For the first time, the three-dimensional structure of a protein hormone, insulin, has been worked out by x-ray crystallographio analysis using isomorphous replacement and anomalous scattering methods. The basic repeating unit in the crystals studied is an insulin hexamer. The three dimers in the...
is a unique characteristic of every protein ?is encoded by the nucleotide sequence of DNA ?is thus a form of genetic information ?is read from the amino terminus to the carboxyl terminus 1o structure =linear amino acid sequence For the Insulin A chain, the 1o structure is: Gly-Ile-Val-...
Amino acid sequence of bovine insulin. The two polypeptide chains are joined by disulfidecross-linkages (yellow). The A chain of insulin is identical in human, pig, dog, rabbit, and sperm whale insulins. The B chains of the cow, pig, dog, goat, and horse are identical. Ⅳ. Protein Ch...

However, there are many proteins that consist of more than one polypeptide chain. These are called oligomeric proteins, in which each chain constitutes a subunit of the protein complex. For example, insulin is composed of two subunits, while hemoglobin and lactate dehydrogenase are composed of ...

One dalton is the molecular mass of one hydrogen atom. The molecular weight of a protein is equal to the addition of the molecular weights of the amino acids constituting the protein. Some proteins are of relatively small molecular size, such as insulin, with a molecular weight of about 5,...
