Products Bisphosphonates are commercially available in the form of film-coated tablets and as injection and infusion preparations. They are also combined fixed with vitamin D3. Their effects on bone were described in the 1960s. Etidronate was the first active ingredient to be approved (out of trade). Structure and properties Bisphosphonates contain a central carbon atom … Bisphosphonates Effects and Side Effects
Definition Aldehydes are organic compounds with the general structure R-CHO, where R can be aliphatic and aromatic. The functional group consists of a carbonyl group (C=O) with a hydrogen atom attached to its carbon atom. In formaldehyde, R is a hydrogen atom (HCHO). Aldehydes can be obtained, for example, by oxidation of alcohols or by … Aldehydes
Definition Ketones are organic compounds containing a carbonyl group (C=O) with two aliphatic or aromatic radicals (R1, R2) attached to its carbon atom. In aldehydes, one of the radicals is a hydrogen atom (H). Ketones can be synthesized, for example, by oxidation of alkoles. The simplest representative is acetone. Nomenclature Ketones are usually named with … Ketones
Definition Amides are organic compounds containing a carbonyl group (C=O) whose carbon atom is bonded to a nitrogen atom. They have the following general structure: R1, R2 and R3 can be aliphatic and aromatic radicals or hydrogen atoms. Amides can be synthesized with a carboxylic acid (or a carboxylic acid halide) and an amine using … Amide
Products Carbon dioxide is commercially available in compressed gas cylinders liquefied and as dry ice, among other products. The various products differ in purity. Carbon dioxide is also monographed in the pharmacopoeia. It is available, for example, in grocery stores for making your own sparkling water. Structure Carbon dioxide (CO 2 , O=C=O, M r … Carbon Dioxide
Products Rasagiline is commercially available in tablet form (Azilect). It has been approved in many countries since 2005. Generic versions were first released in 2015. Structure and properties Rasagiline (C12H13N, Mr = 171.24 g/mol) is an aminoindan derivative and has an asymmetric carbon atom. Therapeutic uses are found for the -enantiomer. It is present in … Rasagiline
Definition Alcohols are a group of organic compounds with the general chemical structure R-OH. The hydroxyl group (OH) is attached to an aliphatic carbon atom. Aromatic alcohols are called phenols. They are a separate group of substances. Alcohols can be obtained as derivatives of water (H 2 O) in which a hydrogen atom has been … Alcohols
Definition and structure Fatty acids are lipids consisting of a carboxy group and a hydrocarbon chain that is usually unbranched and may contain double bonds. The figure shows palmitic acid with 16 carbon atoms (C16): they typically exist in nature free or in the form of glycerides. Glycerides consist of a molecule of glycerol esterified … Fatty Acids
