Biochemistry

Some analysis on urine:

- density

- pH

- ketones

- calcium

- phosphate

- vitamin C

- blood cells

- bilirubin

- creatinin

- bacterias

etc.

The enzyme that acts on lactose is called lactase. Lactase breaks down lactose into its component sugars, glucose and galactose, which can then be absorbed by the body. People who are lactose intolerant have low levels of lactase, leading to difficulty digesting lactose.

Dragendorff's reagent typically consists of a mixture of potassium bismuth iodide (KBl3) and bismuth triiodide (BiI3) dissolved in a solution of acetic acid. This reagent is commonly used in chemistry for detecting alkaloids and alkaline earth metals.

Amino acids have two significant characteristics - their -C-C-N- polypeptide-chain monomer and their site for the attachment of a side chain - called the -R group.

While millions of possible -R groups exist, only 20 of these have passed - literally - the biochemical fitness test to be used in Biochemistry [and 2, but only 2, that have special functions].

Yes, humans can produce secondary metabolites. For example, plants produce secondary metabolites such as caffeine and morphine, which can also be produced synthetically or extracted for medical purposes. In the context of human health, the human body produces secondary metabolites through various metabolic processes that can have different effects on the body.

Some top colleges known for their strong science programs include Massachusetts Institute of Technology (MIT), Stanford University, Harvard University, and California Institute of Technology (Caltech). These institutions are recognized for their cutting-edge research opportunities, top faculty, and rigorous academic curriculum in the field of science.

Yes, some pharmacies, including Booths Pharmacy, may offer home drug testing kits for purchase. However, availability may vary depending on the specific location and local regulations. It is best to contact the pharmacy directly or check their website for the most current information on product availability.

An orbit refers to the path an object takes around another object in space, such as a planet around a star. An orbital, on the other hand, refers to the specific mathematical description of the position and movement of an object within that orbit. In essence, an orbit is the physical path, while an orbital is the mathematical model describing it.

When a red blood cell is placed in a hypertonic solution like dextrose, water will move out of the cell by osmosis, causing the cell to shrink and potentially become crenated. This is because the concentration of solutes outside the cell is higher than inside, creating a concentration gradient that drives water out of the cell.

Atoms consist of a nucleus made up of protons and neutrons, surrounded by electrons. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. The arrangement of these particles determines the properties of the atom.

Compound lipids are a type of lipid that consist of a combination of fatty acids, alcohol, and other molecules like phosphate or sugars. They include phospholipids and glycolipids, which are essential components of cell membranes and are involved in various cellular functions.

Foods that are rich in antioxidants include berries (such as blueberries, strawberries, and raspberries), fruits (such as oranges, grapes, and kiwi), vegetables (such as spinach, kale, and broccoli), nuts (such as almonds and walnuts), and seeds (such as chia and flax seeds). Other sources include dark chocolate, green tea, and spices like turmeric and cinnamon.

Dna Pol three is a Dna copying bio-machine - similar more in function than in overall shapes and forms {and cofactors} to Dna Pol I and Dna Pol II - each has It's own special Role [ regarding Dna replication ( synthesis of two new Dna intertwined strands ) ] to perform.

DEPC (diethyl pyrocarbonate) inactivates RNAases by reacting with histidine residues in the active site of the enzyme. This chemical modification disrupts the structure and function of the RNAase, rendering it inactive. DEPC treatment is commonly used to eliminate RNAases in solutions and labware for RNA-related experiments.

As temperature increases, the movement of molecules in a substance also increases. This is because higher temperature provides more energy to the molecules, causing them to move faster and more vigorously. Conversely, lowering the temperature reduces molecular movement.

No, water soluble vitamins are not stored in the body tissues to a significant extent. They are absorbed into the bloodstream and any excess amounts are typically excreted in the urine. This is why it is important to consume them regularly through the diet.

Snottites are formed in caves by much the same process as stalactites, except that snottites are composed of living bacteria, thriving on volcanic sulphur compounds contained in water dripping down over them from above.

Do you mean denatured?

Form is function in an enzyme and if heat or acidity denatures an enzyme the function of the enzyme is compromised. Certain R group bonds being br5oken will denature the enzyme and give it a different conformation.

Get the MR of the NaH2PO4 molecule.

Now use the 1M = (MR)g/L to work out the equation.

The last equation you need is 20mM = (X)g/L

Now you make the units the same, cross multiply and get your answer for X.

Once you do this a few times it becomes second nature.

Random structure in proteins refers to regions that do not adopt a well-defined and stable three-dimensional conformation. These regions are often flexible and can serve various functions, such as facilitating protein-protein interactions or allowing for conformational changes. They can also be involved in signaling pathways or regulatory processes within the cell.

Barfoed's test is used to distinguish monosaccharides that contain a ketone group from those that contain an aldehyde group. It is based on the reaction of monosaccharides with copper acetate in acidic conditions to form a red precipitate. This test is specifically useful in differentiating between monosaccharides like glucose (which has an aldehyde group) and fructose (which has a ketone group).
