2. Lysine - Wikipedia

   en.wikipedia.org/wiki/Lysine

   Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.It contains an α-amino group (which is in the protonated −NH + 3 form when dissolved in water), an α-carboxylic acid group (which is in the deprotonated −COO − form when dissolved in water), and a side chain lysyl ((CH 2) 4 NH 2), classifying it as a basic, charged (at physiological pH), aliphatic ...

3. Essential amino acid - Wikipedia

   en.wikipedia.org/wiki/Essential_amino_acid

   An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized from scratch by the organism fast enough to supply its demand, and must therefore come from the diet. Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are valine, isoleucine, leucine, methionine ...

   Airborne is an American brand of dietary supplement containing herbal extracts, amino acids, antioxidants, electrolytes, vitamins, and other ingredients originally marketed as preventing the common cold and improving immune function. [1] The benefits of its use are unsupported by robust clinical research. [1]

5. Copper peptide GHK-Cu - Wikipedia

   en.wikipedia.org/wiki/Copper_peptide_GHK-Cu

   Infobox references. Copper peptide GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl- L -histidyl- L -lysine. The tripeptide has strong affinity for copper (II) and was first isolated from human plasma. It can be found also in saliva and urine.

6. Amino acid synthesis - Wikipedia

   en.wikipedia.org/wiki/Amino_acid_synthesis

   Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced. The substrates for these processes are various compounds in the organism 's diet or growth media. Not all organisms are able to synthesize all amino acids. For example, humans can synthesize 11 of the 20 standard amino acids.

7. Lysin - Wikipedia

   en.wikipedia.org/wiki/Lysin

   Double-stranded DNA phage lysins tend to lie within the 25 to 40 kDa range in terms of size. A notable exception is the streptococcal PlyC endolysin, which is 114 kDa. PlyC is not only the biggest and most potent lysin, but also structurally unique since it is composed of two different gene products, PlyCA and PlyCB, with a ratio of eight PlyCB subunits for each PlyCA in its active conformation.
