How do you dissolve cytosine?
Adenine can be dissolved in water by stirring at 60 0C and remains long after the temperature decreased to RT. Cytosine dissolves in water by stirring at RT.

What are the nucleobases in DNA?
Five nucleobases—adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U)—are called primary or canonical. They function as the fundamental units of the genetic code, with the bases A, G, C, and T being found in DNA while A, G, C, and U are found in RNA.
What do nucleobases do?
a, Nucleobases carry hereditary information through specific hydrogen bonding and steric interactions; that is, adenine with thymine/uracil and guanine with cytosine. Adjacent nucleobases interact with each other via π-stacking, thus forming the double-helix conformation.
Is cytosine soluble in water?
Cytosine, also known as C, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone….Structure for #
| Property | Value | Reference |

What is cytosine soluble?
Free Base: Soluble in water (1 g/130 ml) or 0.1 N HCl (50 mg/ml – clear to very slightly hazy, colorless to faint yellow solution); slightly soluble in ethanol; insoluble in ether.
What is adenine soluble in?
Preparation Instructions. Adenine is soluble in 1 M HCl at 20 mg/mL, obtaining a clear colorless solution. Note: The hydrochloride salt is directly water-soluble.
Is adenosine soluble in water?
Adenosine is the product of the degradation of AMP. For Laboratory Use Only. Not for drug, household or other uses. Soluble in water (7 mg/ml ).
Are nucleobases amino acids?
As shown in Figure 1, alanyl nucleobase amino acids contain a single methylene group connecting the α-carbon atom and nucleobase, more closely analogous to the positioning of (hetero)cyclic functional groups in proteinogenic amino acids such as histidine, tryptophan, phenylalanine and tyrosine.
What are nucleobases made from?
A nucleobase is a nitrogen-containing compound. They may also form nucleosides when they are attached to a five-carbon sugar ribose or deoxyribose. Nucleosides are components of nucleotides. Nucleotide is the monomeric unit of nucleic acid, e.g. DNA and RNA.
What are nucleobases made of?
How are nucleobases formed?
The production of nucleobases by the irradiation of ices with small amounts of pyrimidine and purine under astrophysically relevant conditions supports another family of molecules of astrobiological significance that may form in space and be delivered to the surfaces of newly formed planets.
Is guanine soluble in water?
Guanine is a nucleobase incorporated into biological nucleic acids, such as RNA and DNA. Solubility : Soluble in ammonia-water, KOH solutions, dilute acids, and 1 N NaOH (0.1M). Insoluble in water.
Is cytosine to be soluble or insoluble?
How do you dissolve adenine?
Adenine is soluble in 1 M HCl at 20 mg/mL, obtaining a clear colorless solution. Note: The hydrochloride salt is directly water-soluble. Solutions may be stored at 2–8 °C for months if sterile- filtered.
What is adenosine soluble in?
Solubility : Soluble in 1M NH4OH, water (7 mg/ml), and DMSO (75 mM). Insoluble in ethanol.
What’s the difference between adenine and adenosine?
Adenosine. Although people tend to refer to the nucleotides by the names of their bases, adenine and adenosine aren’t the same things. Adenine is the name of the purine base. Adenosine is the larger nucleotide molecule made up of adenine, ribose or deoxyribose, and one or more phosphate groups.
Are nucleobases aromatic?
The other two nucleobases, adenine and guanine, share the structural backbone of the molecule purine, a six-membered aromatic ring fused to a five-membered aromatic ring with two nitrogen atoms in each ring (Figure 3).
Why is guanine insoluble in water?
Its high melting point of 350 °C reflects the intermolecular hydrogen bonding between the oxo and amino groups in the molecules in the crystal. Because of this intermolecular bonding, guanine is relatively insoluble in water, but it is soluble in dilute acids and bases.
