Pyrroloquinoline Quinone
Pyrroloquinoline quinone (PQQ), also called methoxatin'','' is a redox cofactor and antioxidant. Produced by bacteria, it is found in soil and foods such as kiwifruit, as well as human breast milk. Enzymes using PQQ as a redox cofactor are called quinoproteins and play a variety of redox roles. Quinoprotein glucose dehydrogenase is used a glucose sensor in bacteria. PQQ stimulates growth in bacteria. Eukaryote targets, including mammalian lactate dehydrogenase, are of more interest to health. It is suggested that PQQ taken as a dietary supplement could promote mitochondrial biogenesis via this pathway as well as PGC-1α. History It was discovered by J.G. Hauge as the third redox cofactor after nicotinamide and flavin in bacteria (although he hypothesised that it was naphthoquinone). Anthony and Zatman also found the unknown redox cofactor in alcohol dehydrogenase. In 1979, Salisbury and colleagues as well as Duine and colleagues extracted this prosthetic group from methanol d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Invitation To Tender
An invitation to tender (ITT, otherwise known as a call for bids or a request for tenders) is a formal, structured procedure for generating competing offers from different potential suppliers or contractors looking to obtain an award of business activity in works, supply, or service contracts, often from companies who have been previously assessed for suitability by means of a supplier questionnaire (SQ) or pre-qualification questionnaire (PQQ). The term "notice inviting tenders" (NIT) is often used in purchasing in India. An ITT differs from a request for quotation (RFQ) or a request for proposal (RFP), in which case other reasons (technology used, quality) might cause or allow choice of the second best offer. An RFP is a request for a price from a buyer but the buyer would also expect suggestions and ideas on how the project work should be done. RFPs are thus focused on more than just pricing/cost, they entail a bit of consulting from the contractor or vendor. The closest equi ...
