How well do you know your proteins? -Proteins are the building blocks for living cells. - Proteins account for more that half of dry mass of most cells. -They are instrumental in almost everything organisms do. -They speed up chemical reactions. -Thet provide structural support and aid with defense against foreign substances.
MACRO MOLECULES
CARBOHYDRATES Provide energy to living cells Include sugars and polymers of sugar. Enter the blood faster than all other macromolecules. Components of cell structure Food storage
REMEMBER FOR TEST!!!!!!!!!!!!!!!! A Nucleic Acid is a macromolecule composed of chains of nucleotides; polymers that carry and transmit genes. Examples: DNA is inherited from one generation to the next & reproduced in each cell; provides direction for its own replication& directs RNA synthesis. RNA is known as the 'messenger' and it directs protein synthesis.
4 Things I KNOW about Lipids: 1. It is an oily compound insoluble in water but soluble in organic solvents.; have little or no affinity for water. 2. They are the only class of large biological molecules that don't have polymers. 3. They have a hydrophobic behavior based on their molecular stucture. 4. Major types are fats, phospholipids, and steriods
