What is the GDA of vitamins and minerals?

The GDA (Guideline Daily Amount) for vitamins and minerals can vary depending on age, gender, and other factors. It is important to check with a healthcare provider or nutritionist to determine the specific recommended daily intake for your individual needs.

Can smoke be turned into a liquid?

Yes, smoke can be condensed into a liquid form through a process called condensation. This involves cooling the smoke to a temperature where it transforms from a gas to a liquid.

What is the principle behind salkowski test?

a test for cholesterol. When concentrated sulfuric acid is added to a chloroform solution of cholesterol, the chloroform layer shows a red to blue colour and the acid layer shows a green fluorescence. [After Ernst Leopold Salkowski (1844 - 1923), German physiological chemist.]

How do you break down a polysaccharide?

Polysaccharides can be broken down by enzymes specific to the type of bonds present in the molecule. For example, amylase breaks down starch into simpler sugars like glucose. Polysaccharides can also be broken down through hydrolysis reactions with acids or bases.

What are the properties of urea formaldehyde?

As a polymer the properties are: Urea formaldehyde is rigid, strong, brittle and has a high surface hardness, which makes it scratch resistant. It is also heat resistant, as it is a thermosetting polymer. It has a very low water absorption rate, and it is a good electrical insulator. UF has a high tensile strength and it is opaque.

this is all that i could find, and it is only for AS level resistant materials.

Water and certain vitamins are absorbed here from the undigested food?

The small intestine is responsible for absorbing water and vitamins from undigested food through its large surface area and specialized cells such as villi and microvilli. Villi increase the absorptive surface area, while microvilli on the surface of enterocytes further enhance nutrient absorption by increasing surface area and facilitating transport.

What is Alanine?

Alanine is a non-essential amino acid that plays a key role in the regulation of blood sugar levels and energy production in muscle cells. It is commonly found in protein-rich foods such as meat, poultry, and dairy products.

What happens when you lack vitamin d?

B1 defeciency is related to a disease called beriberi. It can include irregular heartbeat, edema (puffy) in the extremities, paralysis, and other nervous system ailments.

It gets its name from people in Asia who only ate white rice. They ended up with this problem, wheras people who ate brown rice did not.

What are the qualifications required to become a biochemistry lecturer?

To become a biochemistry lecturer, you typically need a Ph.D. in Biochemistry or a related field, along with teaching experience. Strong communication skills and a passion for teaching are also important. Additionally, research experience and publications in the field of biochemistry can enhance your qualifications.

What is inside the atom?

Electrons, protons, and neutrons are inside the atom.

Where each particle is located

Electrons are located in the electron cloud (surrounds the nucleus) , but CAN come from the nucleus in transmutation, when a proton splits in two.

Protons and neutrons are found in the nucleus, which is the center of the atom.

Protons are positively charged.

Neutrons are neutrally charged.

Electrons are negatively charged.

I'm not going to get into it, but there are also "alpha particles" and "beta particles."

There are many things to discuss about inside the atoms, these are the basics.

Mezon Hypron Quarks Pozetron Nitrenos Takyons .... and many others and more yet to be discovered

What type of nutrient is digested by pepsin in the stomach?

Pepsin in important for the digestion of protein. The enzyme is created in the stomach and breaks down the collagen protein.

What is the molar extinction coefficient for glucose at 510 nm?

I am not some one of this background and so please correct me if I am wrong.

I think molar extinction coefficient will be very less and according to molecular structure of any molecule (bond vibration etc..,) only some wavelengths will have reasonable absorption and for glucose those wavelenghts are 1550-1850 nm; 6450-5400 cm(-1) (first overtone) 2000-2500 nm; 4000-5000 cm(-1) (combination). These are the spectral windows in which glucose has significant absorption.

How do you perform Heller's ring test?

put 5mL of conc. HNO3 in a test tube, incline the tube and allow 2% albumin solution to flow down the side of the tube slowly... watch the interface of both liquids... ^^

Nearly every chemical reaction in the body is activated - assisted - and controlled by?

enzymes. Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. They are specific to particular substrates and play a crucial role in metabolism and other biochemical processes in the body.

Do vitamin b shots hurt a week later?

Pain or discomfort a week later from a vitamin B shot is not typical. If you are experiencing pain or discomfort at the injection site more than a few days after the shot, it's a good idea to consult with a healthcare provider to rule out any possible complications or concerns.

How many cells does a zygote have?

A zygote has one cell, which is formed when a sperm fertilizes an egg during fertilization. The zygote contains the genetic material from both the father and mother and is the first cell of a new organism.

What is a description of the different osmotic solutions?

Hypotonic solutions have a lower solute concentration than the cell, causing water to move into the cell. In hypertonic solutions, the solute concentration is higher outside the cell, leading to water moving out of the cell. Isotonic solutions have equal solute concentration inside and outside the cell, resulting in no net movement of water.
