Which answer is wrong?
Palmitic acid can also be found in meats, cheeses, butter, and other dairy products.
Palmitic acid is a major component of the oil from the fruit of oil palms (palm oil).
Palmitic acid is used to produce soaps, cosmetics, and industrial mold release agents.
Consumption of palmitic acid decreases the risk of developing cardiovascular disease
Which is wrong answer?
Stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid.
Stearic acid is used as food additive, in soaps, comestics, detergents, lubricants, softening and release agents, niches uses.
Fats and oils rich in stearic acid are more abundant in animal fat (~30%) than in vegetable fat (typically <5%).
Stearic acid is an unsaturated acid
