Biochemistry
Fatty Acids Fatty acids have a long hydrocarbon chain with a carboxyl (acid) group Typical for of fatty acids : CH 3 –(CH 2 ) n –COOH 12
Carboxylic Acids Bettelheim, Brown Campbell and Farrell Chapter 18.
What is the function of DNA?. Making proteins When genes are expressed, proteins are synthesized It involves two stages – transcription and translation.
Fats and Lipids. Lipids Lipids are varied in structure. –Many are insoluble in water because they lack polar groups. Types of Lipids and their Functions.
The BIG FOUR! ….well really the BIG 2 with a Little 2.
Chemistry of Water First cells evolved in water. –All living things are 70-90% water –water is polar, so hydrogen bond to each other. –Water is liquid.
Fatty Acids
PH Primer pH is a measure of H + concentration in a solution Note that even “pure” H 2 O has some H + due to dissociation (breaking apart) : H 2 O H +
