A steroid is a type of lipid that has four rings of carbon atoms.
Three properties all steroid molecules have in common are:
1) They are insoluble in water
2) They are all organic compounds
3) They all have three 6-sided carbon rings and one 5-sided carbon ring.
Hope this helps! :)
Always contain Carbon
The majority of organic compounds contain carbon, hydrogen, and occasionally other elements such as nitrogen, sulfur, oxygen, or phosphorus.
<h3>What are Organic compounds ?</h3>
Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
- The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
- Carbon is the key element because it has four electrons in an outer electron shell that can hold eight electrons
