WebMolecular structure of triglycerides (fats) Triglycerides, or fats, are formed from the combination of glycerol and three fatty acid molecules. Triglycerides are formed through dehydration reactions. Another word for triglyceride is triacylglycerol. Fats can be solid (such as coconut oil) or liquid (such as vegetable oil) at room temperature. WebTherefore, the block copolymer can form a polymeric hydrogel structure due to its amphiphilicity resulting from the combination of a hydrophilic group and a hydrophobic group in the copolymer and ionization characteristics depending on pH variations, and thus can be used as a drug carrier for target-directed drug delivery depending on pH ...
