what are multimolecular macromolecular and associated colloids?
473624
Multimolecular colloids are formed by the aggregation of a large number of simple molecules, macromolecular colloids consists of macromolecules having size in the colloidal range. On the other hand, associated colloids also called micelles, are generally electrolytes. They exist as ions at low concentration.

Suspensions, colloids and solutions. A suspension is a heterogenous mixture containing large particles that will settle on standing. Sand in water is an example of a suspension. A solution is a homogenous mixture of two or more substances where one substance has dissolved the other.

The separation of macromolecules in an electric field is called electrophoresis. A very common method for separating proteins by electrophoresis uses a discontinuous polyacrylamide gel as a support medium and sodium dodecyl sulfate (SDS) to denature the proteins.

Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.

A macromolecule is a huge molecule made up of smaller subunits called monomers. ... Organic macromolecules are huge molecules that include carbon that are found in living things. They include ones you are probably aware of: proteins, lipids, carbohydrates and nucleic acids.

Proteins: are organic macromolecules that are made up of chains of amino acids. These chains are known as polypeptide chains. ... multiple bonds formed between amino acids in an ever growing polypeptide chain (chains of amino acids, that will eventually form a protein.)

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions.

Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

Dehydration Synthesis Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. ... Biological macromolecules are organic, meaning that they contain carbon.

Water-Soluble Polymer. Water-soluble polymers are substances that dissolve, disperse, or swell in water and, thus, modify the physical properties of aqueous systems in the form of gelation, thickening, or emulsification/stabilization [25].

Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.

All monomers have the capacity to form chemical bonds to at least two other monomer molecules. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.

Explanation: Suspensions and colloids are heterogeneous mixtures. A suspension is identifiable because its particles are large and settle out of the dispersing medium due to the effects of gravity. The dispersed particles of a colloid are intermediate in size between those of a solution and a suspension.

In Lyophobic sol, weak forces of interaction exist between colloidal particles and liquid. ... Unlike Lyophilic colloids, the precipitations of lyophobic colloids do not regain their original state as coagulated mass cannot be dispersed into colloidal form. This shows that lyophobic sols are also irreversible in nature.

A colloid is a homogeneous solution with intermediate particle size between a solution and a suspension. Colloid particles may be seen in a beam of light such as dust in air in a "shaft" of sunlight. Milk, fog, and jello are examples of colloids. In contrast a suspension is a heterogeneous mixture of larger particles.
