There are cases where itâs an easy decision. If the car is 20 years old with 300,000 miles on it and is falling apart at the seams then itâs pretty obvious it makes no sense to fix it. If the car is 5 years old and in good shape itâs definitely worth fixing. Most of the cars that need engines fall somewhere in-between.
Carnosine is a small protein composed of the amino acids histidine and alanine. It is found in relatively high concentrations in several body tissues, most notably in skeletal muscle, heart muscle, and the brain.
Lysine (abbreviated as Lys or K) is an Î±- amino acid with the chemical formula HO 2 CCH(NH 2)(CH 2) 4 NH 2. It is an essential amino acid for humans. Lysine's codons are AAA and AAG. Lysine is a base, as are arginine and histidine. The Îµ-amino group often participates in hydrogen bonding and as a general base in catalysis. (The Îµ-amino group (NH 3 +) is attached to the fifth carbon from the Î±-carbon, which is attached to the carboxyl (C=OOH) group.
