Eagle's minimal essential medium: Eagle's minimal essential medium (EMEM) is a cell culture medium developed by Harry Eagle that can be used to maintain cells in tissue culture.Proteinogenic amino acid: Proteinogenic amino acids are amino acids that are precursors to proteins, and are incorporated into proteins cotranslationally — that is, during translation. There are 23 proteinogenic amino acids in prokaryotes (including N-Formylmethionine, mainly used to initiate protein synthesis and often removed afterward), but only 21 are encoded by the nuclear genes of eukaryotes.MultivitaminThiamine transporter: Members of this protein family have been assigned as thiamine transporters by a phylogenomic analysis of families of genes regulated by the THI element, a broadly conserved RNA secondary structure element through which thiamine pyrophosphate (TPP) levels can regulate transcription of many genes related to thiamine transport, salvage, and de novo biosynthesis. Species with this protein always lack the ThiBPQ ABC transporter.PurineTrace metal: Trace metals are metals that can be present in animal and plant cells and tissue and are a necessary part of nutrition and physiology. Ingestion of, or exposure to, excessive quantities can be toxic.Casein: Casein ( or , from Latin caseus, "cheese") is the name for a family of related phosphoproteins (αS1, αS2, β, κ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow milk and between 20% and 45% of the proteins in human milk.Nitrogen deficiencyMayo Clinic Diet: The Mayo Clinic Diet is a diet created by Mayo Clinic. Prior to this, use of that term was generally connected to fad diets which had no association with Mayo Clinic.Neisseria gonorrhoeae: Neisseria gonorrhoeae, also known as gonococci (plural), or gonococcus (singular), is a species of Gram-negative coffee bean-shaped diplococci bacteria responsible for the sexually transmitted infection gonorrhea.Protein toxicity: Protein toxicity with proteinuria can result in those with preexisting kidney disease, or those who have lost kidney function due to age.List of countries by food energy intake: Food consumption refers to the amount of food available for human consumption as estimated by the FAO Food Balance Sheets. However the actual food consumption may be lower than the quantity shown as food availability depending on the magnitude of wastage and losses of food in the household, e.Glucose transporterButyl acetate (disambiguation): Butyl acetate most often refers to n-butyl acetate. However, there are other isomers that may be considered to be butyl acetates:Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.MethionineLactic acid fermentationReplica plating: 350px|right|thumb|[[Negative selection (artificial selection)|Negative selection through replica plating to screen for ampicillin sensitive colonies]]List of strains of Escherichia coli: Escherichia coli is a well studied bacterium that was first identified by Theodor Escherich, after whom it was later named.Coles Phillips
