The mitochondrial pyruvate dehydrogenase complex (mtPDC) plays a pivotal role in controlling the entry of carbon into the tricarboxylic acid (TCA) cycle for energy production. This multi-enzyme ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein ...

mTORC1 carries out its role by regulating certain anabolic (synthetic) and catabolic (degradative) processes. These involve protein synthesis; production of the protein-synthesis machinery in the form ...

The discovery of ribosomes dates back to the 1950s, when George Palade first observed dense particles in the cytoplasm of cells using electron microscopy. These particles were later named "ribosomes" ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 87, No. 4 (Feb., 1990), pp. 1347-1351 (5 pages) Two peptides, corresponding to amino acids 1-17 and 169-186 of the ...

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...

Amino acids are the building blocks of protein. These molecules come together to form proteins. Your body uses them for many important functions, such as making hormones, building muscle, and ...

The body needs 20 different amino acids to maintain good health and normal functioning. People must obtain nine of these amino acids, called the essential amino acids, through food. Amino acids are ...

Protein is an important food group to include in your diet. Your body needs protein to build bones, muscles, cartilage, and skin. It also needs protein to repair cells and tissues, make and regulate ...
