Chemistry: Carboxylic acids – long chain fatty acids (stearic acid, C18:0) and a bit on triglycerides, part 24

by
Stearic acid in a tin plate, which is a white flaky solid.

Welcome back to this introduction to chemistry series! I hope you’re enjoying it so far. I know I am! Let’s talk more about carboxylic acids, specifically the fatty acids we encounter over and over again in our liquid oils, solid oils, butters, and waxes. In part 21 of this series – carboxylic acids – we...

Chemistry Thursday: Carboxylic acids – medium chain fatty acids (part 22) 

by
A jar of coconut oil sits on a table with a green leaf tablecloth. A dollop of white creamy coconut oil sits on a spoon atop the jar.

In today’s post, part 22, we’re meeting medium chain fatty acids – caproic acid, caprylic acid, capric acid, and lauric acid – all of which we encounter regularly in cosmetic chemistry. An important note about this series – it’s here for life. It isn’t going anywhere. If you want to take a break or take...

Chemistry: Carboxylic acids – short chain acids (part 21)

by

Welcome to part 21 of this series on learning chemistry! At this point of the series, we’ve met a number of molecules – alkanes (single bond), alkenes (double bond), alkynes (triple bond), and alcohols (have at least one OH group). Today, let’s meet carboxylic acids – small and medium chain ones – that have an...
