“氨基”和“胺基”的区别是什么？ - 百度知道
氨基（Amino）是有机化学中的基本碱基，所有含有氨基的有机物都有一定碱的特性，由一个氮原子和两个氢原子组成，化学式-NH2。 如氨基酸就含有氨基，有一定碱的特性。
胺 - 维基百科，自由的百科全书
胺 àn 类 （英語： amine）简称 胺，是 氨 分子中的一个或多个 氢 原子被 烃基 取代 后形成的一类 有机化合物。 胺基 （－NH 2 、－NHR、－NR 2）是胺的 官能团。 如果氮原子连着 羰基 （C=O），那么该化合物则称为 醯胺，其化学性质与胺并不相同。 在中国大陆（即便繁体），“胺”（读作：àn/ㄢˋ）字仅用作 化学名 後綴，即当氨基（－NR 2）是化合物“主要官能团”时，称为某某胺，如： 亚硝胺 等；当氨基（－NR 2）作为“次要官能团”时，则此官能团名称改用“氨”（读 …
Amine - Wikipedia
In chemistry, amines (/ əˈmiːn, ˈæmiːn /, [1][2] UK also / ˈeɪmiːn / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.
2.2: Structure & Function - Amino Acids - Biology LibreTexts
2024年3月21日 · Each amino acid has at least one ionizable amine group (α- amine) and one ionizable carboxyl group (α- carboxyl). When these are bound in a peptide bond, they no longer ionize. Some, but not all amino acids have R-groups that can ionize.
5.1: Amines - Structures and Names - Chemistry LibreTexts
2 天之前 · Thus, although isopropylamine looks similar to isopropyl alcohol, the former is a primary amine, while the latter is a secondary alcohol. The common names for simple aliphatic amines consist of an alphabetic list of alkyl groups attached to the nitrogen atom, followed by the suffix -amine. (Systematic names are often used by some chemists.)
20.4: Amines and Amides - Chemistry LibreTexts
Amines are molecules that contain carbon-nitrogen bonds. The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix –ine as illustrated here for a few simple examples:
Amine | Organic Chemistry, Structure & Uses | Britannica
2024年11月22日 · amine, any member of a family of nitrogen-containing organic compounds that is derived, either in principle or in practice, from ammonia (NH 3).. Naturally occurring amines include the alkaloids, which are present in certain plants; the catecholamine neurotransmitters (i.e., dopamine, epinephrine, and norepinephrine); and a local chemical mediator, histamine, that occurs in most animal tissues.
26.1 Amines – Structure and Naming – Organic and Biochemistry ...
Identify the general structure for an amine. Identify the functional group for amines. Determine the structural feature that classifies amines as primary, secondary, or tertiary. Use nomenclature systems to name amines. Amines are molecules that contain carbon-nitrogen bonds.
1.11: Amines and Amides - Chemistry LibreTexts
Amines and amides are two compounds which contain amino or substituted amino groups. Amines are designated as primary, secondary, or tertiary amines based upon the degree of substitution of the amino group. For example, an amine in which all three of the potential nitrogen bonds are with R groups instead of hydrogens is called a tertiary amine ...
