Guanine

Urea crystals deposited under the skin, which refract and reflect light by creating iridescents.

Guanine is one of the four nucleotides that make up DNA and RNA. The other nucleotides are Adenine, Cytosine and Thymine. Guanine is also one of the four bases that make up nucleotides.

The guanine is a puric base, that is to say that it consists of a puric nucleus with two carbon atoms and five nitrogen atoms. She has a C5H5N5O chemical formula. The guanine is specifically linked to Adenine thanks to a hydrogen-bodied link and this forms an A-G pair base.

In DNA, the guanine is alternating with cytosine and forms a solid basic pair called G-C. In RNA, the guanine is alternating with Uracile and forms a basic pair called G-U.

The guanine is also present in many biological and chemical molecules, including coenzymes, hormones and enzymes. It is also present in many natural drugs and health products.

In aquarophilia, the guanine can be used as a water quality indicator. Indeed, the guanine is produced by bacteria and algae present in water and its concentration can be measured to assess the purity of water. A high concentration of guanine can indicate contamination of water by bacteria or algae and require treatment to ensure the health of fish and other aquatic animals.

In summary, the guanine is an important nucleotide which plays a crucial role in the structure and functioning of DNA and RNA. It is also present in many biological and chemical molecules and can be used as an indicator of water quality in aquarophilia.
