Nucleic Acids

Structure and properties Nucleic acids are biomolecules found in all living things on Earth. A distinction is made between ribonucleic acid (RNA, RNA, ribonucleic acid) and deoxyribonucleic acid (DNA, DNA, deoxyribonucleic acid). Nucleic acids are polymers composed of so-called nucleotides. Each nucleotide consists of the following three units: Sugar (carbohydrate, monosaccharide, pentose): ribose in RNA, … Nucleic Acids

Acetic Anhydride

Products Acetic anhydride is available in specialized stores. Structure and properties Acetic anhydride (C4H6O3, Mr = 102.09 g/mol) is the condensation product of two acetic acid molecules. It exists as a colorless liquid with a pungent odor of acetic acid. This is a result of hydrolysis with water: C4H6O3 (acetic anhydride) + H2O (water) 2 … Acetic Anhydride

Ester

Definition Esters are organic compounds formed by the reaction of an alcohol or phenol and an acid such as a carboxylic acid. The condensation reaction releases a water molecule. The general formula of esters is: esters can also be formed with thiols (thioesters), with other organic acids, and with inorganic acids such as phosphoric acid … Ester

Auxiliary Materials

Definition On the one hand, drugs contain the active ingredients that mediate the pharmacological effects. On the other hand, they consist of excipients, which are used for the production or to support and regulate the drug effect. Placebos, which consist only of excipients and contain no active ingredients, are an exception. Excipients can be of … Auxiliary Materials
