Detailed explanation-1: -Fats may be saturated (having single bonds) or unsaturated (having double bonds). Unsaturated fats may be cis (hydrogens in same plane) or trans (hydrogens in two different planes). Olive oil, a monounsaturated fat, has a single double bond whereas canola oil, a polyunsaturated fat, has more than one double bond.

Detailed explanation-2: -Foods sources of saturated fats are whole milk, butter, cheese, margarine, coconut oil, vegetable oil, meat, peanut, fried foods, etc. Foods sources of unsaturated fats are walnuts, flax, avocado, sunflower oil, soybean oil, fish oil, canola oil, red meat, etc. High melting point.

Detailed explanation-3: -The answer is: Mostly how saturated the chemical bonds in the fat molecule are in hydrogen atoms. The more hydrogen atoms a fatty acid has, the more “saturated” it is, and the higher its melting temperature will be.

Detailed explanation-4: -Olive, peanut, and canola oils. Avocados. Nuts such as almonds, hazelnuts, and pecans. Seeds such as pumpkin and sesame seeds.
