Nutrition and amino acid composition of a rumen bacterium
… that mixture of the basic structural molecules ( amino acids, purines, and pyrimidines ) which most closely approximates the composition of the organism itself. 2. To apply this hypothesis toward the goal set in the first objective.

Intrinsic Disorder and Protein Evolution: Amino Acid Composition of Proteins in Last Universal Ancestor
All twenty amino acids did not appear simultaneously in nature. Instead some of them appeared early, while others were added into the genetic code later. The amino acids that were formed by Miller (1953) are suggested to have appeared early in evolutionary history, and the amino acids associated …

The amino acid composition of chinchilla fur in relation to the fur-chewing syndrome
Amino acids were determined in two types of chinchilla fur (chewed and normal), using three methods for analyses The methods included microbiological assays of Barton-Wright(5) and two column chromatography techniques of Moore and Stein (7, 8). The data obtained from this investigation indicate …

Developing analytical methods to determine physicochemical properties, protein and amino acid composition of African staple foods
… and particle size distribution), protein and amino acid composition of five major African staple foods; namely, maize, sorghum, cassava, corn-soya and teff. Moisture was determined by Karl Fischer titration, and it was found that corn-soya, sorghum, maize, and teff had moisture levels below …

Uncovering the genetic basis of seed amino acid composition in arabidopsis using a multi-omics integrative approach
… diet of humans and livestock. However, protein composition in the seed is low, comprising about 10% of the total composition in the seed. Additionally, protein quality in the seed is poor due to low concentrations of certain essential amino acids (EAA). Since the body is unable to produce EAA, …

Free amino acid composition of flatpea (lathyrus sylvestris L.) as influenced by water-deficit stress, nitrogen fertilization, developmental stage, and rhizobium inoculation
A₂bu composed 20-40% of total free amino acids in flatpea tissues and constituted 2-4% of the tissue dry weight. Higher concentrations of A₂bu were found in the leaves than in the roots. A₂bu concentration in leaves and stems increased slightly with plant age. Higher nitrogen availability increased …

The nutritive value of dried rumen microbiota
… Proximate analyses were conducted and the amino acid composition and B-vitamin content were determined. Protein quality tests were carried out using the Bender-Miller method. The data obtained from the investigation indicated that the protein quality of dried rumen microbiota is comparable …

Virginia-grown Barley for Craft Brewing: Evaluation of Free Amino Nitrogen Content and Malt Sensory Characteristics
… are currently under development. Free amino nitrogen (FAN) is a malt quality parameter that influences beer flavor directly and via yeast metabolism during fermentation. FAN and the individual amino acids making up FAN influence yeast health, beer color development, flavor, and flavor …

COMPARATIVE BIOCHEMICAL AND GENETIC STUDIES OF TESTA DEVELOPMENT IN NORMAL AND HULL-LESS PHENOTYPES OF PUMPKIN (CUCURBITA PEPO L)
… until seeds reached maturity. Structural compositional analysis revealed marked reductions in lignin (78%) and cellulose (50%) in hull-less compared with normal phenotypes; whereas no differences in non-cellulosic polysaccharides were found at 20 days post-anthesis. Between 20 days …

Biosynthesis and identification of enzymes of the cellulase system of Trichoderma reesei
… ions enhanced enzyme production when glutamic acid was present, in which case aryl-β-D-glucosidase, endoglucanase and Avicelase activity were enhanced by 20, 100 and 40 percent, respectively. Under the same conditions asparagine enhanced only ary1-β-D-glucosidase activity. Some of the enzymic …

Impact of Juice Clarification Processes on Chemical Composition of Hard Cider
… juice and cider chemistry, YAN concentration and amino acid composition in juice, polyphenol concentration and composition in juice and cider. Different clarification treatments affected the YAN concentration and amino acid composition differently. Polyphenol concentration in juice was decreased …

An electrophoretic method for the isolation of isohistones from the embryo of the sea urchin Parechinus Angulosus
… to prove me identity of the isolated proteins by amino acid composition and partial sequencing. This serves two purposes, namely, the unequivocal identification of chromosomal proteins characterized only by their electrophoretic mobility as histone variants, and secondly the creation of a …

Freezing Avoidance of Antarctic Fishes: The Role of a Novel Antifreeze Potentiating Protein and the Antifreeze Glycoproteins
AFPP is a 15.5 kDa protein with an unbiased amino acid composition. It was found in all the Antarctic notothenioid fishes examined, at different concentrations. It was most abundant in the shallow water fishes swimming in ice-laden water, but was present at concentrations ten fold less in the …

Characterization of the large diameter fibers in egg case silk : identification of a core fibroin, TuSp1, and localization of fibroin-like molecules, ECPs, from the black widow spider, latrodectus hesperus
… literature. This study used conventional nucleic acid-nucleic acid screening of a eDNA library to isolate a novel gene, named tubuliform spidroin 1 , from the black widow spider Latrodectus hesperus. TuSp 1 was demonstrated to be selectively expressed in the tubuliform gland (the gland suspected …
