Arrange these structures of fatty acid in descending order based on their melting point and give a reason.the structures are palmitic acid palmitoleic acid linoleic acid myristic acid and stearic acid?
The structures in descending order based on melting point are: stearic acid > palmitic acid > myristic acid > palmitoleic acid > linoleic acid. This is because longer fatty acids with saturated bonds have higher melting points compared to shorter fatty acids or those with unsaturated bonds.
Why does stearic acid melt at 69 but linoleic acid melts at9?
Linoleic acid is an unsaturated fatty acid. This means less energy is required to separate the molecules due to its irregular/bent shape. The bends come from the cis double bonds in the carbon chain.
What is the formula for conjugated linoleic acid?
The formula for conjugated linoleic acid is C18H32O2. Conjugated linoleic acids are a family of at least 28 isomers of linoleic acid. Conjugated linoleic acid (CLA) is a mixture of positional and geometrical isomers of linoleic acid.
How do you prove that glucose do not raise the melting point of stearic acid?
To prove that glucose does not raise the melting point of stearic acid, conduct a melting point analysis of stearic acid alone and stearic acid mixed with glucose. If the melting point of the mixture is the same as that of stearic acid alone, it indicates that the presence of glucose does not affect the melting point of stearic acid. This experiment can help demonstrate that glucose does not raise the melting point of stearic acid.
What is the melting point of ethanoic acid?
The melting point of ethanoic acid, also known as acetic acid, is 16.6 degrees Celsius.

Which factor determines how much linoleic acid and can twist and bend its shape?
The level of unsaturation in a fatty acid determines how much linoleic acid can twist and bend its shape. Linoleic acid is a polyunsaturated fatty acid with two double bonds, which introduces kinks in its carbon chain, preventing tight packing and allowing flexibility. The presence of these double bonds affects its physical properties, such as melting point and fluidity, making it more versatile in biological systems.
Why does stearic acid melt at 69 C but linoleic acid melts at 5C?
Stearic acid melts at 69°C due to its long, saturated hydrocarbon chain, which allows for strong van der Waals forces between molecules, requiring more energy (heat) to break these interactions. In contrast, linoleic acid has a shorter chain and contains two double bonds, creating kinks that disrupt the packing of molecules and reduce intermolecular forces. This results in a lower melting point of 5°C for linoleic acid. Thus, the presence of saturation and chain length significantly influences their melting points.
What is acetic acid melting point?
The acetic acid melting point is approx. 17 oC.
Which of the following lipids is an essential nutrient?
Linoleic acid

Which fatty acid is converted to arachidonic acid which serves as the precursor to the localized hormones known as eicosanoids?
Arachidonic acid is a 20:4(delta5,8,11,14) derivative fatty acid from linoleic acid. Linoleic and linolenic acids are "essential fatty acids" for mammals and they must be consumed from plant sources. Once consumed, linoleic acid may be converted to other polyunsaturated acids, particularly gamma-linoleic acid, eicosatrienoate and arachidonic acid (or eicosatetranoate) which can be only from linoleic acid.
What is the melting point of 3-formyl salicylic acid?
Melting point of 3-formyl salicylic acid is 132 degrees Celsius.
What is gamma-linoleic acid?
Gamma-linoleic acid (GLA) is an omega-6 polyunsaturated fatty acid made in the body from linolenic acid, an essential fatty acid (EFA).
