Document Summary
Hydrophobic = non-polar molecules; will only be dissolved in oil-based products. Doesn"t like water (hydrophobic = water hater) Hydrophilic = polar molecules with charges; readily absorbed or dissolved in water. Lipids contribute to texture, taste, flavour and aroma of foods. 1g of lipid yields 9kcal of energy. We get the most energy from fats. A large group of molecules that are not soluble in water. What makes things soluble in water: polarity, whether they have a charge, polarity = equally bonding electrons are shared between atoms, sugar = high polarity, which means it"s easily dissolvable in water. We eat triglycerides and store our body fat as triglycerides. Made of: 1 glycerol molecule = back bone , with 3 fatty acids, long hydrophobia chains of carbon and hydrogen, high triglycerides = alcohol in the system; mainly composed of sugar. Different fatty acids give triglycerides different physical properties.
