一、概述 1、概念:构成生物体的元素,已知有五十多种,除去C、H、O、N四种构成水分和有机物质的元素外,其它元素统称为矿物质。 2、功能 (1)是构成生物体的组成部分

Modified atmosphere packaged (MAP )prepared fresh produce provides substrates and environmental conditions conducive to the survival and growth of microorganisms. Minimal processing treatments such as peeling and slicing disrupt surface tissues, expose cytoplasm and provide a potentially richer source of nutrients than intact produce(Brackett 1994; Barry-Ryan and O'Beirne, 1998, 2000). This, combined with high Aw and either close to neutral (vegetables) or low acid (many fruits) tissue pH, facilitate microbial growth (Beuchat, 1996)

An overview on D-glucose metabolism The major fuel of most organisms,4'o=-2840kJ/mole if completely oxidized to CO, and H, via the glycolysis pathway, citric acid cycle and oxidative phosphorylation (generating ATP). Can also be oxidized to make NADPH and ribose-5-P via the pentose phosphate pathway

In addition to the equations of linear impulse and momentum considered in the previous lecture, there is a parallel set of equations that relate the angular impulse and momentum. Angular Momentum We consider a particle of mass, m, with velocity v, moving under the influence of a force F. The angular momentum about point O is defined as the \moment\ of the particle's linear
