The fatty acids have carboxylic group 'COOH' at terminal this is a group having 'OH' group attached to carbonyl carbon but it is not alcohol.
carboxyl group
Saturated fatty acid molecules have no carbon-carbon double bonds, and all of the remaining carbon bonds are shared by hydrogen atoms, except the one in the carboxyl group, at the beginning of the chain.Unsaturated fatty acid molecules also begin with the carboxyl group, but contain one or more carbon-carbon double bonds, and may contain one or more carbon atoms with a bonding electron that remains unassociated.
Most lipids are composed of some sort of fatty acid arrangement. The fatty acids are Fatty acids are composed of a chain of methylene groups with a Carboxyl functional group at one end.
Carboxyl group
Like many organic compounds, the names of fatty acids such as omega-6 and omega-3 contain numbers that are used to describe the position of certain features of the molecule. In the case of omega fatty acids, the numbers 3 and 6 tell where the final carbon-carbon double bond is located. The numbers tell how many carbon-carbon bonds away from the carboxyl group this bond is. Omega-6 fatty acids are generally regarded as unhealthy when eaten in larger quantities than omega-3 fatty acids because they interfere with the omega-3's functions in the body.
Fatty acids contain carboxyl groups. The functional group of fatty acids is -COOH. There are 2 types of fatty acids called saturated and non saturated.
carboxyl group
Fatty acids contain C, H, O.
No, only fatty acids contain carboxyl groups.
No - neither of them do.
Well cholesterol itself is only 1 molecule, it can't *really* contain any other molecules. It does, however have some structural similarities with fatty acids such as the nice long hydrophobic tail. It has an OH group also, so it's possible that it shares some metabolic routes and functions with fatty acids or is derived from them (we can reduce a carboxylic acid - found in fatty acids - to an alcohol group - OH). We probably need a molecular biologist to confirm that, though :).
carboxylic
No, only fatty acids do contain a carboxyl group -C(=O)(-OH) (they are alternatively called: carboxylic acids). Glycerol contains three hydroxylic groups -C(-OH), propane-1,2,3-triol
Phospholipid molecule is actually almost similar to a lipid molecule. It is a alcohol connected to 2 fatty acids and a phosphate group.(In lipids, its connected to 3 fatty acids)
no amino acid is not a fatty acid this is because of the following reasons 1- due to the difference of functional group i.e Amino acid has two functional groups one is amino group (-NH2) and other is carboxylic group (-COOH) while in fatty acid (-RCOOH) only carboxylic group are present. 2-Amino acid is the sub-unit of protein while Fatty acid is the sub-unit of lipids(FATS).
2 fatty acids, glycerol, and a phosphate group
Fatty acids and monosaccharides belong to the biomolecule group Proteins and Amino Acids.
