S TUDIES of the chemical nature of prothrombin have indicated a glycoprotein structure.2 Data obtained on purified bovine prothrombin have shown the reducing sugar content to be approximately 5 per cent, based on a reference standard of galactose and mannose.35 Laki et al.5 reported a value of 6.5 per cent in terms of glucose, and 1.6 to 1.7 per cent hexosamine. Alexander6 and colleagues observ...

Cell walls were prepared mechanically from both hyphae and conidia of Penicillium chrysogenum. The major carbohydrate components of cell wall hydrolysates were glucose, galactose and glucosamine, with lesser amounts of mannose and rhamnose. The conidia were richer in galactose and the hyphae contained more glucosamine. The distribution of the monomers in acidsoluble and alkali-soluble fractions...

By E. E. WOOD5IDE AND \V. KOCHOLATY T HE LACK of information on the polysaccharides and their corresponding monomers in human and bovine platelets has prompted this comparative study on the total bound monosaccharide units and their derivatives in these formed elements of blood. The determination of the monosaccharides in various chemically fractionated components ( an acid mucopolysaccharide f...

a total of 65 pollen types were identified from two years atmospheric pollen survey in the environmental conditions of south assam. out of them, eight pollen types viz., acacia auriculiformis, amaranthus spinosus, cassia alata, cleome gynandra, cocos nucifera, imperata cylindrica, ricinus communis and trewia nudiflora, were selected for biochemical studies on the basis of their dominance in the...

Five varieties of cowpea (Vigna unguiculata) were analysed for their proximate composition, major mineral elements and carbohydrate fractions. Values crude protein ranged from 25.80% to 28.95% while the ether extract, fibre, total ash had following values: 1.83 - 2.37%, 3.06 4.48%, 5.80 7.10% 50.46 55.76% respectively. The average values phosphorus, calcium, magnesium, potassium sodium 0.400%, ...

AIM To evaluate some forage feeds of ruminants in terms of their carbohydrate (CHO) and protein fractions using Cornell Net Carbohydrate and Protein System (CNCPS). MATERIALS AND METHODS Eleven ruminant feeds (six green fodders - maize, oat, sorghum, bajra, cowpea, berseem and five range herbages - para grass, guinea grass, hedge lucerne, setaria grass and hybrid napier) were selected for thi...

1. The effects of dietary energy level and dietary energy source on protein utilization by plaice (Pleuronectes platessa) were examined by giving diets containing 400 g crude protein/kg to nine groups of fish. Five of these diets contained only lipid as a source of energy (in addition to protein) and their energy contents were varied by increasing the lipid level in a step-wise manner from 56 t...
