What type of fatty acid has 16 carbon atoms including the carboxyl carbon?
Options
- APalmitic acid
- BArachidonic acid
- CGlycerol
- DLecithin
Correct answer
A. Palmitic acid
Step-by-step solution
Lipids are generally water insoluble. They could be simple fatty acids.
A fatty acid has a carboxyl group attached to an R group. The R group could be a methyl (–CH₃), or ethyl (–C2H5) or higher number of –CH₂ groups (1 carbon to 19 carbons). For example, palmitic acid has 16 carbons including carboxyl carbon. Arachidonic acid has 20 carbon atoms including the carboxyl carbon.
