Fish protein hydrolysates were prepared from Cuttlefish (Sepia pharaonis) muscle using alcalase and protamex methods. By conducting the Cuttlefish protein hydrolysate using alcalase (CPHA), it showed higher degrees of hydrolysis, proximate composition, yield, emulsifying activity index (EAI), emulsion stability index (ESI), foaming activity index (FAI), solubility, water holding capacity (WHC) ...

The role of the kidney in the metabolism of parathyroid hormone (PTH) was examined in the dog. Studies were performed in awake normal and uremic dogs after administration of bovine parathyroid hormone (b-PTH) or synthetic amino terminal tetratricontapeptide of b-PTH (syn b-PTH 1-34). The renal clearance of immunoreactive PTH was determined from the product of renal plasma flow and the percent e...

Background. The newer parathyroid hormone (PTH) assay, whole-PTH, uses an antibody that binds the region harbouring the first amino acid, making it specific for the complete molecule, 1-84-PTH. Especially among dialysis patients, it has been reported that the level of whole-PTH can be calculated as ∼60% of their intact-PTH value. In addition, since 1-84-PTH is part of intact-PTH, the whole-PTH/...

a simple and efficient one-pot, three-component strecker reaction of protected amino acids, aromatic aldehydes, and trimethylsilyl cyanide has been developed for the synthesis of chiral α-amino nitriles. the reaction was carried out in the presence of catalytic amount of phosphotungstic acid (h3[p(w3o10)4]) as an environmentally friendly catalyst.

based on the randic suggestion of the resolution of a structure into shape, size, and function an index representing structure-catabolic fate relationships of amino acids is constructed. the index obtained by multiplying three factors; (nb2 + nr), nc and m; representing shape, size and function respectively, where nb2 = number of double bonds, nr = number of rings, nc = number of carbon atoms, ...

a pancreatopeptidase (elastase) digest index was devised for a rapid and accurate estimation of protein quality. this index was calculated on the basis of all the amino acids released by an in-vitro elastase digestion, acid hydrolyses of same sample and the residue of enzyme hydrolyzed. the amino acids were determined by thin-layer chromatography. samples used were cooked white kidneybeans, coo...

We have developed a highly sensitive, two-site immunoradiometric assay (IRMA) for human parathyrin (PTH) that is specific for the intact, secreted, biologically active 84-amino-acid peptide. This assay has several technical advantages: it does not detect even high concentrations of inactive carboxyl-terminal fragments, results are available within 24 h, and the detection limit for intact hormon...
