Question

The units of structure that build protein and are joined together end to end like pop beads are?

1) Amino acids
2) Nucleotides
3) Monosaccharides
4) Fatty acids

Answer 1

The units that build proteins and join like pop beads are called amino acids. They link via peptide bonds to create polypeptides and finally functional proteins, ordered by the primary structure.

Step-by-step explanation:

The units of structure that build protein and are joined together end to end like pop beads are known as amino acids. Proteins are made from these amino acids, which join together in a chain to form polypeptides, and eventually, functional proteins. Each amino acid has a central carbon (the alpha carbon) bonded to an amino group (NH₂), a carboxyl group (COOH), a hydrogen atom, and a distinctive R group or side chain that varies between the 20 commonly occurring amino acids. When amino acids connect, they form peptide bonds, resulting in a sequence that is known as the primary structure of proteins. As more amino acids join, they can create intricate three-dimensional shapes essential for protein function. Hence, the correct answer to the question is 1) Amino acids.
