Bio Chem- Proteins Flashcards
To understand what proteins are and how they function
What are proteins
Proteins are everywhere.
EX: hair, skin, nails, enzymes, spider webs
What do proteins contain
contain C, H, O, N
What is proteins structure
Amino Acids - Polypeptides - Protein (itself)
Amino Acids (a.a )
they are proteins monomer
20 different kinds of a.a
Polypeptides
proteins polymer
- it is a single strand of a.a together OR many a.a together that are a strand
Protein (itself )
many polypeptides bonded together
Think about this
N-C-C
The N must be on the end
And a C in the middle
What is an amino group
H
|
H–N
What is a carboxyl group
O
||
C–OH
What is an R group
variable or R group
there are 20 different types
each R group represents a diff a. a
What changes in proteins
only the R groups, the carboxyl, and amino groups stay the same
What is a peptide bond
amino acid+ amino acid
When 2 amino acids are added together they dehydrate or condensate and the bond that connects the carbon and nitrogen is a peptide bond
What are the lines that connect 3 different groups are
peptide bonds
What does DNA do
it carries the code; says what it will look like
