Guanine

Also known as:  G;  Gua

Guanine is a type of Purine (one of the two major Purines that occurs in all Nucleic Acids).

Nucleic Acids - Polynucleotides

 Guanine is an essential component of Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA):

 Guanine forms part of the Nucleotide portion of the DNA unit.

Nucleic Acids - Bases

 Guanine is a component of Guanosine.

Enzymes

 The Guanine Deaminase enzyme catalyzes the conversion of Guanine into Xanthine and Ammonia in the Liver (i.e. it catalyzes the first step in the endogenous degradation of Guanine).

Herbs

 Guanine is a constituent of Hawthorn.

Yeasts

 Guanine is a constituent of Brewer's Yeast (which contains approximately 254 mg of Thymine per 100 grams).

Free Radicals

 Hydroxyl Free Radicals (if generated near endogenous DNA) may cause mutations of Guanine (they convert Guanine to 8-Hydroxyguanine and other mutated products).
