The Two Functional Groups Always Found in Amino Acids
Introduction
Amino acids are the building blocks of proteins, essential for various biological processes in living organisms. They are organic compounds that contain two functional groups, which are crucial for their structure and function. In this article, we will explore the two functional groups that are always found in amino acids.
What are Amino Acids?
Amino acids are organic compounds that contain an amino group (-NH2) and a carboxyl group (-COOH) as their two functional groups. There are 20 standard amino acids that are commonly found in proteins, each with a unique side chain that gives them specific properties.
Which Two Functional Groups are Always Found in Amino Acids?
The two functional groups that are always found in amino acids are the amino group (-NH2) and the carboxyl group (-COOH). These two groups are essential for the formation of peptide bonds, which link amino acids together to form proteins.
Table: Sample Data of Amino Acids
| Amino Acid | Amino Group | Carboxyl Group |
|————|————-|—————-|
| Alanine | -NH2 | -COOH |
| Glycine | -NH2 | -COOH |
| Serine | -NH2 | -COOH |
| Phenylalanine | -NH2 | -COOH |
How do Amino Acids Form Peptide Bonds?
When two amino acids come together, the amino group of one amino acid reacts with the carboxyl group of another amino acid, forming a peptide bond. This process continues, creating a chain of amino acids known as a polypeptide. The sequence of amino acids in a polypeptide determines the structure and function of the protein.
Conclusion
In conclusion, the two functional groups that are always found in amino acids are the amino group (-NH2) and the carboxyl group (-COOH). These groups are essential for the formation of proteins and play a crucial role in various biological processes. Understanding the structure and function of amino acids is fundamental in the study of biochemistry and molecular biology.
