an amino group and a carboxylic acid group
Functional groups are specific groups of atoms within a molecule that are responsible for the characteristic chemical reactions of that molecule. Common functional groups include hydroxyl (-OH), carbonyl (C=O), carboxyl (-COOH), amino (-NH2), and phosphate (-PO4). These groups give molecules unique properties and determine their reactivity with other molecules.

Functional groups in an IR spectrum can be identified by looking for specific peaks or bands that correspond to characteristic vibrations of different functional groups. Each functional group has unique vibrational frequencies that can be matched to peaks in the spectrum, allowing for their identification.
Amino acids are called amino acids because they contain an amino group (-NH2) and a carboxyl group (-COOH) in their chemical structure. These two functional groups are essential for the formation of proteins and are characteristic of all amino acids.
The characteristic IR spectrum stretches of the functional group present in the compound can be identified by analyzing the peaks in the infrared spectrum. Each functional group has specific peaks that correspond to the vibrations of the bonds within that group. By comparing the peaks in the spectrum to known values for different functional groups, the presence of a particular functional group can be determined.

Amino acids have 2 functional groups, an a-carboxyl group and an-amino group.

Proteins are made up of amino acids, which are made up of amines (NH2) and carboxyls (COOH). They are joined by peptide bonds. Examples of functional categories of proteins includes Contractile proteins, regulatory proteins, structural proteins, transport proteins, catalytic proteins and immunological proteins

Monomers are small, simple molecules that can bond together to form larger, more complex molecules. They typically have reactive functional groups that enable them to undergo polymerization reactions. Monomers are the building blocks of polymers and can be identical or different in a polymer chain.
The monomers of natural polymers, such as proteins and polysaccharides, are typically larger and more complex in structure compared to the simpler monomers used to make synthetic plastics. For instance, amino acids, which are the building blocks of proteins, possess intricate structures with various functional groups, while polysaccharides like cellulose are composed of repeating sugar units. In contrast, the monomers for plastics, like ethylene and propylene, are generally small and simple hydrocarbons. This complexity in natural polymers often contributes to their diverse biological functions and properties.
Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. They determine the properties and reactivity of organic compounds, influencing factors such as polarity, acidity, and solubility. Common examples of functional groups include hydroxyl (-OH), carboxyl (-COOH), and amino (-NH2) groups. Understanding functional groups is essential for predicting the behavior of organic molecules in chemical reactions.
Regardless of the countless arrangements of the tewnty plus amino acids, all proteins contain the amine group (-NH2) and the carboxylic group (-COOH). These groups or monomers appear in every amino acid.
Long chains of bonded groups refer to polymers, which are large molecules made up of repeating structural units called monomers. These monomers are connected through covalent bonds, forming lengthy, continuous chains. Polymers can be natural, like proteins and nucleic acids, or synthetic, like plastics and nylon, and their properties depend on the types of monomers used and the arrangement of these chains.
Amino acids are called amino acids because they contain an amino group (-NH2) and a carboxyl group (-COOH) in their chemical structure. These two functional groups are essential for the formation of proteins and are characteristic of all amino acids.
