You might now recall the pain of having to memorize the entire cellular respiration pathway and the structures of all the amino acids for your biochemistry class. It\u2019s true these concepts will be tested on the MCAT but not to as much depth. In this post, we will talk about MCAT amino acids and what you need to know about them for the exam.<\/p>\n<h2>What You Need to Know for the MCAT<\/h2>\n<p>If you talk to any student that has taken the MCAT, they will tell you that amino acids are a big deal. You need to have all twenty amino acids memorized. This includes the structure of the side chains, the p<em>K<\/em><sub>a<\/sub> of the side chain (if applicable), the one-letter code, and the three-letter code for each amino acid. In addition, you will need to be able to classify each as hydrophobic, hydrophilic, acidic, or basic. Below, we have an example of what you need to know for the acidic amino acid, glutamic acid:<\/p>\n<p><a href=\"https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh.png\" rel=\"attachment wp-att-293\"><img decoding=\"async\" class=\"alignnone wp-image-293 size-medium\" src=\"https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh-300x213.png\" alt=\"MCAT Amino Acids\" width=\"300\" height=\"213\" srcset=\"https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh-300x213.png 300w, https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh-768x545.png 768w, https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh-30x21.png 30w, https:\/\/magoosh.com\/mcat\/files\/2016\/05\/MCAT-Amino-Acids-Magoosh.png 959w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>This is a lot to memorize but, unfortunately, there is more.

MCAT amino acids are important. There are numerous ways that the exam can test these special organic compounds.<\/p>\n<h2>MCAT Amino Acids Practice Questions<\/h2>\n<p>To give you an idea of how the MCAT tests amino acids, we have a couple practice questions for you to try. If you think you know the answers, go ahead and let us know by commenting below!<\/p>\n<p>1. What is the net charge of the oligopeptide DVLNQEK at pH 7?<\/p>\n<p>A. +1<\/p>\n<p>B. 0<\/p>\n<p>C. -1<\/p>\n<p>D. -2<\/p>\n<p>2.
