Study Notes

Reserved Food Materials: Fixed Oils, Fats, and Waxes

These are stored food materials found in plants and animals.
They are used as antidotes in poisoning cases involving alkaloids or heavy metals.
They can form precipitates with numerous alkaloids.
They act as reagents for detecting proteins, gelatin, and alkaloids through precipitation.
These materials are contraindicated in glaucoma.

Glycosides

Non-reducing substances composed of a sugar part linked to a non-sugar structure called the aglycone or genin.
Steroidal saponins are significant due to their connection to compounds like sex hormones, cortisone, and vitamin D.
Examples: Digitalis and Strophanthus.
Bufadienolide glycosides have an unsaturated 6-membered lactone ring attached to carbon 17.
Example: Squill.
