Question

In all 20 amino acids, a central carbon atom (referred to as the α-carbonα-carbon) bonds covalently to four different atoms or groups of atoms:

Answer 1

Amino acids are the monomers that make up proteins. Each amino acid has a central carbon atom bonded to an amino group (NH₂), a carboxyl group (COOH), and a hydrogen atom. The R group is the only difference in structure between the 20 amino acids.

Step-by-step explanation:

Amino acids are the monomers that make up proteins. Amino acids are the monomers that make up proteins. Each amino acid has a central carbon atom bonded to an amino group (NH₂), a carboxyl group (COOH), and a hydrogen atom. The R group is the only difference in structure between the 20 amino acids.

Each amino acid has the same fundamental structure, which consists of a central carbon atom bonded to an amino group (NH₂), a carboxyl group (COOH), and a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group.

The R group is the only difference in structure between the 20 amino acids; otherwise, the amino acids are identical (Figure 2.20).
