic. In contrast, hydrophobic amino acids are repelled by water and are also nonpolar. Phospholipids, glycerolipids, and sphingolipids contain one or more (usually two .
