Biomolecules Question 72
Question: Long chain molecules of fatty acids are formed by:
Options:
A) polymerisation of 2-carbon compounds
B) decomposition of fats
C) polymerisation of glycogen
D) conversion of glycogen
Show Answer
Answer:
Correct Answer: A
Solution:
Long chain molecules of fatty acids are formed by polymerisation of 2 carbon compounds.
A fatty acid is a carboxylic acid with a long aliphatic tail (chain), which is either saturated or unsaturated.
Most naturally occurring fatty acids have a chain of an even number of carbon atoms, from 4 to 28.
Fatty acids that have carbon-carbon double or triple bonds are known as unsaturated. Fatty acids without double bonds are known as saturated. They differ in length as well.
Long-chain fatty acids (LCFA) are fatty acids with aliphatic tails 13 to 21 carbons.
