Sum by chain length

• Short chain fatty acids (SCFAs) are fatty acids with aliphatic tails of 5 or fewer carbons (e.g. butyric acid).[7]
• Medium chain fatty acids (MCFAs) are fatty acids with aliphatic tails of 6 to 12 carbons, which can form medium-chain triglycerides.[8]
• Long chain fatty acids (LCFAs) are fatty acids with aliphatic tails of 13 to 21 carbons.[9]
• Very long chain fatty acids (VLCFAs) are fatty acids with aliphatic tails of 22 or more carbons.
