Proteins Flashcards
How are amino acids connected
By peptide bonds through dehydration reactions
Made of
C h o n and sometimes phosphorus and sulfur
Another term for a protein is
A polypeptide
Primary
Sequence of amino acids
Secondary
When the protein can coil to form aha helixes or beta pleated sheets
Simple proteins
Made entirely of amino acids
Albumins and globulins
Globular in nature
-functional proteins that act as carriers or enzymes
And usually found in serum
Scleroproteins
Collagen is an ex
Conjugated proteins
-contain a simple protein portion plus atleast one nonprotein fraction
Lipoproteins
Protein bound to a lipid
Mucoproteins
Protein bound to a carbohydrate
Chromoproteins
Protein bound to pigmented molecules
Metallroteind
Protein complexed around a metal ion
Nucleoproteins
Protein bound to nucleic acid either dna or rna
Hormone function
Act as chemical messengers secreted into circulation
Enzyme functions
They are catalysts that increase the rate of a chem rxn
Structural proteins function
Contribute to the physical support of a cell or tissue
-may be extracellular
Ike collagen in csrtilage bone or tendons
-or intracellular like proteins in membranes
Transport proteins
Carriers of important materials
-ex is hemoglobin
Antibodies function
bind to foreign particles and start the chain of events to protect against them
