not as such, because proteins are so big they can't get into cells
from the outside. They have to be made inside the cells. Now you
know why it won't work to take proteins in a pill or powder form
like other medicines.
What about proteins
that you eat? Meat has lots of proteins. What happens to
meat that you eat?
- It gets digested, of course.
- And what does
digestion mean? .... broken down (to amino acids). So any proteins you
eat get broken down.
- Then the pieces get taken into your cells
and are used as building blocks to make new protein
If you know why proteins
are medically important, what they do, and how they are made
by instructions from the genes, there is the possibility that
you can control the inside-the-cell production of proteins.
Thus, there is the possibility of correcting genetic disorders
or treating a variety of medical conditions. This is the whole
idea of "gene therapy".
