Life is all about bags of biochemical reactions
Proteins are the most structurally and functionally diverse group of biomolecules. They also make up the majority of the dry weight of all living cells.
Proteins are used as motors, structural elements, enzymes, receptors, channels through membranes, intra-cellular transporters, regulatory switches, and much more.
alanine, valine, leucine, isoleucine, proline, methionine, phenylalanine, tryptophan
glycine, serine, threonine, cysteine, asparagines, glutamine, tyrosine
The segments of helix, sheets, and turns then interact to form the overall structure of the molecule (tertiary structure).
Multiple polypeptide chains can come together to form complex multi-subunit molecular machines (quaternary structure).
