Amino Acids: “Building Blocks” of ProteinREAD MORE
Moreover, once a construction is erected, it can then be deconstructed without destroying the individual pieces — and the pieces used again to create entirely new structures.
In the process of protein metabolism, the amino acid blocks are repeatedly disassembled and reassembled. The destructive and constructive phases (catabolism and anabolism, respectively) give shape, form, and purpose to the proteins that make life possible.
The Amino Acid Family
Though over 500 amino acids have been discovered in nature, just 20 of them are integral to our constitution.

Amino Acid MultiplicationREAD MORE
With three amino acids (a tripeptide), 8000 combinations. Variables include the number and type of amino acids combined; their sequence along a chain; the number of peptide bonds linking them together; the shapes assumed as polypeptide chains fold; and the three-dimensional structure of a chain or of multiple chains linked together.
