What is the antioxidant system?

Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals and chain reactions that may damage the cells of organisms. Antioxidants such as thiols or ascorbic acid (vitamin C) may act to inhibit these reactions.

Which of the following is considered an essential nutrient?

Examples of essential nutrients include: proteins, fats, carbohydrates, vitamins, minerals, and water (aka the six classes of nutrients.) Nonessential nutrients are nutrients that can be made by the body. Examples include dietary fiber and non-essential amino acids.

What are the 6 nutrients and examples?

There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.

Which is a common use of minerals?

It is used in glass and ceramic industries; pottery, porcelain and enamelware; soaps; bond for abrasive wheels; cement; glues; fertilizer; and tarred roofing materials and as a sizing, or filler, in textiles and paper applications.

What are the two main ways that minerals are classified?

Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).

What are 3 ways in which minerals form?

The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which …

How do you classify minerals?

Using Characteristics of Minerals to Identify Them. Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

How do you categorize minerals?

Minerals are classified on the basis of their chemical composition, which is expressed in their physical properties. This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.

What properties can be used to identify minerals?

The physical properties of minerals are determined by the atomic structure and crystal chemistry of the minerals. The most common physical properties are crystal form, color, hardness, cleavage, and specific gravity. One of the best ways to identify a mineral is by examining its crystal form (external shape).

How can we use properties to identify unknown minerals?

You can identify a mineral by its appearance and other properties. The color and luster describe the appearance of a mineral, and streak describes the color of the powdered mineral. Each mineral has a characteristic density. Mohs Hardness Scale is used to compare the hardness of minerals.

Which properties are not commonly used to identify minerals?

Answer: Mass and size are properties not commonly used to identify minerals.

Which is not a property used to identify minerals?

Explanation: Color is rarely very useful for identifying a mineral.

What is the property of minerals that reflects light?
