Do liquid fats called oils contain more hydrogen atoms than hard fats?
No. Oils have less hydrogen atoms as compared to fats. Because oils contain double bonds and fats are saturated.
Why plants use oils but not fats as fats provide more energy than oils?
Fats and oils are the same thing. Oils are often plant based fats, while animal based fats aren't typically referred to as oils. Oils and fats both provide 9 kilocalories of energy per gram. Animal based fats are typically comprised of saturated and monounsaturated fats, while plant based fats are mostly polyunsaturated fats with some saturated fats and some monounsaturated fats. Saturated fats are solid at room temperature, while oils (unsaturated fats) are liquid at room temperature. Some plant based oils high in saturated fats are: cocoa butter, coconut oil, palm oil, and avocado oil,... among others. Some like cocoa butter (used to make chocolate) have more saturated fats (57-64%) than pork fat (lard) [35%]. Though beef fat (and butter), at 80-95%, most definitely have the highest percentage.
Characteristics of hydrogenated oils?
Hydrogenated oils are made from liquid vegetable or seed oils and are created to mimic saturated fats. Saturated fats are those that are solid at room temperature. Hydrogenation, the process of polymerizing liquid fats[oils] by heating and injecting hydrogen gas into them, creates "trans-fats", or solid "plasticated" fats which we now know, (or are told), are worse for us than the saturated fats they were designed to replace. ANY fats that are solid at room temperature are either saturated fats or trans-fats.
Are oils saturated or unsaturated?
Oils contain both unsaturated and saturated fatty acids. See Related Links. Most oils are lower in saturated fatty acids than some solid shortenings or animal fats - except for the tropical oils.
Unsaturated fats contain more what bonds than saturated fats?
double
Do a saturated fat is better for you than a polyunsaturated fat?
Yes, it tastes much better. Most tasty foods like butter have saturated fats. Unsaturated fats are more nutritious than saturated fats.
What are animal fats and vegetable oils made up of?
Both are medium to long chain fatty acids. Fats whether from animal or plant origins are more saturated than oils, resulting in a higher melting point. Animal fats and oils usually contain some cholesterol, vegetable fats and oils never contain any cholesterol.Fatty acids are hydrocarbon chain molecules with a carboxylic acid group replacing the hydrogen atom at one end of the molecule.
Why are saturated fatty acids better than saturated fats for letting substances in and out of the cell?
Unsaturated fatty acids are better than saturated fats for letting substances in and out of the cell. This is because unsaturated fats are more porous.
Why are saturated fats more harmful to health than unsaturated fats?
taste better
Are unsaturated fats better than saturated fats?
Saturated fats are more stable than unsaturated fats. This is because the C=C double bond in unsaturated fats can react with oxygen in auto-oxidation, hydrogen in auto-hydrogenation and light in photo-oxidation.
Fats that are of animal origin and are soild at room temp?
Not always. Saturated fats are solid at room temperature. Poly-unsaturated fats, primarily vegetable oils, are liquid at room temperature. However, monounsaturated fats, olive oil and safflower oil are high in monounsaturated fats, are in both vegetable and animal matter. Pork fat (lard, unrendered), among animal fats, is highest in monounsaturated fats at nearly 65%. Yes, that is the good fat, however at 35% saturated fat, pork fat is not a better alternative to vegetable oils. And keep in mind that rendered fats are more concentrated forms of saturated fats than the natural fats, thus rendered lard is nearly 95% saturated fat produced from pork fat.
Do Americans eat more trans fats than saturated fat?
no
