A History of Proteins
Linus Pauling is credited with the successful prediction of regular protein secondary structures based on hydrogen bonding, an idea first put forth by William Astbury in 1933. Later work by Walter Kauzmann on denaturation, based partly on previous studies by Kaj Linderstrøm-Lang, contributed an understanding of protein folding and structure mediated by hydrophobic interactions. In 1949 Fred Sanger correctly determined the amino acid sequence of insulin, thus conclusively demonstrating that proteins consisted of linear polymers of amino acids rather than branched chains, colloids, or cyclols. The first atomic-resolution structures of proteins were solved by X-ray crystallography in the 1960s and by NMR in the 1980s. As of 2006, the Protein Data Bank has nearly 40,000 atomic-resolution structures of proteins. In more recent times, cryo-electron microscopy of large macromolecular assemblies and computational protein structure prediction of small protein domains are two methods approaching atomic resolution.
Protein is one of the most vital of all the basic nutrients for your body. They are complex molecules made up of building blocks called amino acids; to put it simply, protein is your body’s building material. You need this nutrient to provide your body with the materials it needs to build, repair, and maintain your lean muscle. Lean muscle is not the only thing protein builds and maintains, it is also responsible for maintaining tissues, enzymes, hormones, skin, nails, hair and much more.
You want to make sure that your protein comes from the right source and in the right amounts. Some proteins, mostly from animal sources, contain a high amount of saturated fat, which will not only hamper your weight loss plan but it can have a detrimental effect on your health. High quality protein sources include some of the following:
o Lean Meats
o Fish
o White meat chicken
o Turkey
o Eggs
o Legumes
o Beans
