What makes fats oils and waxes?
Fats, oils, and waxes are all made up of molecules called lipids, which are composed of fatty acids and glycerol. The main difference between them lies in their chemical structure and physical properties. Fats are solid at room temperature, oils are liquid at room temperature, and waxes have higher melting points and are more solid than fats.
What is the chemical difference between oils and waxes?
Oils are fats which are liquid at room temperature, waxes are fats which are solid at room temperature. Both waxes and oils can be emulsified. Chemicaly waxes and oils consist of hydrocarbons or esters of fatty acids, they are insoluble in water but soluble in nonpolar organic solvents. The difference in class is based on melting point and larger molecules tend to melt at higer temperatures and are more likely to be waxes, however side chains can lower melting points and hydrogen bonding can raise them. In summary the classification into oil or wax is due to the size of the hydrocarbon and its complexity.
Who has higher iodine number fat or oil?
Oils typically have higher iodine numbers than fats. Iodine number is a measure of the degree of unsaturation in fats and oils, with higher numbers indicating more double bonds and thus greater unsaturation. Oils, which are liquid at room temperature, tend to have more unsaturated fatty acids compared to fats, which are solid at room temperature.
Do all materials melt at the same temperature?
No, different materials have different melting points based on their molecular structure and composition. Some materials have high melting points, such as metals, while others have lower melting points, such as plastics or ice.
What happens to oils when they undergo hydrogenation?
When oils undergo hydrogenation, they become more solid and have a higher melting point. This process changes their chemical structure by adding hydrogen atoms, making them more saturated.
Is this statement true or false saturated fats tend to be solid at room temperature while unsaturated fats tend to be liquid oils at room temperature?
True. Saturated fats have a higher melting point and tend to be solid at room temperature, while unsaturated fats have a lower melting point and are typically liquid oils at room temperature.

Why coconut oil have comparitively higher melting point?
Coconut oil has a higher melting point compared to other oils because it is high in saturated fats, particularly lauric acid. Saturated fats have a more tightly packed molecular structure, which increases the melting point of the oil. This is why coconut oil is solid at room temperature.
Similarities between trans fats and unsaturated fats?
Trans fats are technically unsaturated fats. In cis-fats (healthy) hydrogens are on the same side at the double bond. This gives the molecule a deformed shape that does not pack well. This has an effect of lowering the melting point. In trans-fat the hydrogens are on opposite sides of the double bond. This is more stable and allows tighter packing. Thus trans-fats have higher melting points.H RC::CR HTransR RC::CH HCis
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.

What macromolecules makes up fats oils and waxes in biology?
Lipids.
Does oil have chemicals inside?
Vegetable fats and oils are lipid materials derived from plants. Physically, oils are liquid at room temperature, and fats are solid. Chemically, both fats and oils are composed of triglycerides, as contrasted with waxes which lack glycerin in their structure. Although many different parts of plants may yield oil,[1] in commercial practice, oil is extracted primarily from seeds.The melting temperature distinction between oils and fats is imprecise, since definitions of room temperature vary, and typically natural oils have a melting range instead of a single melting point since natural oils are not chemically homogenous. Although thought of as esters of glycerin and a varying blend of fatty acids, fats and oils also typically contain free fatty acids, mono- and di- glycerides, and unsaponifiable lipids.Vegetable fats and oils may or may not be edible. Examples of inedible vegetable fats and oils include processed linseed oil, tung oil, and castor oil used in lubricants, paints, cosmetics, pharmaceuticals, and other industrial purposes.

What is animal fats and tropical oils?
Animal fats are fats derived from animals, such as lard or tallow, and are commonly used in cooking and food products. Tropical oils are plant-based oils that are extracted from plants grown in tropical regions, like palm oil or coconut oil. Both animal fats and tropical oils are high in saturated fats and can be solid at room temperature.
