역사

Guanine is one of the two purines comprising the five nucleic acid bases. Much of the information regarding the general role of nucleic acid bases is covered in Adenine and Cytosine. Guanine gets its name from guano, from which it was first isolated in the 1840s. Albrecht Kossel (1853 1927) determined that guanine (as well as adenine, cytosine, thymine and uracil) was a component of nucleic acid in the last two decades of the 19th century. Similar to adenine, guanine combines with ribose to form a nucleoside. The nucleoside produced is guanosine, which in turn combines with one to three phosphoryls to yield the nucleotides guanosine monophosphate (GMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP), respectively. Guanine nucleotides play an important role in metabolism including the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) and carbohydrate metabolism.

용도

Guanine is a crystalline amorphous substance that is found in guano, fish scales, and theliver of certain mammals. Guanine is responsible for the silvery iridescence of certain fishscales. Before its discovery, guanine was scraped from fish scales and used to coat beads to produceimitation pearls. Thus it was called pearl essence or pearly white in the 1700s. Guanineobtained from fish scales is used in cosmetics, especially for eye cosmetics and nail polishes.

용도

Guanine is on one of the five nucleobases incorporated into biological nucleic acids. Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA.

용도

guanine is mixed in water and used primarily in nail polish to achieve a pearlized effect. It has been greatly replaced by either synthetic pearl or aluminum and bronze particles. guanine is obtained from plant or animal sources.

정의

A nitrogenous base found in DNA and RNA. Guanine has a purine ring structure.

정의

guanine: A purine derivative. It isone of the major component bases ofnucleotides and the nucleic acidsDNA and RNA.

정의

ChEBI: A 2-aminopurine carrying a 6-oxo substituent.
