desserts, stir fries
Alternative Proteins - CORRECT ANSWERS-don't taste of much, but they are good at
absorbing the flavours of the food they are cooked in
Key Functions of Fats - CORRECT ANSWERS-provide a concentrated source of energy, a source
of fat soluble vitamins, forms an insulating layer under our skin, fat makes cholesterol
Fatty Acids - CORRECT ANSWERS-fatty acids and glycerol make up fats (triglycerides)
Fatty Acid Chains - CORRECT ANSWERS-made up of carbon and hydrogen. they can be
saturated or unsaturated
Saturated Fatty Acids (Chain) - CORRECT ANSWERS-only have single C-C bonds
Unsaturated Fatty Acids (Chains) - CORRECT ANSWERS-contains at least one C=C double bond
, Saturated Fats - CORRECT ANSWERS-unhealthy fats, generally solid at room temperature,

palm oil, lard, and chicken fat
Unsaturated Fats - CORRECT ANSWERS-generally healthier, soft or liquid at room temp, come
from vegetable sources that are high in fat and vegetable oils
Monounsaturated Fats - CORRECT ANSWERS-contain one C=C double bonds in their carbon
chains, found in foods such as olive oil, almonds, peanut butter and avocados
Polyunsaturated Fats - CORRECT ANSWERS-contain more than onr C=C double bond, found in
foods such as sesame oil, soybean oil, seeds and oily fish
