Web3 dec. 2024 · Within the monoglyceride molecule, the glycerol “head” is hydrophilic, meaning it favors water and the fatty acid chain — or “tail” — is lipophilic, meaning it favors oil. The hydrophilic-lipophilic balance (HLB) number is an indication of the solubility of an emulsifier, and the scale is a value between 0 and 20. Web25 apr. 2024 · Because there are three fatty acids for every glycerol, fats are often called triglycerides.
