The document discusses cost management using the example of a company. It examines how managers can analyze costs to make better business decisions. Managers should carefully consider all expenses, understand where money is being spent, and look for ways to reduce unnecessary costs. Proper cost management can help improve a company's overall financial performance and profitability.
This document describes several websites that provide free seminar papers, diploma papers, and matriculation papers to help students with their schoolwork. It lists the URLs of the websites and notes that they contain works from all subject areas as well as PowerPoint presentations and other educational materials. It highlights that the websites allow users to view the content and first few pages of each work so they can precisely select what best suits their needs, and also offers custom writing services for works not found on the sites.
1. Managers consider costs in three key areas: fixed costs which do not change with production levels, variable costs which increase or decrease depending on production levels, and semi-variable costs which have both fixed and variable components.
2. Cost-volume-profit analysis helps managers understand the relationship between costs, production volumes, and profits by examining total costs, fixed costs, variable costs, sales revenue and profits at different production volumes.
3. Break-even analysis identifies the production level at which total revenue equals total costs, meaning there is no profit or loss. It helps managers determine if proposed production levels will be profitable.
This document discusses several websites that provide free student papers, seminar works, graduate theses, and materials to help with school assignments. It notes that the sites contain works from all subject areas as well as PowerPoint presentations and other educational materials. Visitors can find seminar papers, graduate theses, and materials to help write unique student works. If a specific needed work is not available, custom papers and reference materials can be ordered.

LIPIDI predstavljaju grupu biomolekula različitog hemijskog sastava, vrlo
rasprostranjnih u svetu.
Zajednička karakteristika ovih jedinjenja je da su nerastvorljiva u vodi i polarnim
organskim rastvaračima a da su rastvorna u rastvaračima za masti odnosno nepolarnim
organskim rastvaračima kao što su etar, benzen, hloroform, petroletar i dr. Međutim
dolazi i do odstupanja od ove definicije npr: neki fosfolipidi su rastvorljivi u vodi a
nerastvorljivi u acetonima dok su sfingolipidi slabo rastvorljivi u etru. Iako su različite
hemijske strukture za sve lipide zajedničko njihovo biogenetsko poreklo odnosno ova
jedinjenja nastaju biosintezom iz istog prekursora aktivnog acetata ili tačnije acetil
koenzima A. Lipidi imaju višestruku ulogu u ‘ivom organizmu: učestvuju u izgradnji
ćelijskih membrane, predstavljaju rezervne oblike energije a neki od njih imaju zaštitnu
ulogu ili ispoljavaju hormonsko ili vitaminsko delovanje.
Hemijska klasifikacija lipida se vrši na osnovu hemijske strukture ili ponašanja pri
saponifikaciji. Na osnovu hemijskog sastava mogu se podeliti na:
-Jednostavne
-Složene.
Jednostavni lipidi prema analogiji se označavaju kao neosapunjivi lipidi i u njih
spadaju:
-Prostaglandini
-Terpeni
-Steroidi.
Složeni lipidi u molekulu sadrže ostatak barem jedne masne kiseline koja se pri
alkalnoj hidrolizi ovih lipida oslobađa u vidu alkalnih soli odnosno sapuna. Zbog
navedenog ovi lipidi se nazivaju osapunjivi lipidi. Osapunjivi lipidi se dele na:
-Neutralne masti
-Fosfogliceride
-Sfingolipide
-Voskove.
Zajednčki strukturni element svih osapunjivih lipida su masne kiseline.
Imenom masne kiseline nazivaju se monokarbonske kiseline obično parnog broja
ugljenikovog atoma pravog niza koji može biti zasićen sa 4 do 30 C atoma ili pak

nezasićen sa istim brojem C atoma. Mogu sadržati jednu ili dve dvostruke veze dok neke
retke poseduju i trostruke veze. Masne kiseline se u živom organizmu nalaze slobodne ili
u obliku etra, što znači da mogu biti biljnog ili životinjskog porekla. Masne kiseline
životinjskog (animalnog) porekla su najprostije strukture dok su masne kiseline biljnog
porekla najrazličitije po strukturi. Među zasićenim masnim kiselinama najčešće se sreću:
-Palmitinska CH3(CH2)14COOH
-Stearinska CH3(CH2)10COOH.
Nezasićene masne kiseline dominiraju nad zasićenim masnim kiselinama u prirodi.
Njihova zajednička karakteristika je dvostruka veza na cis-konformaciji i prve dve se po
pravilu javljaju između C-9 i C-10 atoma. Najpoznatije nezasićene masne kiseline
su:
-Oleinska (sadrži jednu dvostruku vezu),
-Linolna (sadrži dve dvostruke veze),
-Linoleinska (sadrži tri dvostruke veze).
