Concept explainers

We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains t…

Protein Expression

The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry…

Students have asked these similar questions

When an inappropriate amino acid is substituted in place of another, as occurs in certain genetic disorders, the resulting protein is either poorly functional or non-functional. Since proteins contain hundreds if not thousands of amino acids, why should the change of a single amino acid be so critical?

With the exception of glycine, all of the standard amino acids have one chiral center. Are there any amino acids that have two chiral centers?

how many different amino acids are there in living organisms?
