Rule nine – Hide your crumpled cheat sheets! How to remember the formulas of anthraquinone derivatives? The formulas of anthraquinone derivatives usually do not seem complicated enough for students. The main thing to remember is that at the core of their structure, all of them contain 3 conjugated benzene rings. Anthracene…
Rule eight: we do not ask for leniency. How to remember the formulas of xanthones? We have just completed the study of lignan formulas by examining the structure of flavolignans and, in particular, flavonoids that are part of their composition. At the moment, the knowledge we have gained will be useful. If flavonoids have…
Rule number seven – it is fraught to agree with everything. How to remember the formulas of lignans? At the beginning of studying the formulas of lignans, you need to clearly imagine where their “head” is and where the “tail” is. Look at them closely: the “head” is the benzene ring (it even…
Rule six – it is not worth boasting about victories! How to remember the formulas of simple phenols and their derivatives? You should already know the formulas of basic phenolic compounds from your organic chemistry course. Let’s recall! Phenol is a benzene ring with one –OH group. If there are two –OH groups…
Rule five – the rich get richer. (this also applies to knowledge) How to memorize the formulas and names of cardioglycosides? Cardanolides and bufadienolides are also one of the complex topics in the pharmacognosy course. Therefore, in this case, in addition to our advice, you also need to use your own…
Rule number three: do not look at whom you fear! How to remember the formulas of essential oil components? The material we are approaching is very significant in terms of information volume. I recommend assimilating it in parts – as we will consider them. Focus all your attention and let’s begin. …
The second rule – the reward awaits the hero. How to remember the formulas of iridoids?

This bond in all iridoids is located…
Rule number one:a taste for growth is essential! How to remember the formulas of lipids and fatty acids? From the course of organic chemistry, you should remember that fats are complex esters of the trihydric alcohol glycerol and high molecular weight carboxylic acids, which are also called fatty acids. Therefore, your only…
Rule Zero: Let your brain be the hero.(Wisdom from the vintage “Advisor” computer program) How to remember the formulas of polysaccharides?
