Pantothenic Acid and Vitamin C

Overview
Pantothenic acid is a vitamin, also known as vitamin B5. It is widely found in both plants and animals including meat, vegetables, cereal grains, legumes, eggs, and milk. Pantothenic acid is important for our bodies to properly use carbohydrates, proteins, and lipids and for healthy skin.

Uses
1. Pantothenic acid deficiency.
2. Skin reactions from radiation therapy: Applying dexpanthenol to affected area.
3. Attention deficit-hyperactivity disorder (ADHD).
4. Other Uses:
Dry eyes,Eye trauma, Osteoarthritis, Recovery after surgery, Rheumatoid arthritis, Nasal dryness, Sinus infection, Skin irritation, Sprains, Alcoholism, Allergies, Hair loss, Asthma, Heart problems, Carpal tunnel syndrome, Lung disorders, Colitis, Eye infections (conjunctivitis), Convulsions, Kidney disorders, Dandruff, Depression, Diabetic problems, Enhancing immune function, Headache, Hyperactivity, Low blood pressure, Inability to sleep (insomnia), Irritability, Multiple sclerosis, Muscular dystrophy, Muscle cramps, etc.

Side Effects and Safety:
Pantothenic acid is LIKELY SAFE for most people when taken by mouth in appropriate amounts. The recommended amount for adults is 5 mg per day. Even larger amounts (up to 10 grams) seem to be safe for some people. But taking larger amounts increases the chance of having side effects such as diarrhea.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Pantothenic acid is LIKELY SAFE when taken by mouth in recommended amounts of 6 mg per day during pregnancy and 7 mg per day during breast-feeding. However, it is not known if taking more than this amount is safe. Avoid using larger amounts of pantothenic acid.
Children: Dexpanthenol, a derivative of pantothenic acid, is POSSIBLY SAFE for children when applied to the skin.
Hemophila: Do not take dexpanthenol, a derivative of pantothenic acid, if you have hemophila. It might increase the risk of bleeding.
Stomach blockage: Do not receive injections of dexpanthenol, a derivative of pantothenic acid, if you have a gastrointestinal blockage.
Ulcerative colitis: Use enemas containing dexpanthenol, a derivative of pantothenic acid, cautiously if you have ulcerative colitis.

Dosing:
As a dietary supplement: 5-10 mg of pantothenic acid (vitamin B5).
Recommended daily intakes for pantothenic acid (vitamin B5) are as follows: Infants 0-6 months, 1.7 mg; infants 7-12 months, 1.8 mg; children 1-3 years, 2 mg; children 4-8 years, 3 mg; children 9-13 years, 4 mg; men and women 14 years and older, 5 mg; pregnant women, 6 mg; and breastfeeding women, 7 mg.

Vitamin B6 (Pyridoxine)
Pyridoxine is a vitamin. It can be found in certain foods such as cereals, beans, vegetables, liver, meat, and eggs. It can also be made in a laboratory. Pyridoxine is required for the proper function of sugars, fats, and proteins in the body. It is also required for the proper growth and development of the brain, nerves, skin, and many other parts of the body.

Uses:

Vitamin B12
Vitamin B-12 is a crucial B vitamin. It is needed for nerve tissue health, brain function, and the production of red blood cells. Cobalamin is another name for vitamin B-12.

Fast facts on vitamin B-12:
1. Vitamin B-12 is important for brain function the synthesis of red blood cells.
2. Deficiency of vitamin B-12 can lead to neurological difficulties and anemia.
3. People over the age of 14 should consume more than 2.4 micrograms (mcg) of vitamin B-12 daily.
4. Vitamin B-12 is naturally available in meats, but people who do not eat meat, such as vegans, can obtain vitamin B-12 in supplement form.

Foods:
Vitamin B-12 can be found naturally in animal products, such as fish, meat, eggs, and dairy products. It does not typically occur in plant foods.
Good dietary sources of vitamin B-12 include:
1. beef
2. pork
3. ham
4. poultry
5. lamb
6. fish, especially haddock and tuna
dairy products, such as milk, cheese, and yogurt
some nutritional yeast products
7. eggs
Some types of soya milk and breakfast cereals are fortified with vitamin B-12.

Benefits:
Vitamin B-12 is crucial to the normal function of the brain and the nervous system. It is also involved in the formation of red blood cells and helps to create and regulate DNA.
The metabolism of every cell in the body depends on vitamin B-12, as it plays a part in the synthesis of fatty acids and energy production. Vitamin B-12 enables the release of energy by helping the human body absorb folic acid.

Deficiency symptoms:
1. Vitamin B-12 deficiency occurs when the body does not receive enough vitamin B-12.
2. It can result in irreversible and potentially severe damage, especially to the nervous system and brain.
3. Thought processes
Vitamin B-12 is important for brain function, and neurological symptoms occur if the body does not have enough.
4. Even slightly lower-than-normal levels of vitamin B-12 can trigger deficiency symptoms, such as depression, confusion, memory problems, and fatigue.
5. Other symptoms of vitamin B-12 deficiency include constipation, loss of appetite, and weight loss.

WELDING

Welding is a fabrication or sculpturalprocess that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that is usually stronger than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Processes Arc These processes use a welding power supply to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point. They can use either direct(DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is sometimes prot

What is Hurdle Technology?

Hurdle technology is a method of ensuring that pathogens in food products can be eliminated or controlled. This means the food products will be safe for consumption, and their shelf life will be extended. Hurdle technology usually works by combining more than one approach. These approaches can be thought of as "hurdles" the pathogen has to overcome if it is to remain active in the food. The right combination of hurdles can ensure all pathogens are eliminated or rendered harmless in the final product. Hurdle technology has been defined by Leistner (2000) as an intelligent combination of hurdles which secures the microbial safety and stability as well as the organoleptic and nutritional quality and the economic viability of food products. The organoleptic quality of the food refers to its sensory properties, that is its look, taste, smell and texture. Examples of hurdles in a food system are high temperature during processing, low temperature during storage, increasing the

Assignment on Lipoprotein

Download the Document:  Lipoprotein Introduction: Lipoproteins are aggregates, consisting of proteins, polar lipids and triacylglycerols; which are water soluble and can be separated into protein and lipid moieties by an extraction procedure using suitable solvents. This indicates that only non-covalent types of bonds are involved in the formation of lipoproteins. The aggregates are primarily stabilized by hydrophobic interactions between the apolar side chains of hydrophobic regions of the protein and the acyl residues of the lipid. In addition, there is a contribution to stability by ionic forces between charged amino acid residues and charges carried by the phosphatides. Hydrogen bonds play a small role in binding lipids molecules as there are only few sites available for such linkages. In wheat flour, the lipoprotein complex consists of prolamine and glutelin attached to glycolipids by hydrogen bonds and hydrophobic forces. Thus, lipoproteins are held together only by non-covalent
