Protein molecules are long, usually folded chains composed
mostly of amino acids and are made of C, H, O, and N.
Protein molecules assemble fats and carbohydrates; they
function as enzymes, structural components, and hormones.
The function of each protein molecule depends on its
specific sequence of amino acids and the shape of the
molecule.
- Learning
About Proteins New
Your body uses the protein you eat to make lots of
specialized protein molecules that have specific jobs.
For instance, your body uses protein to make hemoglobin.
The site contains a section on amino acids.
- Proteins
New
Proteins are macromolecules. They are constructed
from one or more unbranched chains of amino acids;
that is, they are polymers. A typical protein contains
200–300 amino acids but some are much smaller
(the smallest are often called peptides) and some
much larger. Every function in the living cell depends
on proteins.
- Biomolecules
- Proteins New
This site has an interactive
activity that explains proteins and much more.
B2.3 Maintaining Environmental Stability
