fomenos

Polymers are macromolecules composed of similar monomers joint through chemical bonds. <em>Lipids </em><em>are not composed of similar </em><em>basic units</em><em>, so they are </em><em>not</em><em> considered to be </em><em>polymers</em><em>. There is no formation of a polymer lipid.  </em>

------------------------------------------------

<em>Together with proteins, carbohydrates, and nucleic acids, </em><em>lipids</em><em> are essential </em><em>components</em><em> of </em><em>biological structures</em><em> and are part of the </em><em>biomolecules </em><em>group. </em>

When talking about <u>polymers</u>, we are referring to molecules composed of multiple similar units, the monomers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer. These units do not need to be identical.

According to the polymer definition, <em>polysaccharides, proteins, and nucleic acids are polymers</em>.<em> </em><u><em>Lipids</em></u><u><em> are </em></u><u><em>not polymers</em></u> because they are not composed of a repeated sequence of basic units.

Lipids are individual medium-sized molecules. There are different types of lipids: triacylglycerols, wax esters, phosphoglycerides, sphingolipids, and sterols.

According to their structure:

  • Simple lipids ⇒ Composed of an alcohol molecule and fatty acids.
  • Complex lipids ⇒ They are composed of alcohol, fatty acids, and different non-lipidic components, such as<em> phosphates, amino acids, glucyds, amines</em>, etcetera.  These are the amphipathic molecules.

Membrane lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. In membranes, they are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.

Describe all the ways that a single tree might be involved in the carbon cycle.
avanturin [10]
<span>A single tree absorbs tons of carbon dioxide in its 30-year life cycle and it releases a ton of oxygen. The free nitrogen from the atmosphere is captured by the nitrogen-fixing bacteria and it converts nitrogen into nitrates and nitrites which is then absorbed by the plants. Trees, like all organisms, grow by adding mass (biomass). Carbon is the central ingredient in making that new biomass. Tree biomass is comprised of all parts of the tree; leaves, stems, branches, roots, tree trunks. The biomass of the woody tissue in the tree pictured on the right is made mostly of cellulose, a carbon compound. In a process called carbon fixation, plants transform CO2, an inorganic carbon compound into organic carbon compounds.</span>
