N-Acetylcarnosine acetate (N-Acetyl-L-carnosine acetate), a natural histidine-containing dipeptide, is a source of pharmacological principal L-carnosine. N-Acetylcarnosine is a potent ophthalmic drug in human cataracts

Hexa His is an amino acid sequence consisting of 6 His residues in a row, it is also known as hexa histidine-tag, 6xHis-tag, and by the trademarked name His-tag. Hexa His Responsible for the degradation of GM2 gangliosides, and a variety of other molecule

N-Acetylcarnosine (N-Acetyl-L-carnosine) is thought to be able to combat some of the effects of oxidative stress as it has anti-oxidant properties.

Anserine (L-Anserine) is a dipeptide containing β-alanine and histidine, which can be found in the skeletal muscle and brain of mammals and birds. Anserine is not cleaved by serum carnosinase and act as biochemical buffers, chelators, antioxidants, and anti-glycation agents. Anserine improves memory functions in Alzheimer's disease (AD)-model mice.
