BACKGROUND Nestle Foods was started by Henri Nestle in the mid eighteenth century‚ in his bid to find an alternative to breast milk for babies whose mothers could not nurse in order to reduce infant mortality. Consequently Nestle’s first customer was a premature infant who could tolerate neither his mother’s milk nor any of the conventional substitutes and had being given up for lost by doctors. The value of the product was recognized after it saved the child’s life. Henri Nestle showed an early

Zellweger syndrome is one of a group of four related diseases called peroxisome biogenesis disorders‚ a group of deadly genetic diseases that claim the lives of children usually before they reach their first birthday. This syndrome is the most common type of peroxisome biogenesis disorder. The disease is caused by defects in any one of 13 genes‚ called PEX genes‚ required for the normal formation and function of peroxisomes. Peroxisomes are cell structures that break down toxic substances and synthesize

The pores are reinforced by platelets of a polysaccharide called callose.

differences in their cell walls. Bacterial cell walls contain a polymer called peptidoglycan. Gram-positive bacteria have more of this polymer than gram-negative bacteria. They are also less complex than gram-negative cell walls‚ missing different polysaccharides‚ lipids‚ and proteins that are found in gram-negative bacteria. Three different stain types are used in the identification process: safranin (pink/red)‚ crystal violet (purple)‚ and Gram iodine. Along with being either gram-positive or gram-negative

the species of Chlorella vulgaris‚ with carbohydrates being 37-55% of its dry weight (Brennan and Owende‚ 2010; Dragone et al.‚ 2011; Illman et al.‚ 2000). The carbohydrates in green algae mainly come from starch in chloroplasts and cellulose/polysaccharides on cell walls (Richmond‚ 2004). The growth of microalgae and the composition of microalgae biomass are known to be greatly dependent on the light supply (type of light source and light intensity) (Ogbonna and Tanaka‚ 2000) medium composition (especially

These beneficial effects can be attributed to the complex mixture of phytochemicals which possess antioxidant‚ antimicrobial‚ anticancer and antiviral activity. The compounds responsible for these activities include phenolic compounds‚ sulphated polysaccharides and organic acids (Liu‚ 2003 and Podsedek‚ 2007) Seaweeds have been used by humans as medicine and food for at least 13‚000 years.

amylase isn’t denatured‚ it should change colors. Amylase is an enzyme. Enzymes are a type of catalyst‚ and speed up chemical reactions within the body. Amylase specifically speeds up the breaking up of starch into maltose. It takes the long polysaccharide‚ and breaks it into smaller disaccharides‚ called maltose. Maltose is faster‚ and easier for a person’s stomach to break down rather than a whole macromolecule. An enzyme is denatured when it is exposed to a pH or temperature that is not right
