Plastics and Polymers

Lipids are unlike the other macromolecules in that they do not have monomers per se. They are made up of glycerol and fatty acids, but it's not like DNA which is made up of nucleotides or proteins that are made up of amino acids. However, they are still considered macromolecules as lipids are a large category of important molecules in the human body.

Plastic itself is not inherently antibacterial. However, some plastics can be engineered or treated with antibacterial agents to inhibit the growth of bacteria on their surface.

A condensation reaction involves the loss of a small molecule like water or alcohol. If a molecule has only one functional group available for reaction, there is no additional site for the loss of a molecule, which is necessary to form a polymer chain. Hence, a molecule with only one functional group cannot undergo condensation polymerization to form a polymer.

All the polymer can not be made electrically conductive unless there are sufficient charge carriers available within the polymer itself. These charge carriers are responsible for conduction of electrical current. There is hardly a difference between a conducting polymer and conjugated polymer. The conjugated polymers have alternate single and double bond. Moreover, all conjugated polymers are conducting polymers. Their conductivity is increased on adding a suitable impurity in order to make free charge carriers.

Plastic can be engraved by a number of ways. If you're looking to do it yourself, then a steady hand and a dremel tool will work, but if you're looking for a more professional result with intricate details then you may want to look at either a laser engraver or a rotary engraver. A laser engraver can engrave any plastic that does not contain PVC (it is toxic when it goes under the laser), but a laser engraver can provide find details that the rotary engraver can not. A rotary engraver can engrave just about any plastic but may be limited to the amount of detail required in the engraving.

A polyethylene bag with a high-density structure is typically the least porous plastic bag option. These bags are less permeable to air, water, and other gases compared to low-density polyethylene bags, making them a more ideal choice for packaging items that require minimal exposure to outside elements.

A plastic shank is a support structure or piece used in the construction of certain types of footwear, like shoes or boots. It is typically inserted between the insole and outsole to provide rigidity and support to the shoe, especially in the arch area. Plastic shanks help improve the stability and structure of the shoe, making them more comfortable to wear.

Plastic wrap will melt or possibly catch fire if placed in an oven, as it is not safe for high temperatures. This can release harmful chemicals and fumes into the air, and is a fire hazard. It is best to avoid putting plastic wrap in the oven.

The tendency of a polymer to crystallize decreases with increasing molecular weight because as

the chains become longer it is more difficult for all regions along adjacent chains to align so as to produce

the ordered atomic array.

Polymers rely on carbon as the main element for their structure. Carbon atoms are linked together in long chains to form the backbone of polymer molecules. Other elements such as hydrogen, oxygen, nitrogen, and occasionally other elements like sulfur or silicon can also be present in polymer structures, but carbon is essential for their formation.

Plastics are typically good electrical insulators, meaning they do not conduct electricity well. This is due to their molecular structure which restricts the flow of electrons. However, some plastics can become conductive when certain additives or fillers are included in their composition.

the coefficient of restitution for the perfectly plastic body is zero(0).

the coefficient of restitution for the perfectly elastic body is one(1).

When two polymers of amino acids join together, it is a dehydration synthesis reaction. Just like all other dehydration syntheses, water is released due to the formation of a peptide bond.

DNA polymerase catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed. This enzyme helps to link the 3' hydroxyl group of the growing DNA chain to the 5' phosphate group of the incoming nucleotide.

The (plastic) or rubber or whatever is covering a wire acts as an insulator to keep the metal parts (the conductor) of the wire from touching each other (which would cause a short circuit and possibly a fire) and from touching you when energized (which could cause a nasty shock.)

DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called nucleobases .

In general, paper bags can support more weight than plastic bags due to their stronger structure and ability to hold heavier items. This difference is mainly because paper bags are made from a renewable and biodegradable material that is typically thicker and more durable than single-use plastic bags.

Dental polymer is used along with a monomer it is a catalysts and a base. example- acrylic is used to reline dentures to make them fit better, which is a polymer and monomer.

Sodium tetraborate (borax) is commonly used to create polymer balls, but you can also use other borate-based substances like boric acid. Additionally, you can experiment with substitutes like liquid starch or contact lens solution mixed with baking soda to achieve a similar polymer ball effect.

I think it means, do you feel like nobody needs you so you drift away and get forgotten?

DNA is the polymer responsible for inheritance as it contains the genetic information passed down from one generation to the next. DNA molecules encode for the traits and characteristics that are inherited from parents to offspring.

Plastic has become a part of our life. If we ban the use of it, it may cause a hindrance in our daily life. For eg. If you remove plastic bag you can use paper or fiber bags.. But what you will do in case of electrical appliances like T.V. It cant be of paper it may be of metal but that may increase the risk of getting electric shock... So its use can be reduced but cant banned, it can be banned but only its bag.

Monomers are small molecules that can join together to form polymers through chemical reactions called polymerization. In organic compounds, monomers typically include molecules such as amino acids, nucleotides, and monosaccharides. Polymers are large molecules made up of repeating units of these monomers, such as proteins, DNA, and carbohydrates.

Yes, nucleotides form polymers called nucleic acids. Nucleic acids are long chains of nucleotides that are essential in storing and transmitting genetic information. DNA and RNA are examples of nucleic acids formed by nucleotide polymers.
