  • The cleavage of oxidized insulin B chain tended to occur at sites where the P1 amino acid was bulky and non-polar, and the P1′ amino acid was bulky and polar, such as its primary cleavage site of Val2-Asn3. (biochemj.org)
  • Therefore, both the specific requirements for non-essential amino acids and the value of these amino acids in supplying the organism with non-specific nitrogen should be taken into account when studying the optimum E:T ratio and formulating amino acid diets . (karelsavry.us)
  • However, as discussed earlier, the maintenance requirement for nonessential N is relatively high and the synthesis of some non-essential or semi-essential amino acid(s) may not be sufficient to meet endogenous losses and specific requirements not related to protein metabolism. (karelsavry.us)
  • It was the aim of this study to examine the abundant myelin protein, myelin basic protein (MBP), to determine if there are sites of modification that may be characteristic for MS. MBP from the cerebellum was examined from controls and MS patients across the age range using mass spectrometry and amino acid analysis. (biomedcentral.com)
  • Amino acid racemization data indicated that myelin basic protein is long-lived and proteomic analysis of MBP showed it to be highly modified. (biomedcentral.com)
  • specific
  • It is insensitive to pepstatin, but is sensitive to the other aspartic proteinase-specific inhibitors diazoacetyl-DL-norleucine methyl ester (DAN) and 1,2-epoxy-3-(p-nitrophenoxy)propane. (biochemj.org)
  • To date, it is not known whether there is a specific requirement for non-essential and semi-essential amino acids for maintenance. (karelsavry.us)
