Determination of methylated basic amino acids with the amino acid analyzer. Application to total acid hydrolyzates of myelin basic proteins.
A procedure is described for the direct determination of methyl derivatives of basic amino acids in total acid hydrolyzates of proteins by the use of a Beckman amino acid analyzer operated in the high sensitivity mode with automatic integration. The conditions described permit the separation of ornithine, lysine, 5-hydroxylysine, N’-monomethyllysine, N”-dimethyllysine, histidine, N’-methylhisti...
متن کاملAvailable lysine and digestible amino acid contents of proteinaceous foods of India.
Cereals and legumes are staple foods in India and are limiting in lysine and sulphur amino acids, respectively. Available lysine loss, due to Maillard-type reactions that may occur during food preparation, exacerbates the problem of lysine deficiency particularly in cereals. Consequently, determining the contents of digestible essential amino acids, particularly lysine, is important. True ileal...
متن کاملDetermination of amino acid requirements of young pigs using an indicator amino acid.
Mixtures of skim milk and free amino acids were compared as diets for pigs which would allow manipulation of dietary amino acid levels. Piglets gained 208 g/d between 3 and 14 d of age on the skim-milk diet, but replacement of 600 g/kg of the dietary nitrogen with free amino acids reduced growth rate to 148 g/d. Supplementation of a lysine-deficient diet with lysine reduced the catabolism of [1...
متن کاملVoltammetric Determination of Cysteine (2-amino-3-mercaptopropanoic acid, CySH) by Means of 4 4'-biphenol as a Homogeneous Mediator
In the present research, 4, 4'-biphenol was used as a homogeneous mediator for determining cysteine (CySH) on a Glassy Carbon Electrode (GCE). To describe the electrochemical properties of 4,4'-biphenol and to examine its electrocatalytic impacts on cysteine oxidation, both Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) were employed. Our findings revealed that 4,4'-biphenol could s...
متن کاملLysine from cooked white rice consumed by healthy young men is highly metabolically available when assessed using the indicator amino acid oxidation technique.
Cooked white rice (CWR) provides up to 71% of the dietary protein for many people worldwide. The protein digestibility-corrected amino acid (AA) score is the method adopted by FAO/WHO to evaluate protein quality. Our group has proposed the metabolic availability (MA) of AAs as another determinant of protein quality. It measures the percentage of an indispensable AA that is incorporated during p...
