What are the major groups of inorganic compounds?
INORGANIC COMPOUNDS water-is the most abundant molecule in all organisms. -it also posses unique properties that make it highly essential in biological systems.. PROPERTIES OF WATER # ability to dissolve substances. water is a universal solvent. it can dissolve almost anything. # HYDROGEN-bonding ability. water molecules have an extensive network of hydrogen bonds. this network results in high heat capacity, high heat of evaporation, and high heat of fusion of water. acids-comes from the Latin word acidus meaning 'sour'. -may be classified as strong and weak. PROPERTIES IF ACIDS # they have a sour taste. # they turn blue litmus paper into red. # they react w/ active metals to form hydrogen gas. bases-have poperties that contrast thse of acids. bases are substances that yield hydroxide ions (OH-) in a water solution, while acids are substances that release hydrogen ions(H+). PROPERTIES OF BASES # they taste bitter and feel slippery. # they turn red litmus paper to blue. # like acids, they are also corrosive to the skin. salts
What does potassium chlorate yield?
Potassium chlorate, when heated strongly, decomposes into potassium chloride and oxygen gas. This decomposition reaction is often used to produce oxygen gas in chemistry experiments or industrial processes.
When an acid reacts with a base what compounds are formed?
salt & water
Insoluble sulfide compounds are generally black in color Which of the following combinations could yield a black precipitate?
Li2S + KCl and K2S + Sn(NO3)4 will yield a black precipitate
What is the chemical formula for potassium oxide plus nitric acid?
Potassium hydroxide and nitric acid will yield potassium nitrate and water. KOH + HNO3 --> H2O + KNO3
What is the products of the saponification of tripalmitin?
Tripalmitin is a 16 carbon saturated fatty acid. Saponification is a reaction involving a strong base (ex: NaOH) and a fatty acid. The reaction yields a glycerol and 3 fatty acid salts. Therefore the reaction products are: glycerol: CH2(OH)--CH(OH)--CH2(OH) + 3 fatty acid salts: CH3--(CH2)14--COO(-) Na(+) + 3H2O Above is actually a summary of what is in reality a 2-step reaction: the fatty acid reacts with H2O first to yield a glycerol and 3 fatty acids; the fatty acids subsequently reacts with the alkaline (base) (NaOH) to yield 3 fatty acid salts and H2O
When Fatty acids are hydrolyzed they yield what?
transported across fat cell membranes by fatty acid binding proteins
What enzyme in the stomach acts on preemulsified fat to yield free fatty acids to glycerol?
gastric lipase
What enzyme in the stomach acts on preemulsified fat to yield free fatty acids and glycerol?
Gastric lipase
What does the hydrolysis of lipid molecules yield?
Hydrolysis of lipid molecules yields fatty acids and glycerol. This process breaks down lipids into their individual components, which can then be used by the body for energy production or to build new molecules.
Why does hydrolysis of lipid molecules yield fatty acids and glycerol?
The hydrolysis of lipid molecules breaks the ester bonds that hold the fatty acids to the glycerol molecule. This process involves the addition of water molecules to the bonds, leading to the separation of fatty acids and glycerol as individual components.
Why is the energy yield lower when a unsaturated fatty acid has undergone beta oxidation?
Because in the first reaction of beta oxidation of unsaturated fatty acids a trans double bound is formed from cis-double bound by an izomerase without formation of FADH2. Thus the first oxidation step is skiped and hence less energy yield.
How will you prepare propane from sodium salt of fatty acids?
To prepare propane from the sodium salt of fatty acids, the process of saponification is typically used. Saponification involves reacting the sodium salt of fatty acids (soap) with a strong acid to split off the fatty acid, which can then be further processed to yield propane. The propane is obtained by decarboxylation of the fatty acid through a series of chemical reactions.
What makes a fatty acid produce more ATP?
Fatty acids produce more ATP compared to glucose due to their higher energy density. When metabolized in the mitochondria through beta-oxidation, fatty acids yield more acetyl-CoA molecules per carbon atom, leading to increased ATP production through the citric acid cycle and oxidative phosphorylation. This higher ATP yield makes fatty acids a more efficient energy source for the body, especially during prolonged periods of low-intensity exercise or fasting.
How is it that other nutrients can be metabolized to yield ATP?
Apart from glucose you have Fatty acids, Glycerol and Proteins, which enters the Creb's cycle to yeald ATP, after break down.
How are fatty acids used for energy?
1) Biochemistry Oxidation of fatty acids results in the generation of the energy carrying molecules NADH and FADH2 used by the bodies' oxidative phosphorylation to yield molecules of ATP. ATP can be saved up briefly and is used by much of your bodies chemistry to "power" chemical reactions or, in other words, do work. In this way ATP can be thought of as the bodies "currency" for energy. So, this production of ATP is the biochemical explanation for how fatty acids are used for energy. 2) Biofuels Fatty Acids can be combined with a catalyst (usually lye, I think) and methanol or ethanol (simple alcohols) to produce biodiesel, the fuel which the diesel engine was originally designed to be fueled by. Interesting note: bio-diesel production has the by-product of glycerin which is sometimes used in detergent and soap mixtures, and soaps are the salts of fatty acids.

Can unused fats be turned into carbohydrates?
Not technically. Enzymes split the triglyceride molecules into glycerol and three fatty acids. Glycerol is then converted into PGAL, an intermediate in glycolysis in the cytoplasm. The fatty acids are converted into Acetyl Coenzyme (Acetyl CoA), and enter the Krebs cycle in the mitochondria. The ATP yield is roughly 32-38 molecules of ATP.
