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 ...
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 ...
Alkaloids are among the most important and best-known secondary metabolites, i.e. biogenic substances not directly involved in the normal growth, development, or reproduction of the organism. Instead, they generally mediate ecological interactions , which may produce a selective advantage for the organism by increasing its survivability or ...
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
Jennifer Lopez opened up in a new interview with British Vogue, discussing how she approaches “hardships” in the wake of her divorce from Ben Affleck.
More specifically, the lipophilic base structure of a saponin can be a triterpene, a steroid (such as spirostanol or furostanol) or a steroidal alkaloid (in which nitrogen atoms replace one or more carbon atoms). Alternatively, the base structure may be an acyclic carbon chain rather than the ring structure typical of steroids.
The Year Without a Santa Claus, a Christmas special from Jules Bass and Arthur Rankin, Jr., turns 50 this December. The beloved special was adapted from the book of the same name by Phyllis ...
