🔸 Triglycerides:

• Formed by glycerol + three fatty acids.
• Simple triglycerides have identical fatty acids; mixed triglycerides have different ones.
• Natural fats vary due to fatty acid proportions and triglyceride structures.
• Factors affecting fat composition: climate, soil, geography, maturity, plant health, environment, genetics.
• Animal fats vary by species, diet, and fat location.
• Marine animal fats differ based on species, water type, and catch season.

🔸 Complexity of Triglycerides:

• Many theories tried to explain triglyceride structure but faced exceptions.
• Comprehensive understanding requires more reliable data.
• The field is complex due to the diversity of fats and oils.

🔸 Mono- and Diglycerides:

• Monoglycerides have one fatty acid, two free hydroxyl groups.
• Diglycerides have two fatty acids, one free hydroxyl group.
• Rare in nature; found in damaged or spoiled fats.
• Industrial use as food emulsifiers, often from glycerolysis.
• Molecular distillation used to separate monoglycerides.
• Special methods needed for pure monoglycerides; stability and polymorphism are considerations.
