Any of the protein constituents of lipoproteins; grouped by function in four classes.

A protein that precipitates from solution when cooled and redissolves upon warming.

An antigen present in the human fetus and in certain pathological conditions in adults.

The amniotic fluid level can be used to evaluate fetal development. Elevated serum levels are found in adults with certain kinds of liver diseases.

An excess of lipoproteins (any of the lipid-protein, or fat-protein, complexes in which lipids or fats) in the blood, resulting from a disorder of lipoprotein metabolism; it may be an acquired or familial condition or some combination.

Decreased levels of a lipoprotein in the serum.

1. Any of the lipid-protein complexes in which lipids are transported in the blood.
2. A molecule that is a combination of lipid and protein.

Lipids don't travel in the blood by themselves; however, they are carried through the bloodstream as lipoproteins.

1. A complex protein found in mucous secretions.
2. Any of a group of organic compounds; such as, the mucins, that consist of a complex of proteins and glycosaminoglycans and are found in body tissues and fluids.

A large molecule composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein.

Proteins are required for the structure, function, and regulation of the body's cells, tissues, and organs. Each protein has unique functions. Proteins are essential components of muscles, skin, bones and the body as a whole.

Examples of proteins include whole classes of important molecules, among them enzymes, hormones, and antibodies.

Protein is one of the three types of nutrients used as energy sources by the body, the other two being carbohydrate and fat. Proteins and carbohydrates each provide four calories of energy per gram, while fats produce nine calories per gram.

The word "protein" was introduced into science by the great Swedish physician and chemist, Jöns Jacob Berzelius (1779-1848), who also determined the atomic and molecular weights of thousands of substances, discovered several elements including selenium, first isolated silicon and titanium, and created the present system of writing chemical symbols and reactions.

Etymology: from French protéine, from Greek proteios, "the first quality"; from protos, "first". Originally a theoretical substance thought to be essential to life, the modern use is from German Protein, borrowed in English about 1907.

An intense dislike of or aversion to protein foods.

1. The comprehensive analysis of the identity, interactions and locations of proteins within a cell.
2. The analysis of the expression, localization, functions, and interactions of the proteins produced by the genes of an organism.
3. The qualitative and quantitative study of the proteome (complete set of proteins produced from the information encoded in a genome) under various conditions, including protein expression, modification, localization, and function; and protein–protein interactions, as a means of understanding biological processes.

Proteomics is the study of the way proteins work inside cells, and how they interact with each other. Most importantly, it aims to work out the differences in protein action between diseased cells and healthy ones.

One aim is to find chemical markers to determine what’s going wrong when disease strikes and to diagnose disorders; another is to find methods of gene therapy that will cure the problems at the level of the DNA in human genes.

The first announcement of a Savior, as made in the Garden of Eden immediately after the Fall.
