Unknown Bio Terms

  1. glutamate- "excitatory neurotransmitter in the mammalian central nervous system"
  2. glutamine- "crystalline amino acid occurring in proteins; important in protein metabolism. One of the 20 amino acids that are commonly found in proteins"
  3. flux- "amount of a quantity passing through a given surface per unit time. Typical quantities include (magnetic) field lines, particles, heat, energy, mass of fluid, etc. (Knew term based off of physics and Math 234, wasn't sure if applied to bio as well)"
  4. proline- "One of the 20 amino acids directly coded for in proteins. Secondary amine and so proline is described as an imino acid. Has strong influence on secondary structure of proteins and is much more abundant in collagens than in other proteins, occurring especially in the sequence glycine proline hydroxyproline"
  5. urea- "final nitrogenous excretion product of many organisms. The chief solid component of mammalian urine; synthesized from ammonia and carbon dioxide and used as fertilizer and in animal feed and in plastics.A molecules created from ammonia and carbon dioxide as a result of the urea cycle"
  6. acetaldehyde-"colourless, flammable liquid used in the manufacture of acetic acid, perfumes, and flavors. It is also an intermediate in the metabolism of alcohol. It has a general narcotic action and also causes irritation of mucous membranes"
  7. alpha ketoglutarate- definition for "alpha amino acid":"amino acid of the general formula R-CHNH2-COOH (i.e., the NH2 in the a position); the l forms of these are the hydrolysis products of proteins. In rarer usages, this class of molecules also includes alpha-amino phosphoric acids and alpha-aminosulfonic acids." Based off of this, I am assuming that the alpha ketoglutarate is a specialized amino acid version of the glutamate neurotransmitter, perhaps with an extra NH2 branch or an added acid
  8. permease-encoding- permease: "type of protein believed to be involved in active transport and acts as a protein carrier" so, the specific biological coding genes that create permease proteins"
  9. oligonucleotide-"linear sequence of up to 20 nucleotides joined by phosphodiester bonds. Above 20, the term polynucleotide begins to be used. A short sequence of nucleotides"
  10. proline permease- "PRNB isolated from Aspergillus nidulans"
