Chap 3 Proteins, Carbs, And Lipids Flashcards
Mono macromolecules
Amino acid
Monosaccharide
Nucleic tide
Polymer macromolecule
Protein
Carbs
Nucleic acid
What characteristics of carbon ?
Four valence electrons
bond with a wide variety of other elements and function groups
Bonds are strong and stable
Carbon skeleton
Carbon chain it’s the backbone,
basic shape ,
framework
Functional group definition
Specific combinations of bonded atoms,
Functional group personality l
A molecule that shows characteristics set of physical and chemical properties regardless of the molecule of which is a part
- the components of organic macromolecules that are most commonly involved in chemical reactions, they are the part of the molecule ( determine how reactive and where reactions occur)
The importance of functional groups
Each function group gives different and specific chemical properties to local site
( localized area will have their own personality)
Importance of functional group pt 2
Determine physical shapes
Type and strength of interaction
Determine nomenclature
Condensation
Produces water and consume energy
Hydrolysis
Hydrolysis takes water to break things down and energy is released
Protein and their functions
Enzymes = speeds up chemical reactions
Structural proteins= provides physical stability and movement
Signaling proteins= control physiological process
Proteins
Proteins are made from 20 amino acids
Amino acid
Amino acid bonds Together covalently in a condescending reaction by peptide linkages
Bond linkage
Bonds linkages either will be bond or linkage
Primary structure
Primary structure of a protein is a sequence of amino acids. This sequence determines the proteins final shape
Primary structure
Forms a a variety of loops, coils, and folded sheets
1st structure of peptides
First structure of protein is held together by covalent bond
Protein altered
Proteins can be altered by the ph,
High temp
High condensation
Non polar substance
( when bond is broken protein form is altered
Protein bind
The biding depends on two general protein properties
Shape
Chemistry of exposed surface
Protein shape
Protein shape can be altered as results of interaction with other molecules
And covalently modification
Protein bind
Protein can bind to the wrong molecule
Carbs
Formula c 1h2o1)n
Four major biochemical roles
Sources of stored energy
Used to transport stored energy
Serves as carbon skeletons to be arranged to form new molecules
Structure support
Carbs sugar names
Monosaccharides = one simple sugar
Disaccharides = two simple sugar
Polysaccharide = up to thousands of monosaccharides
(Most names for sugars end I ose
