Flashcards in Proteins, Amino Acids, and Enzymes Deck (10):
1

proteins

subunits: amino acids
importance: hormones, enzymes, transport
polymerized -> chains (polypeptides/proteins)

2

r groups

gives unique properties and determines the chemical properties
eg: hydrophobic, polar, (-)(+)

3

amino acids

eg glycine, proline

protein monomers, connected by peptide bonds thru dehydration synthesis

4

4 levels of protein organization

primary: linear
secondary: pleated sheets, helices
tertiary: 3D shape of entire protein
quaternary: combo of 1(+) proteins

5

nucleic acids

eg RNA and DNA
subunits: nucleotides

6

components of nucleotides

phosphate, pentose sugar, bases

7

5 bases

Adenine, Guanine, Cytosine, Thymine, Uracil

8

RNA vs DNA

D: double helix, deoxyribose sugar, A-T/G-C
R: single stranded, ribose, A - U/G - C

9

enzymes

almost always proteins
speeds up chemical reactions w/o being consumed
very specific (unique shape of active sites)

10

enzyme-substrate complex

substrates + active sites -> substrates become products that are released
