Fats are composed of three fatty acid molecules joined to a molecule of?
glycerol
How do fatty acid hydrocarbon chains interact with each other within a plasma membrane or lipid bylayer?
Fatty acids don't actually interact with each other. A better way to describe it is that they clump together by a "hydropobic exclusion". Interactions between hydropbobic and hydrophylic molecules are energetically unfavourable means that the fatty acid chains isolate themselves from the polar solution around them. Similarly interactions between the polar parts of the bilayer and the polar solution around them is energetically favourable. In summary; fatty acid chains DO NOT interact with eachother. The polar solution EXCLUDES them from the outside of the bilayer.
Is a sodium fatty acid salt the same as a carboxylic acid salt?
A fatty acid salt is a kind of carboxylic acid salt. But not all carboxylic acid salts are fatty acid salts.
What are chains of carbon and hydrogen with a carboxyl at one end?
Such compounds are Fatty acids (long chain monocarboxylic acids)
What fatty acid is present in detergent?
i dont think its a fatty acid
Which part of the membrane prevents organisms from dissolving in water?
Nonpolar fatty acid chains.Non fatty acid chains
What part of the cell membrane prevents the cell from dissolving in water?
Nonpolar Fatty acid chains
What macromolecules make up the cell membrane?
The cell membrane is composed of a bilayer of phospholipids, which are composed of a glycerol molecule chemically combined with a polar hydrophilic phosphate head and two hydrophobic fatty acid tails.
What part of the cell membrane prevents organisms from dissolving organisms from dissolving in water?
The lipid bilayer prevents the cell from dissolving in water.
Hydrophobic reactions of phospholipids may produce clusters of their fatty acid tails which form what?
lipid bilayer
What is a double layer of phospholipids?
A cell's membrane (plasma membrane) is made of a phospholipid bilayer where the hydrophillic phosphate groups form the two outer sides of the bilayer and the hydrophobic fatty acid chains are the interior.
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
a lipid bilayer
Is Triglyceride a lipid?
Yes triglycerides are lipids. Triglycerides are composed of fatty acids and glycerol. Lipids are composed of fatty acid molecules, phospholipids, monoglycerides, and metabolites.
How does phopholipds behave in water?
When placed in water, phospholipids will orient themselves into a bilayer in which the non-polar tail region faces the inner area of the bilayer.
Fats are composed of three fatty acid molecules joined to a molecule of?
glycerol
What are triglycerides and what kind of fatty acid is this?
Triglycerides are a type of fatty acid that aid in the bodily processes of the liver. They are composed of one glycerol and three fatty acids, hence the name, tri-glycerides.
What part of the cell membrane make up the phospholipid bilayer?
Phosholipids are composed of a glycerol backbone, 2 fatty acids, and a phosphate group. Two fatty acid chains are attached to the first 2 carbon molecules of the glycerol chain. The 3rd carbon of the glycerol backbone is attached to a phosphate group.
