Polycyclic organic compound having sterane as a core structure This article is about the family of polycyclic compounds. For the drugs, also used as performance-enhancing substances, see Anabolic steroid. For the scientific journal, see Steroids (journal). For the Death Grips EP, see ...
Sterols are steroids in which one of the hydrogen atoms is substituted with a hydroxyl group, at position 3 in the carbon chain. They have in common with steroids the same fused four-ring core structure. Steroids have different biological roles as hormones and signaling molecules.

The left-most structure is a bond-line drawing where the hydrogen atoms are removed. The 2nd structure has the hydrogens added depicted-the dark wedged bonds indicate the hydrogen atoms are coming toward the reader, the hashed bonds indicate the atoms are oriented away from the reader, and the solid (plain) bonds indicate the bonds are in the ...
The B-ring of the parent steroid is broken between C9 and C10 to yield D vitamins. A secosteroid (/ ˈ s ɛ k oʊ ˌ s t ɛ r ɔɪ d /) is a type of steroid with a "broken" ring. The word secosteroid derives from the Latin verb secare meaning "to cut", [2]: 241 and 'steroid'. Secosteroids are described as a subclass of steroids under the IUPAC ...
Examples of disaccharides include sucrose, maltose, and lactose. Polysaccharides are polymerized monosaccharides, or complex carbohydrates. They have multiple simple sugars. Examples are starch, cellulose, and glycogen. They are generally large and often have a complex branched connectivity.
The concept of replacing hydrogen with deuterium is an example of bioisosterism, whereby similar biological effects to a known drug are produced in an analog designed to confer superior properties. [5] The first patent in the US granted for deuterated molecules was in the 1970s. Since then patents on deuterated drugs have become more common. [6]
For example, a single polymeric molecule is appropriately described as a "macromolecule" or "polymer molecule" rather than a "polymer," which suggests a substance composed of macromolecules. [ 8 ] Because of their size, macromolecules are not conveniently described in terms of stoichiometry alone.
