WebIn organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (C(=O)OH) attached to an R-group. The general formula of a carboxylic acid is R−COOH or R−CO 2 H, with R referring to the alkyl, alkenyl, aryl, or other group.Carboxylic acids occur widely. Important examples include the amino acids and fatty acids. Deprotonation …

WebThe C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The convention for …

WebAspartame is an artificial non-saccharide sweetener 200 times sweeter than sucrose and is commonly used as a sugar substitute in foods and beverages. It is a methyl ester of the aspartic acid/phenylalanine dipeptide with the trade names NutraSweet, Equal, and Canderel. First submitted for approval as a food ingredient in 1974, aspartame was …

WebIn organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3.In formulas, the group is often abbreviated as Me.This hydrocarbon group occurs in many organic compounds.It is a very stable group in most molecules. While the methyl group is …

WebIn organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions.The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of …

WebIn chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, UK also / ˈ eɪ m iː n /) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Amines are formally derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called …

WebNomenclature. In IUPAC nomenclature, the prefix benzyl refers to a C 6 H 5 CH 2 substituent, for example benzyl chloride or benzyl benzoate.Benzyl is not to be confused with phenyl with the formula C 6 H 5.The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, (C 6 H 5)(CH 3) 2 …

WebIn organosulfur chemistry, a sulfonyl group can refer either to a functional group found primarily in sulfones, or to a substituent obtained from a sulfonic acid by the removal of the hydroxyl group, similarly to acyl groups.: 1470–1476 Sulfonyl groups can be written as having the general formula R−S(=O) 2 −R′, where there are two double bonds between …

WebThe first researched haptens were aniline and its carboxyl derivatives (o-, m-, and p-aminobenzoic acid).. A well-known example of a hapten is urushiol, which is the toxin found in poison ivy.When absorbed through the skin from a poison ivy plant, urushiol undergoes oxidation in the skin cells to generate the actual hapten, a reactive quinone-type …

WebOrthogonal protection is a strategy allowing the specific deprotection of one protective group in a multiply-protected structure without affecting the others. For example, the amino acid tyrosine could be protected as a benzyl ester on the carboxyl group, a fluorenylmethylenoxy carbamate on the amine group, and a tert-butyl ether on the …
