Amino Functional Group - ChemTalk
The amino group is an important functional group for many biological systems. Below we discuss the structure of an amino group, some quick stats on the functional group, reactions with amino groups, and the amino functional group role in peptide bonds.

2021年9月17日 · All amino acids have the same basic structure, which is shown in Figure 2.1. At the “center” of each amino acid is a carbon called the α carbon and attached to it are four groups - a hydrogen, an α- carboxyl group, an α-amine group, and an R-group, sometimes referred to as a side chain.

2024年3月21日 · All amino acids have the same basic structure, which is shown in Figure 2.1. At the “center” of each amino acid is a carbon called the α carbon and attached to it are four groups - a hydrogen, an α- carboxyl group, an α-amine group, …
1.9: Functional Groups - Biology LibreTexts
Some of the important functional groups in biological molecules are shown above; they include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl (R-S-H). These groups play an important role in the formation of molecules …
Amino Acids - Benefits, Structure & Function - Biology Dictionary
2020年10月27日 · Amino acids are the building blocks of polypeptides and proteins and play important roles in metabolic pathway, gene expression, and cell signal transduction regulation. A single organic amino acid molecule contains two functional groups – amine and carboxyl – and a unique side chain.
4.3: Amino Acids - Biology LibreTexts
Each variable group on an amino acid gives that amino acid specific chemical properties (acidic, basic, polar, or nonpolar). You should be familiar with most of the functional groups in the R groups by now.
26.1: Structure and Properties of Amino Acids
The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain pH value (different for each amino acid) nearly all the amino acid molecules exist as zwitterions.
26.1 Structures of Amino Acids - Organic Chemistry - OpenStax
The structures, abbreviations (both three- and one-letter), and p Ka values of the 20 amino acids commonly found in proteins are shown in Table 26.1. All are α-amino acids, meaning that the amino group in each is a substituent on the α carbon—the one next to the carbonyl group.
2.2: Structure and Function – Amino Acids
At the center of each amino acid is a carbon called the α carbon and attached to it are four groups – a hydrogen, a carboxylic acid group, an amine group, and an R-group, sometimes referred to as a variable group or side chain.
Amino Acids: Structure, Groups and Function - ThoughtCo
2024年9月3日 · All amino acids have the alpha carbon bonded to a hydrogen atom, carboxyl group, and amino group. The "R" group varies among amino acids and determines the differences between these protein monomers.
