The defining feature of an amino acid is its side chain (at top, blue circle; below, all colored circles). When connected together by a series of peptide bonds, amino acids form a polypeptide ...

Each protein is a molecule made up of different combinations of 20 types of smaller, simpler amino acids. Protein molecules are long chains of amino acids that are folded into a three-dimensional ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

BCAAs, short for branch-chain amino acids, are three types of essential amino acids. BCAA benefits include reduced fatigue, muscle soreness, and helping with weight loss. Use a BCAA supplement ...

Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal ...

Essential Amino Acids (EAA) and Branched-Chain Amino Acids (BCAA ... such as ALS (Amyotrophic Lateral Sclerosis), maple syrup urine disease, or certain liver problems, should use BCAA supplements ...

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The ...

A rare mutation that leads to high CREB3 activity is associated with a reduced risk of developing ALS and slower disease ...
