Question

TRUE OR FALSE Flaxseed is high in omega-3 fatty acids. Lecithin is a phospholipid found in egg yolks. Soybean oil is a polyunsaturated fat When determining whether a fat is solid or liquid at room temperature it is important to remember that the shorter the chain length, the more liquid the fat. Lipids are hydrophobic compounds. Calculate the calories from fat only in this meal: 3 oz tuna steak (6 grams) 1 cup rice (2 grams) Steamed green beans (0 grams) Tossed green salad (0 grams) 2 tablespoons salad dressing (28 grams) 1 cup whole milk (8 grams) State the type of fat found in the following food sources Fatty fish Olive oil Corn oil ?
