N2 - 2-(2-Furoyl)-4(5)-(2-furanyl)-1H-imidazole (FFI) is a fluorescent molecule which was originally discovered in chloroform extract of ammoniacal solution of acid-hydrolyzed glycated proteins and proposed to represent a protein cross-link. The absence of a lysyl residue side chain and other observations prompted a detailed study of its mechanism of formation. Glycated α-t-Bytoxycarbonyllysine was incubated for 29 days and periodically assayed for FFI and FFI-like fluorescence. Whereas fluorescence increased over time, FFI recovery was unexpectedly highest on day 0 and lowest on day 29, suggesting that FFI was directly derived from Amadori products. FFI was also recovered from hydrolysates of glycated neopentylamine, furosamine, and browned poly-L-lysine but was virtually undetectable in similar solutions basified with NaOH, triethylamine, or pyridine instead of ammonia. Gas chromatography-mass spectrometry analysis of FFI from similar hydrolysates basified in the presence of 15N-enriched NH4Cl revealed for all precursors a parent ion peak at 230 instead of 228 m/e units, suggesting that the two imidazole nitrogen atoms had been incorporated from free ammonia into FFI. Spontaneous FFI synthesis occurred when furosine was reacted with aqueous ammonia at room temperature. These results do not support the proposition that FFI is an advanced glycosylation end product or a protein cross-link. They suggest that FFI is formed from ammonia and furosine which are by-products of acid-hydrolyzed glycated proteins.
The ScrumMaster is often someone with a background in project management, but the role can also be filled by a technical specialist. The ScrumMaster is not only a coach, but also a protector of the team. If the product owner is demanding too much, the ScrumMaster must recognize this and help the team members avoid overextending themselves. At the other extreme, if the team members become lackadaisical, the ScrumMaster must address this, too.

Oops, meant phenyl/benzyl-containing. Although I’m not actually a synthetic chemist, so I might be completely off base. But presumably there are some phenyl/benzyl containing protecting groups that have good cleavage yields?
The major steps of protein synthesis are: ..
Striking article, Derek. With the advent of computational modeling I think we are starting to see the “new wave” in other areas of biology and medicine as well. Predictable enzyme function, protein folding, so on and so forth.
Add in modular semi-automated synthetic chemistry and I think we are starting to see the shape of the future for much of the ‘routine’ research currently being performed.

The product owner needs to have a clear understanding of the market, competitors, trends, and the end users. Often the product owner is a lead end user, but it could also be someone in product development and/or marketing.
Amino acid synthesis is the set of biochemical processes ..
Translation is the process of RNA forming protein.
Once the mRNA has travelled to the ribosomes,the tRNA reads the mRNA in threes of nucleotide bases called codons.

Many enzymes become popular after someone writes an article praising their wonderful abilities to manipulate molecular behavior - ingestion of the enzyme is usually recommended. Superoxide dysmutase is one popular enzyme which cannot be delivered by oral intake to the intercellular sites where it does its useful things. Ingested proteins tend to get digested, losing their information as shape and function, or, if they are not digested, tend to cause allergic reactions rather than functioning normally. The next development of molecular engineering will be vehicles to deliver enzymes to intracellular sites where they will be useful. Delivery vehicles may be physical structures or carrier molecules that protect the enzymes while directing them through the GIT, circulation, and filtering systems such as the liver and lungs.
