He nitrogen cycle is one of the most important (and complex!) of the biogeochemical cycles. Why is nitrogen important?

gayaneshka [121]

Nitrogen is an essential part of proteins and nucleic acids (DNA).

<h3>Why is nitrogen important?</h3>

All living things require nitrogen. It is a part of proteins, ATP, chlorophyll, DNA, and RNA. Given that it makes up a significant portion of the structures of biomolecules in living organisms, its synthesis and consumption in the biogeochemical cycle are of highest importance. Proteins are made up of amino acids (NH2 group).

The structural development of living species' genetic material (DNA, RNA) also involves nitrogen. It is a part of the nitrogenous bases, which together with other nucleotides create RNA and DNA.

Therefore, a nitrogen deficit can cause major structural issues for such an organism.

<h3>What happens if nitrogen cycle is disrupted?</h3>

A number of undesirable consequences can result from the nitrogen cycle being disrupted. For instance, an abundance of nitrogen in aquatic systems leads to eutrophication. Acid rain can be caused by a rise in atmospheric nitrogen.

The majority of ecosystems can tolerate low nitrogen levels since the majority of nitrogen is not biologically accessible in nature. Ecosystems become out of balance when humans significantly increase the quantity of nitrogen that is accessible through fertilizers, fertilizer use, and other means.

What cycloalkanes are present in a steroid ?

11Alexandr11 [23.1K]

Steroids are biologically very important compounds. They are made up of more that seventeen carbons. The structure of Steroid is comprised of a fused cycloalkane ring system. The simplest steroid and the main skeleton of all steroids is Gonane.

Gonane is made up of four cycloalkane rings i.e. tetracyclic hydrocarbon ring structure. Among these four rings 3 are cyclohexanes (designated as A, B and C) and one is cyclopentane (Designated as D). These four rings fuse to form a <span>cyclopentaperhydrophenanthrene.

The Nucleus (Gonane) of steroids along with some derivatives are shown below,</span>
