Chemistry Thursday: Carboxylic acids – long chain fatty acids (C14 to C16) – figuring out their molecular formulas, melting points, and omega-3, 6, 9 – part 23

by

Welcome back to this beginners’ 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 met...

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

by

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...

Chemistry: Alkanes (double bonds), saturation, and types of bonds (part 19)

by

Welcome to part nineteen of this series on learning chemistry! In part one, we looked at the resources and materials we need to study chemistry. In part two, we learned the parts of an atom – protons, neutrons, and electrons! In part three, we learned about ions and valence shells. In part four, we learned...
