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 ...

The purpose of protein synthesis is simply to create a polypeptide -- a protein made out of a chain of amino acids. In a hair follicle cell, a protein called keratin is made. Lots of it.

Amino acids are joined together by peptide bonds to form polypeptide chains. The sequence of amino acids in a protein, known as its primary structure, is determined by the genetic code. This sequence ...

Results revealed that LH1-LH2 and LH1-RC complexes are formed, the smallest unit of the LH1 structure is composed of an unusual polypeptide chain, and this LH1 structure surrounds LH2 or RC.

Researchers have investigated the structure and light energy transfer efficiency of a protein complex crucial to the photosynthesis of purple sulfur bacteria thriving in high-salt, high-alkaline ...
