What Are Essential Amino Acids?

A mino acids are small molecules, or subunits, that link together in various combinations to make up big, complicated proteins. As such, amino acids are commonly referred to as “the building blocks” of proteins.

Q: How many amino acids are used in our body?

A: There are 20 amino acids that are used within our body to synthesize or produce our unique human proteins.  Of these amino acids,  9 are termed essential, meaning our bodies require them to live but cannot make them. Therefore, the essential amino acids must come from the food we eat, whether from plant or animal sources.

The essential amino acids include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

What Is Zinc?

Z inc is an essential trace mineral that is involved in numerous aspects of cellular metabolism, being essential for activation of almost 200 enzymes that have vital roles in the body.

Q: What happens when enzymes do not get activated?

A: When enzymes do not get activated, they cannot perform their necessary functions which, in turn, damages health.

Zinc promotes healthy skin, hair, immunity, fertility, and growth.

A daily intake of zinc is required to maintain a steady state because the body has no specialized zinc storage system.¹ Functions are more fully described below.

What Is Selenium?

S elenium is a mineral that is required by the body  in trace amounts for a healthy immune system, normal thyroid function, and antioxidant protection.

Selenium is absolutely required in the production of at least 30 selenoproteins in the body. First, selenium is joined to the amino acids cysteine as selenocysteine and to methionine as selenomethionine before being used as components for selenoproteins. Many selenoproteins are important antioxidant enzymes such as glutathione peroxidase.

Q: How does glutathione peroxidase work?

A: Glutathione peroxidase activity helps the recycling of vitamins C and E in optimizing the performance of the antioxidant system. The antioxidant properties of selenoproteins help prevent cellular damage from free radicals. Free radicals are natural by-products of oxygen metabolism that may contribute to the development of chronic diseases such as cancer and heart disease.

In the immune system, selenium stimulates immune properties of lymphocytes (white blood cells) by contributing to higher natural killer lymphocyte activity. Natural killer lymphocytes have the ability to destroy cancer cells and bacterial and viral agents.

Other selenoproteins help protect the thyroid gland from anti-oxidants and regulate thyroid function. Specifically, selenium plays an integral role in thyroid gland metabolism.¹ Functions are more fully described below.

According to the Food and Agriculture Organization, United Nations, approximately 30 percent of tissue selenium is contained in the liver, 15 percent in kidney, 30 percent in muscle, and 10 percent in blood plasma.

What Is Potassium?

P otassium is a mineral that is crucial for life being essential for every cell, especially nerve and muscle function.

Most potassium is intracellular, meaning it is found within cells while sodium, its opposing mineral (both electrolytes), is found in the fluid surrounding cells.

In muscle contraction, exchange of potassium and sodium takes place so that potassium moves out of muscle cells and sodium moves into them.

With muscle relaxation, potassium moves back into the cells and sodium moves out. Functions are described below.

Importantly, a recent study investigating the association between the metabolic syndrome and potassium intake in the general population found a significant inverse association between potassium intake and metabolic syndrome in adults. That is, the lower the potassium intake, the greater the odds of developing metabolic syndrome. After adjusting for various lifestyle and dietary confounders, subjects in the highest quartile of potassium intake had 39% lower odds for metabolic syndrome compared to those in the lowest quartile. This association was consistent for both sexes. Among the components of metabolic syndrome, potassium intake was inversely related to abdominal obesity and fasting hyperglycemia in multivariate analysis.¹

What Is Phosphorus?

P hosphorus is an essential mineral present in every cell of the body mostly in the form of phosphate.

About 85% of phosphorus is present in bone making up a major component of bone formation. As a component of calcium phosphate, phosphorus constitutes 45% of skeletal bone weight while calcium constitutes 40% to support the body.¹.

Phosphorus is required for normal tooth development. Inadequate phosphorus in early childhood development makes for defective tooth enamel in permanent teeth.

Phosphorus is crucial for the production of ATP (adenosine triphosphate), a molecule within cells that the body uses to store energy, and is required for production of phosphocreatine to power muscles.  Functions are more fully described below.

One gram of protein in food provides approximately 15 mg of phosphorus. In an adult, the body content of phosphorus ia about 700 grams.

What Is Magnesium?

M agnesium is an essential mineral predominantly found in the body within cells, where it is vital for their functions.

Here is a summary of what magnesium does in our body:

1. Co-factor for over 300 enzymes involved in the metabolism of food components and synthesis of many compounds.
2. Required for nerve transmission.
3. Required for muscle activity (acts to relax muscles in opposition to calcium which acts to contract).
4. Acts to maintain heart rhythm.
5. Required for membrane transport and interactions.
6. Required for glucose metabolism and energy production within cells.
7. Component of bone mineralization and tooth formation.
8. Plays a key role in calcium and phosphorus metabolism and management by parathyroid hormone.
9. Maintains the structural and functional integrity of vital eye tissues such as lens.¹

Only 1% of magnesium is found in blood, but the body must keep blood levels of magnesium constant.

What Is Iron?

I ron is an essential mineral that is required for normal body function.

Almost two-thirds of iron in the body is found in hemoglobin, the protein in red blood cells that carries oxygen to tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions.

Iron is also found in proteins that store iron for future needs and that transport iron in blood.

Q: How are iron stores regulated?

A:Iron stores are regulated by intestinal iron absorption.¹That is, whenever iron is needed, more iron is absorbed than when iron is sufficient. This mechanism prevents excess iron in the body which is harmful.

In the brain, iron is necessary to ensure oxygenation and to produce energy in the cerebral parenchyma (via cytochrome oxid. ase), and for the synthesis of neurotransmitters and myelin.

Iron concentrations in the umbilical artery are critical during the development of the fetus, and in relation with the IQ in the child.²

What Is Chromium?

C hromium is a mineral that the body absolutely requires in trace amounts for normal metabolism, meaning the physical and chemical processes by which energy is produced and used.

Chromium is especially involved in the use of glucose sugar and lipids such as cholesterol and the effectiveness of insulin hormone.

Q: How is chromium involved in the use of glucose?

A: Very small amounts of chromium are required to enable insulin to move glucose from the bloodstream into cells for use as energy.

Insulin is a hormone that controls the use and storage of glucose in two ways: 1) lowers a rise of glucose in blood after meals by moving it out of the bloodstream into body cells, especially muscle cells and 2) limits the release of glucose from the liver between meals. Insulin is produced by beta cells on the surface of the pancreas.

To date, the molecular mechanism by which chromium affects glucose and lipid metabolism is still unclear.¹

What Is Calcium?

C alcium is the most abundant mineral in the body, with 99% residing in teeth and bones where it constitutes 40% of skeletal bone weight along with 45% phosphorus.

As a component of hard tissues, calcium fulfills a structural role to maintain body size and acts as attachments for musculoskeletal tissues.

Q: What does the non-skeleton calcium do in the body?

A: The remaining 1% of calcium is present in blood and soft tissues. Calcium levels in the blood are maintained within very strict limits by dietary intake, hormonal regulation and a rapidly exchangeable pool in bone tissue. The many important functions are described below.

What Is Linoleic Acid?

L inoleic acid is an essential omega-6 fatty acid that comes from plant sources. Essential means the body must have it to maintain health and life sustaining functions. Omega-6 fatty acids are polyunsaturated.

Among its many vital roles in the body, linoleic acid composition of intestinal membranes is important for epithelial cell function and disturbances may contribute to the pathophysiology of celiac disease.¹

Q: What are epithelial cells?

A: Epithelial cells make up the surface mucosa of the digestive tract and also the respiratory tract, urinary tract and genital tract.

Linoleic acid is an important building material for the eicosanoids, a large group of highly bioactive hormone-like substances including prostaglandins, leukotrienes, and thromboxanes that are involved in blood clotting, inflammation, and vasoconstriction.²
