Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Proteins are composed of what smaller building blocks?
A
amino acids
B
nucleic acids
C
fatty acids
D
nucleotides
Explanation: 

Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-2: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-3: -A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.

Detailed explanation-4: -The correct answer is (E): Amino acids, which can form new protein. The building blocks of proteins and peptides are molecules called amino acids.
