will i have a triglyceride if i mix 3 parts oil (or butter) in 1 part of glycerol ?
and if i had a little h2so4 ?
Heating aliphatic carboxylic acids with glycerol (and optionally a catalytic amount of a strong mineral acid) will esterify the components to form various triglyceride esters. The procedure is called
Fischer esterification. It will not happen at room temperature (>100°C is suitable) or in aqueous solution.
Neither "oil" or "butter" could be classified as "aliphatic carboxylic acids" though. Stearic acid could, however, and is the main constituent of top-grade old-style candles.
Here is a PPT presentation dealing with the esterification of Glycerol with Stearic Acid, forming Tristearin (a triglyceride ester):

thank you.
You will take me for a fool but i don't understand something,
Do fatty acids that are in oil (corn oil for example) are separated(one by one) OR are they assembled together in complexes (triglycerides) ?
please repond
Both vegetabilic oils and animal fats come as triglyceride molecules:

Free fatty acids are relatively uncommon to find in large amounts in nature:
