Proteins in food are long chains of amino acids that are broken down during digestion.
Polypeptides, which are the next stage in protein digestion, are shorter chains
Peptides are chains with even fewer links, which then break down into constituent amino acids
Individual amino acids are finally reassembled into the new proteins that are needed.
Breaking down and reassembling [...]
Individual proteins are made up of various combinations of at least 50, and up to several thousand, amino acids strung together in a long chain. A complete protein depends upon this chain of amino acids gathering into a highly complex, multi-layered string, and then going on to twist itself into intricate
three-dimensional shapes. Proteins can be [...]
Think of your body as a mechanism made up of billions of tiny chemical factories linked in an endless
process of utilising energy and performing such functions as nerve transmission and producing vital enzymes (body substances made from proteins that break down foods and regulate metabolism). Something as complicated as the human body must inevitably require [...]
