What is a zymase?
Zymase substrate is the chemical on which the enzyme zymase acts on. Substrate used could depend on the variety of yeast from which the enzyme is extracted. But, the common substrates are glucose, fructose and maltose.
Can you convert fat to glucose?
yes in fasted states (or when you have used your glycogen stores), glucagon or adrenaline can breakdown stored triglycerides (in adipose tissue) into glycerol and fatty acids. The glycerol goes to the liver when it is involved in gluconeogenesis (synthesis of glucose from non-carb source). This is essentially a reversal of glycolysis: The glycerol molecule is converted to dihydroxyacetone phosphate, which then is converted to fructose 1,6 biphosphate and then after a number of steps, is converted to glucose. I dont think the glycerol molecule is converted to pyruvate, but instead joins in the pathway at the step decribed above.
What is glycosis?
Glycolysis is the metabolic pathway that converts glucose, C6H12O6, into pyruvate, C3H6O3-. The free energy released in this process is used to form the high energy compounds, ATP (adenosine triphosphate) and NADH (reduced nicotinamide adenine dinucleotide)
Which step in glycolysis is the entry point for galactose?
Glycolysis is the break down of glucose in pyruate and release of energy here are the steps in which glycolysis occurGlucose ------> glucsose-6-phosphate -------> fructose-6-phosphate --------> fructose-1,6-bisphosphate --------> glyceraldhyde-3- phosphate and dihydroxyactone phosphate now dihydroxyacetone phosphate isomerize in glyceraldhyde-3- phosphate ----------- 2 glyceraldhyde -3- phosphate ------------> 1,3-bisphosphoglycerate ---------> 3-phosphoglycerate ----------> 2-phosphoglycerate -----------> phosphoenolpyruate ----------- pyruatein these reactions during reaction 1 and 3 ATP are changed into ADP and so these are called energy consuming reactions and in 7 and 10th step 2 ATP are released in both steps so forming 4 ATP and in end giving net gain of 2 ATP. So in glycolysis fructose is consumed after isomerisation and phosphorylating in 2nd step, Fructose also enter directly in glycolysis in some species which use fruit sugar fructose which first convert in Dfructose which is then phorphorylated in fructose-6-phosphate
What is the molecule that enters glycolysis?
short answer: Glycerol can enter the Glycolysis as DHAP. longer answer: The oxidation of triglicerides to fatty acids and glycerol occurs in the cytoplasm. After that, glycerol is phosphorylated and enters glycolysis, while fatty acids are oxidised elsewhere. The oxidation of fatty acids in its common form(beta-oxidation) occurs in mitochondria and in peroxisomes. Glycogen and fatty acids are stored locally. When needed, they are broken down, with the energy used by the cell or exported.
Dihydroxyacetone is converted to glyceraldehyde-3-phosphate by what category of enzyme?
Isomerase
What are the two types of reactions convert glycerol to dihydroxyacetone phosphate?
Phosphorylation and oxidation
What are an aldose ketose pair?
example Dihydroxyacetone (ketone) and D-glyceraldehyde ( aldoste)
How does 3-phosphoglyceraldehyde get changed into dihydroxyacetone phosphate?
This reaction is catalyzed by Triose phosphate isomerase
What is the function of aldolase in regulation of glycolysis?
Aldolase inhibits the reaction F-1-P --> glyceraldehyde + dihydroxyacetone.
What is an aldolase?
An aldolase is an enzyme, present in some tissues, which catalyzes the conversion of phosphates of fructose to those of glyceraldehyde and dihydroxyacetone.
What is the difference in chemical structure between dihydroxyacetone phosphate and glyceraldehyde phosphate?
there's hydrogen in the glyceraldehyde phospate and not in the diydroxyacenton phospate.
What are examples of monosacharide?
glucose, galactose, fructose, ribose (found in RNA), deoxyribose (found in DNA), glyceraldehyde & dihydroxyacetone (the simplest monosaccharides)
4th reaction of glycolysis. reactants, products, enzymes, reversibility?
Fructose 1, 6-bisphosphate to dihydroxyacetone phosphate (DHAP) and Glyceraldehyde-3-Phosphate. Aldolase
What are the list of ingredients in Adonia Bronzing Glow?
ethoxydiglycol dihydroxyacetone troxerutin plus the list of organic ingredients on the web site. these ingredients are listed on the bottle of adonia bronzing glow
Which compound has the empirical formula ch2o?
CH2O is not only the empirical but also the molecular formula for formaldehye. It is also the empirical but not the molecular formula for hydroxyacetaldehyde, acetic acid, methyl formate, 1,3-dihydroxyacetone, and many other compounds.
How safe for your skin is spray tan?
A spray tan is a safe alternative to spending countless hours in the sun ultraviolet rays. The main ingredient in spray tan bottles is dihydroxyacetone, which will tan skin for a few days and is harmless to the skin.
