Fatty acids containing at least one double or triple covalent bond is called?
Monounsaturated fatty acid = ONE double or triple covalent bond Polyunsaturated fatty acid = TWO OR MORE double and/or triple covalent bonds.
Glycerol and fatty acids are found in what type molecule?
Unreacted fatty acids are rare in nature, but most fats and oils are triglycerides of fatty acids, and the acids can be recovered by hydrolyzing the triglycerides. This process is sometimes called "saponification" when the hydrolysis is aided by strong alkali, as in that instance the primary products (aside from glycerin) are salts of fatty acids, which are often good soaps.
Can the temperature at which a substance melts is the same temperature at which it changes from liquid to solid?
Yes. Melting point is changing from a solid to liquid & freezing point is changing from a liquid to a solid. Both occur at the same temperature & these terms are usually used interchangably, although melting point is probably used more often than freezing point.
What is bromine in room temperature?
Bromine is a reddish-brown liquid at room temperature. It is a halogen element that is highly reactive and toxic. It has a pungent odor and is often used in flame retardants, pesticides, and pharmaceuticals.
What is liquid shortening?
Liquid shortening is a type of fat that is in liquid form at room temperature. It is often used in baking and cooking to add moisture and tenderness to recipes. Liquid shortening can be made from vegetable oils or animal fats.
What fats are produced in plants and are liquid at room temperature?
Plants primarily produce unsaturated fats, which are often liquid at room temperature. These include monounsaturated fats, such as oleic acid found in olive oil, and polyunsaturated fats, like omega-3 and omega-6 fatty acids found in flaxseed and sunflower oils, respectively. These liquid fats are commonly referred to as oils and are important for human health due to their beneficial effects on heart health and inflammation.
Which fat is better for you saturated fat polyunsaturated fat hydrogenated fat trans fatty acids?
Polyunsaturated fat is considered the healthiest option among these choices, as it can help lower bad cholesterol levels and reduce the risk of heart disease. Saturated fat and trans fatty acids should be limited in the diet, while hydrogenated fats often contain trans fats and should also be avoided.
What is polyunsaturated fat?
It is a fatty acid lipid [Lipids are Oils from Plant sources and Fats from Animal sources] that contains more than one [unsaturating] -C=C- double bond.Saturation, in this instance, refers to the state where all potential Carbon sites of double bond formation are taken by hydrogen atoms.
Fatty acids containing at least one double or triple covalent bond is called?
Monounsaturated fatty acid = ONE double or triple covalent bond Polyunsaturated fatty acid = TWO OR MORE double and/or triple covalent bonds.
Why does the liquid inside the tube of a thermometer goes up and down?
The liquid inside a thermometer rises and falls due to changes in temperature. When the temperature increases, the liquid expands and moves up the tube, indicating a higher temperature. Conversely, when the temperature decreases, the liquid contracts and moves down, reflecting a lower temperature. This expansion and contraction occur because the liquid, often mercury or colored alcohol, is sensitive to temperature changes.
What Both animal fats and plant oils are made up of glycerol and?
Both animal fats and plant oils are made up of glycerol and fatty acids. The key difference lies in the types of fatty acids present; animal fats typically contain more saturated fatty acids, while plant oils often have higher levels of unsaturated fatty acids. This composition affects their physical properties and health implications, with animal fats being solid at room temperature and plant oils generally being liquid.
What is increase or decrease for matter to change from one state into another?
An increase in temperature typically causes matter to change from a solid to a liquid or from a liquid to a gas. A decrease in temperature often results in the opposite transition, causing matter to change from a gas to a liquid or from a liquid to a solid.
What is saturated gas temperature?
Saturated gas temperature is the temperature at which a gas would be in equilibrium with the liquid phase of the gas (or with the liquid phase of a component of the gas if it was a gas mixture).
What is the definition of fat?
The major kinds of fats in the foods we eat are saturated, polyunsaturated,monounsaturated and trans fatty acids. Saturated fats, trans fats and dietary fatsFat can also mean someone who is overweight
Difference between fat and oil?
Fat and oils are similar chemically, but the subtle differences that do exist have major effects on health. Fats and oils both consist of molecules that have 'backbones' of long chains of carbon and hydrogen atoms chemically bonded together. These molecules are called 'fatty acids'. Fats and oils in the diet (and most fat in the body) contain three fatty acids chemically bonded to form one fat molecule. A fatty acid may be 'saturated' with hydrogen (ie, all the carbon atoms along the fatty acid backbone have the maximum possible number of hydrogen atoms attached), 'monunsaturated' (two adjacent carbon atoms have less hydrogen atoms) or 'polyunsaturated' (more than two carbon atoms along the fatty acid backbone have less hydrogen atoms) Fats from other animals (eg pork, chicken) are less saturated than ruminant fat and contain some polyunsaturated fatty acids. Fats from game meat (eg, kangaroo, deer) tend to be lower still in saturated fatty acids and often contain significant quantities of a range of polyunsaturated fatty acids. Fats from fish are generally highly unsaturated and contain a form of polyunsaturated fatty acid known as 'omega-3' - Because butter and margarine both contain some water (about 20%), they provide ~30 kJ per gram. Cream contains even more water, so the energy content of 1mL (~ 1gram) of cream is ~14 kJ. Cooking oils and fats generally contain little or no water, so they provide the full 37 kJ per gram. Although all pure fats provide about the same amount of energy, there is some evidence that the effects of fats on weight gain differ according to their chemical composition. It appears that the degree of saturation influences the amount of weight gained or lost on an otherwise similar diet.
Why are large amounts of oxygen often transported as a liquid at low temperature?
The volume is lower and the transport easier.
What characteristics must a liquid have before it can be used in a thermometer?
One thermometric property that is required is that it must vary linearly with temperature. In liquid-in-glass thermometers, the length of the liquid thread is often used to determine temperature. Thus when temperature increases, the liquid must expand uniformly with temperature, so that it can be used to measure temperature accurately.
