Lipids are different from other macromolecules because they are hydrophobic and don't dissolve in water.
They are hydrophobic and don't absorb water.
Are not truly polymers
Insolubility in water is the most
CARBOHYDRATES, NUCLEIC ACID,LIPIDS, AND PROTEIN
Most Biological molecules are put together or held together by covalent bonds. Covalent bonds form between two nonmetal elements.
1. nucleic acids: Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These molecules carry genetic information or form structures within the cells. 2. Proteins: alcohol dehydrogenase (an enzyme), and actin & myosin (structural proteins). Enzymes catalyze biochemical reactions in the body, while some proteins have structural or mechanical functions, such as actin and myosin in muscles. 3. carbohydrates: glycogen (storage of energy) and cartilidge in animals (structural components). 4. lipids: structural components of cell membranes, energy storage sources and intermediates in signaling pathways. Cholesterol, Vitamins A, D, E and K. BKM :)
Macromolecules are large molecules. Macromolecules are found in the proteins, carbohydrates, nucleic acid, and lipids in the body. Macromolecules are essential to the structure and function of a cell.
The difference between Carbohydrates (sugars) and Lipids: 1) sugars disolve in water lipids don't 2) sugars are made-up of subunits that form large polymers and lipids are not and don't form polymers. 3)Lipids store more energy than sugars. 4) sugars form stuctural components (cellulose in plants) and lipids form bountaries like the cell membrane due to hydrophobic hydrocarbons.
Lipids are fats, or to be technical, they are non-polar organic molecules. They do form large molecules but they do not polymerize.
A lipid is a large non polar biological molecule which is not a polymer. Insoluble in water and store energy and make up the cell membranes. So yes you are correct.
Covalent Bonds form large biological molecules
The large diversity of shapes of biological molecules is possible because of carbon.
Lipids are are large group of chemicals. There are many symbols for the the various molecules. I can't recall a symbol for the lipids as a group.
lipids
No, polypeptides are not lipids. Polypeptides are large molecules also called proteins; lipids tend to be relatively small molecules with an "ionic" end and a "greasy" end.
Bio-organics
Macromolucules means large molecules (macro-large) consists of :Carbohydrates(suger),lipids(fat),proteins
CARBOHYDRATES, NUCLEIC ACID,LIPIDS, AND PROTEIN
chemical digestion
Lipids The cell membrane itself moves things in and out of the cell
