Notes

steroids(fat):
16,17,18

proteins:
Enzymes acts as a catalyst and is a type of protein that speed up chemical reactions
to make proteins, u need a chain of amino acids

Amino acid-
The monomers that make up proteins
there is amino group (left) and a carbonyl group
u move the amino acids and that's the function
peptide bonds: that's what amino acid are linked by
A functional peptide protein consist of one or more polypeptide twisted (coiled into a 3D shape)

The primary structure:
Like DNA letters (ABCs)
the sequence of Amino acids in a protein

secondary structure:
there's hydrogen bonding between the O
typical coil is with beta pleated sheet and alpha helix

tertiary structure:
include the bonds and van der waals interactions, and hydrophobic interactions
and disulfide bonds

Quaternary structure: results when two or more polypeptide chains form one macromolecule


sickle cell disease- an inherited blood disorder

if you change the pH, u can change the structure

protein when it lost its native structure, its called denaturation
chaperonins: specific type of protein "changeroom" proteins that helps other proteins fold (helps fold out into the tight shape)
