In nature, fatty acid double bonds (i.e., unsaturations) almost always have the cis configuration. This kind of molecular architecture puts a rigid 30º bend in the hydrocarbon chain of unsaturated fatty acids that interferes with their efficient packing to fill space. The consequence of this configuration is a reduction of van der Waals interactions causing fatty acids melting points to decrease with their degree of unsaturation. With this configuration, lipid fluidity likewise increases with the degree of unsaturation of their component fatty acid residues. This property of fatty acids has primary importance in membrane fluidity and in ion and molecule trafficking through it.

Which type of fatty acid has hydrogen atoms located on the same side of the double bond?
A cis fatty acid has hydrogen atoms located on the same side of the double bond. This configuration creates a bend or kink in the hydrocarbon chain, affecting the physical properties of the fatty acid.
Do trans or cis fatty acids have a higher melting point?
The trans fatty acid has a higher melting point. The trans isomer is straighter in shape and this allows the molecules to be packed closer together. The molecules are hence held together by greater Van der Waal's force.
Is cis-trans confirmation or configuration?
"Cis-trans" is a term used in chemistry to describe the spatial arrangement of atoms or groups around a double bond. It refers to the relative positions of substituents on either side of the double bond. Configuration, on the other hand, is a broader term that encompasses both cis-trans and other spatial arrangements of atoms in a molecule.
What is the difference between cis- and trans-fatty acids?
Just the difference between cis and trans isomers. The arrangement of functional groups around double bonded carbons. Same groups lined up on the same side are cis fatties and alternate groups lined up on the different sides are trans fatty acids.
How is stearidonic acid different from stearic acid?
Stearidonic acid is multi UNsaturated: (all cis)6,9,12,15-octadeca-tetra-en-oic acid, C18H28O2Stearic acid is fully saturated: octadec-an-oic acid, C18H36O2

Why are cis fatty acids rearranged to trans fatty acids in the process of partial hydrogenation?
During partial hydrogenation, cis fatty acids are rearranged to trans fatty acids because of the difference in the spatial orientation of hydrogen atoms on the carbon chain. The catalyst used in the process favors the alignment of hydrogen atoms on opposite sides of the carbon chain, leading to the formation of trans double bonds. This process changes the structure of the fatty acids from a cis to a trans configuration.
What is cis fat?
The basic building block of "fat" are fatty acids. Cis is a term used in chemistry and other sciences. Below is the definition of cis from Answers.com cis-pref. # On this side: cisatlantic. # Having a pair of identical atoms or groups on the same side of a plane that passes through two carbon atoms linked by a double bond. Used of a geometric isomer: cis-2-butene. [Latin, from cis, on this side of.] In an effort to answer "Cis Fat", the description below is cut and pasted from Answers.com for "Unsaturated fatty acid" Hopefully this helps:-) unsaturated fatty acid A http://www.answers.com/topic/fatty-acid that contains one (monounsaturated) or more (polyunsaturated) double bonds between carbon atoms. Each double bond takes the place of one hydrogen atom. In cis fatty acids, the two hydrogen atoms adjacent to a double bond are on the same side. This imposes a kink in the molecule making cis unsaturated fatty acids less easy to pack together. Consequently, cis unsaturated fats are usually liquid (oil) at room temperature. In trans-unsaturated fatty acids, the two hydrogen atoms adjacent to a double bond are on opposite sides, enabling the atoms to pack more closely together and giving the trans unsaturated fatty acids physical properties similar to saturated fatty acids. Eating large amounts of foods with high levels of trans unsaturated fatty acids is generally regarded as more detrimental to health than eating comparable amounts of food containing cis unsaturated fatty acids.
What is structure of z-2-chlorobutenedioic acid?
The structure of Z-2-chlorobutenedioic acid, also known as cis-2-chlorobuten-1,2-dioic acid, has a cis configuration with a chlorine substituent on the second carbon of the butenedioic acid chain. This compound is a dicarboxylic acid with a carboxylic acid group on each end of the chain.

Is olive oil an essential fatty acid?
No, it's not a fatty acid or essential fatty acid.
What is the difference between cis- and trans-fatty acids?

What are the factors that influence whether a fatty acid is liquid or solid?
The factors that influence whether a fatty acid is liquid or solid include the length of the fatty acid chain (longer chains are more likely to be solid), the degree of saturation (saturated fats are more likely to be solid), and the presence of cis or trans double bonds (trans fats tend to be solid at room temperature).
What are the key differences between cis and trans biology?
Cis and trans biology refer to the arrangement of molecules in a compound. In cis configuration, the functional groups are on the same side of the molecule, while in trans configuration, they are on opposite sides. This difference can affect the properties and functions of the compound.
