13C NMR was used to study the pattern of label incorporation from [2-13C]acetate into trehalose during sporulation in Saccharomyces cerevisiae. A wild-type strain and a strain homozygous for the zwf1 mutation (which affects glucose-6-phosphate dehydrogenase) were used. In the wild-type it was possible to deduce the cycling of glucose 6-phosphate around the hexose monophosphate pathway whilst in...

Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...

This study was conducted to determine the nutritional characteristics of horsemeat and bone meal in comparison with those of beef and pork presented by Dietary Reference Intakes For Koreans. Longissimus muscle and large metacarpal bone samples were collected from 20 fattened Jeju horses. Muscle samples were subjected to proximate analysis, assays for fatty acid profile and minerals, and bone sa...

This experiment determined meat composition and palatability changes resulting from feeding Holstein (HOL) and crossbred beef (XB) steers diets containing corn silage (CS) or alfalfa haylage (AH) (forage type) and soybean meal (SM) or fish meal (FM) (protein source). Fifty-nine steers (30 HOL and 29 XB) were randomly assigned to diet combinations for a 2 x 2 x 2 (breed x forage x protein) facto...

The objectives of this research were to determine total lipid content and corresponding fatty acid profiles in freshwater (n=10) marine fish (n=11) samples commonly consumed Bangladesh. Lipid was extracted by Solid Phase Dispersion method. Saponification esterification carried out the association official analytical chemists (AOAC) reference procedure with some simple modifications. acids analy...

In today's society, the risk of cardiovascular disease is steadily rising. The fatty acid composition three local fermented food condiments (dawadawa, ogiri igbo, and okpei) purchased from different markets in Aba, Nigeria, was studied using gas chromatography mass spectrometry (GCMS) order to look for alternative natural that are absorbed body without having many health implications. profiles ...
