(From Wikipedia, the free Encyclopedia)
Proteins (originally meaning first thing when discovered in 1838 by Berzelius) are one of the primary constituents of living things and viruses, and as such are one of the chief classes of molecules studied in biochemistry. As enzymes, proteins are often considered the "machines of the cell." They are an important component of human nutrition.
Nutrition
Proteins can be used for energy, but they must first be converted to common metabolic intermediates. This releases ammonia, an extremely toxic substance. It is then converted in the liver into urea, a much less toxic chemical, which is excreted in urine. Some animals convert it into uric acid instead.Nutritionally, proteins come in two forms: complete proteins contain all eight of the essential amino acids while incomplete protein is missing at least one. The human body requires 14 other amino acids, which it can synthesize from the essential amino acids. Animal-derived foods contain all of those amino acids, while plant sources do not. That is why vegans must mix their protein sources. Ovo-lacto vegetarians usually do not have this problem, since egg's white and cow's milk contain all essential amino acids, as well as soy milk. Legumes, the alga spirulina and some grains are the richest sources of plant protein.
Proteins differ from carbohydrates chiefly in that they contain much nitrogen and a little bit of sulfur, besides carbon, oxygen and hydrogen.
Biochemistry
A protein molecule is an unbranched biopolymer composed of many amino acids linked together in a chain. The chain folds into a 3-dimensional structure known as the native state, which is determined by its sequence of amino acids. There are four levels of protein structure:In addition to these levels of structure, proteins may shift between several similar structures in performing of their biological function. In the context of these functional rearrangements, these tertiary or quaternary structures are usually referred to as "conformations," and transitions between them are called conformational changes.
- Primary structure: the amino acid sequence
- Secondary structure: structures stabilized by hydrogen bonds between the C=O and N-H groups of different amino acids
- Tertiary structure: structures stabilized by interactions between the amino acid side chains of a single protein molecule
- Quaternary structure: structures resulting from the union of more than one protein molecule, called subunit proteins' or subunits in this context, which function naturally only when part of the larger assembly.
The primary structure is held togaether by covalent peptide bonds, which are made during the process of translation. The process by which the higher structures form is called protein folding and is a consequence of the primary structure. Although any unique polypeptide may have more than one stable folded conformation, each conformation has its own biological activity and only one conformation is considered to be the active, or native conformation.
If a region of a protein has any secondary structure, it is either an alpha helix or beta sheet. The random regions are called random coils. The string is folded further into larger 3-dimensional structures that are held together by hydrogen bonds, hydrophobic interactions, ionic interactions, and/or disulfide bonds.
Proteins are generally large molecules, sometimes having molecular masses of up to 3,000,000 (the muscle protein titin has a single amino acid chain 27,000 subunits long). Such long chains of amino acids are almost universally referred to as proteins, but shorter strings of amino acids are referred to as "polypeptides," "peptides" or very rarely "oligopeptides". The dividing line is somewhat undefined, although a polypeptide may be less likely to have tertiary structure and may be more likely to act as a hormone (like insulin) rather than as an enzyme or structural element.
Proteins are generally classified as soluble, filamentous or membrane-associated (see integral membrane protein). Nearly all the biological catalysts known as enzymes are proteins. (Certain RNA sequences were shown in the late 20th century to have catalytic properties as well.) Membrane-associated exchangers and ion channels, which move their substrates from place to place but do not change them; receptors, which do not modify their substrates but may simply shift shape upon binding them; and antibodies, which appear to do nothing more than bind, all are proteins as well. Finally, the filamentous material that makes up the cytoskeleton of cells and much of the structure of animals is also protein: collagen and keratin are components of skin, hair, and cartilage; and muscles are composed largely of proteins.
Proteins can be picky about the environment in which they are found. They may only exist in their active, or native state, in a small range of pH values and under solution conditions with a minimum quantity of electrolytes, as many proteins will not remain in solution in distilled water. A protein that loses its native state is said to be denatured. Denatured proteins generally have no secondary structure other than random coil. A protein in its native state is often described as folded.
One of the more striking discoveries of the 20th century was that the native and denatured states in many proteins were interconvertible, that by careful control of solution conditions (by for example, dialyzing away a denaturing chemical), a denatured protein could be converted to native form. The issue of how proteins arrive at their native state is an important area of biochemical study, called the study of protein folding.
Through genetic engineering, researchers can alter the sequence and hence the structure, "targeting, susceptibility to regulation and other properties of a protein. The genetic sequences of different proteins may be spliced together to create "chimeric proteins that possess properties of both. This form of tinkering represents one of the chief tools of cell and molecular biologists to change and to probe the workings of cells. Another area of protein research attempts to engineer proteins with entirely new properties or functions, a field known protein engineering.
Protein deficiency is often discussed in relation to nutrition especially as it relates to starvation and malnourishment in third world countries. It may be an overlooked health factor even in developed countries such as the United States, where diets may rely heavily on carbohydrates, may lack essential amino acids, and there is societal pressure to be thin. Protein deficiency can lead to symptoms such as fatigue, insulin resistance, hair loss, loss of hair pigment (hair that should be black becomes reddish), loss of muscle mass (proteins repair muscle tissue), low body temperature, and hormonal irregularities. Severe protein deficiency is fatal.
Excess protein can cause problems as well, such as foundering (foot problems) in horses.
Proteins can often figure in allergies and allergic reactions to certain foods. This is because the structure of each form of protein is slightly different, and some may trigger a response from the immune system while others are perfectly safe. Many people are allergic to the particular proteins found in peanuts, or those in shellfish or other seafoods, for example, but it is extremely unusual for the same person to react to all three.

(From Wikipedia, the free Encyclopedia)
Protein in the context of nutrition is distinct from protein in the context of biochemistry. The former is really eight essential amino acids which are used by the body to manufacture the latter as needed.All eight essential amino acids must be part of one diet in order to survive and are needed in a fixed ratio. A shortage on any one of these amino acids will constrain the body's ability to make the proteins it needs to function.
Different foods contain different ratios of the essential amino acids. By mixing foods that are rich in some amino acids with foods that are rich in others, one can acquire all the needed amino acids in sufficient quantities. Omnivores typically eat a sufficient variety of foods that this is not an issue, however, vegetarians and especially vegans should be careful to eat appropriate combinations of foods (e.g. nuts and green vegetables) so as to get all the essential amino acids in sufficient quantities that the body may produce all the proteins that it needs.

 | This is a scanning electron microscope image from normal circulating human blood. One can see red blood cells, several white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shaped platelets. Red cells are nonnucleated, and contain hemoglobin, containing iron an important protein which allows the cell to carry oxygen to other parts of the body. They also carry away carbon dioxide from the lungs. The infection-fighting white blood cells, are classified in 2 main groups: granular and agranular. Granulocytes are formed in bone marrow, agranulocytes are produced by lymph nodes and spleen. There are two types of agranulocytes: lymphocytes, fight disease by producing antibodies and thus destroying foreign material, and monocytes. Platelets are tiny cells formed in bone marrow and are necessary for blood clotting. Credit: Bruce Wetzel (photographer).
