amino acids

Fitness tip #2

To build your muscles, fuel your body before and after a workout!

Make sure you’re getting a good balance of carbs, proteins, fats, amino acids, and calories!

I like to have a meal or snack and protein bar an hour or so before your workout and a protein shake and meal after! Everybody’s body is different and has different needs so listen to your body, If you are feeling tired and sluggish after or during a workout you probably need to eat more.

Also try to keep your calorie and protein intake up even on days you are not working out!


Knowing the 20 Amino Acids is definitely a MUST for the 2015 MCAT 

Amino acids that are usually negative (i.e. de-protonated) at physiological pH:

- Glutamate (E) Glu, and Aspartate (D) Asp

Amino acids that are usually positive (i.e. protonated) at physiological pH:

- Lysine (K) Lye, Arginine ® Arg 

Histidine is sometimes charged at physiological pH. 

physiological pH = 7, Neutral 


28 July 2016, 13:00 || it’s just me, myself, and i, solo ride until i die || did lots of bio today! finished the entire unit of biochem, but i’m still in the process of rewriting my protein notes. these amino acids are going to be impossible to memorize :(

Person whose parent studied nutrition said that it's "very hard" for vegetarians to get the "correct proteins and vitamins". Is there an "incorrect" protein? And how true do you think it is that it's "very hard"? Because maybe I'm doing it wrong, but it hasn't been that hard for me to get what I thought I needed.

It makes sense they would think that. It was believed from 1970-1990 that it was really difficult for vegans and vegetarians to get the “right” kind of proteins because of the book Diet for a Small Planet. (x) The author made it seem as if obtaining plant proteins were very complicated because you had to combine different amino acids in a single meal. We know better now; our livers can store various amino acids and this careful combination of different amino acids every meal isn’t necessary. (x)

Lysine is the most important amino acid to watch out for, and if you’re meeting your recommended daily allowance of Lysine, then more than likely you’re getting enough protein. (x)

It sounds very technical and complicated, but it’s basically saying eat high-quality protein every day.

Per serving, legumes and seitan are the foods highest in the amino acid lysine. Tofu, tempeh, soy meats, lentils, and seitan are the highest, followed by other legume foods. Quinoa, amaranth, pistachios, and pumpkin seeds are also decent sources of lysine.

So there you go. Eat some beans, tofu, or plant-based meats every day and you probably don’t have to even think about it (though having regular checkups and blood draws to make sure everything is going well is a good idea in general, as vitamin D deficiency is a pretty common occurrence in the general population).

You can even buy protein powder and make a snack of it with a shake if you’re really concerned. Protein deficiency is almost unheard of in the US if you’re getting enough calories (because even vegetables contain an assortment of amino acids), with the exception of people with health problems or tendencies toward deficiencies. I know of at least one vegan who has problems absorbing protein, so she has to consume a bit more. And she’s been vegan for decades, and is an older woman in good health, so she’s obviously doing something right.

Quick fact. Ready?
Valine, Leucine, and Isoleucine are some of the three most important Amino Acids for muscle synthesis. These three in particular can contribute up to 10% of energy during a moderate to high intensity workout. That’s why they’re heavily including in BCAA mixtures.

Not cool, Tumblr, to eat my posts.

My original post, in summary: I wanted some Cocoa Krispies in my oatmeal this morning, don’t judge me. It wasn’t as good as I had hoped. Added some PB for a total of 425 calories. Kind of high but, eh, all in the name of trial and error.

Kickboxing was great again last night - maybe tomorrow I’ll remember a post-class selfie? I’m trying out some new Amino Acid pre and post workout aids. Vital, from Target. The pre workout was great - a nice, steady energy boost and no jitters. The post workout recovery I *think* helped but time will tell. I slept like a dream last night. 🤓


Genetic Code:
The instructions in a gene that tell the cell how to make a specific protein. A, C, G, and T are the “letters” of the DNA code; they stand for the chemicals adenine (A), cytosine ©, guanine (G), and thymine (T), respectively, that make up the nucleotide bases of DNA. Each gene’s code combines the four chemicals in various ways to spell out three-letter “words” that specify which amino acid is needed at every step in making a protein.

Chickens on an unsupplemented vegetarian diet typically fall short of an essential protein-based amino acid known as methionine, and without it, they fall ill. Worse, the birds will also turn on each other, pecking at each other in search of nutrients, and these incidents can escalate into a henhouse bloodbath, farmers say.
Mini fact #4

Glycine is the only amino acid without any stereochemistry.
All the others have S stereochemistry except Cystine, which has R. (Assigned using CIP rules)
Biochemists bypass this and just say that all natural amino acids are left handed.
