  • An interesting fact regarding sucrose responsiveness is that a specific concentration of sucrose is a necessity for plant growth and survival and at the same time mere increase or decrease from the normal concentration produces adverse results. (scialert.net)
  • Many sugars, fibers, and starches are not easily digested, and humans don't naturally produce enzymes that digest these foods. (bioptimizers.com)
  • Sucrose, the white sugar commonly used in baking, is one of several kinds of sugars, all of which are carbohydrates. (sciencebuddies.org)
  • The petitioner has provided information describing the methods used to develop Simplot Innate® potato events Gen2-W8, Gen2-X17, and Gen2-Y9 and the molecular biology data that characterize the genetic change, which results in reduced levels of free asparagine in tubers, lower levels of reducing sugars (i.e., glucose and fructose) in tubers, reduced expression of polyphenol oxidase 5 enzyme (Ppo5), and expression of the VNT1 protein.

  • The enzyme-catalyzed reaction occurs with greater efficiency and specificity, leading to faster reaction rates. (nawafnet.net)
  • From times till date, studies have well documented the multifarious important functions of carbon source sucrose during plant development from their germination to maturity. (scialert.net)
  • We then prepared a series of test tubes containing different concentrations of sucrose and incubated them at different temperatures. (vumc.org)
  • Why are enzymes for digestion important in avoiding illness? (draxe.com)
  • The results of this study have important implications for the understanding of enzyme function and could potentially be applied in the development of new therapeutic treatments or food processing techniques. (vumc.org)
  • Enzyme structure is important because it determines the enzyme's particular function in the body. (newworldencyclopedia.org)
  • Why are enzymes important to digestion? (bioptimizers.com)
  • Let's learn what enzymes are and why they're so important. (bioptimizers.com)
  • The enzymes are able to hydrolyze N-acetylchitooligosaccharides with a degree of polymerization of two, three, and four. (dtu.dk)
  • It suggested that enzymes responsible for the degradation of CA in the Krebs cycle must be deactivated to accumulate Citric Acid. (microbenotes.com)
  • Experimenting with a plant-based enzyme can help students peer inside the digestion process. (sciencebuddies.org)
  • While all enzymes have a biological role, some enzymes are also used commercially. (newworldencyclopedia.org)
  • Understanding how enzymes work provides insight into many biological processes, and can help us design better treatments for diseases caused by enzyme dysfunction. (nawafnet.net)
