Help: what is amino peptide??

[chinamadmonk]

I read an abstract which mentioned "amino peptide", could anyone tell me what does the "amino peptide" mean in that article(I can not read Russian)?? I am puzzled:Is there any peptide with only N-end or C-end？？

 

Cultivation of Haemophilus influenzae, serotype B, in amino peptide-based semisynthetic nutrient medium]

The work shows the possibility of the cultivation of H. influenzae, serotype b, in semisynthetic nutrient medium with amino peptide as the only source of amino acids, glucose--as the main source of carbon and energy and containing, in addition, the necessary growth factors and vitamins.

generaly it`s peptide-NH2

the NH2 is bonded to a carbon IIRC.

I assume it is the same as peptide.

Thanks for you all, I guess it means peptide too, but it is still not confirmed from original article.

Yeah, peptides always have amino groups so the name is kinda weird. I checked some articles in which amino peptides were mentioned. It appears that they are mostly found in nutrition or medical journals, but what from what I have seen they still simply referred to normal peptides.

It could also mean that the peptides they were dealing with were amino rich.

 

For example: they could be made up of predominantly lysine and arginine.
